In order to accelerate the vibration attenuation of the frame and body and improve the ride comfort of the vehicle, vibration absorbers are installed in the suspension system of most automobiles. Both the shock absorber and the elastic element are installed in parallel.

Hydraulic shock absorbers are widely used in vehicle suspension systems. The principle of the hydraulic shock absorber is that the oil in the shock absorber shell flows repeatedly from one cavity to another through some narrow cavities when the piston moves in the cylinder cylinder when the driver and the bridge move reciprocating relative to each other. At this time, the friction between the hole wall and the oil and the internal friction of the liquid molecule form a damping force to the vibration, so that the vibration energy of the body and the frame is converted into heat energy, which is absorbed by the oil and shock absorber shell, and then emitted into the air. The damping force of the shock absorber increases or decreases with the relative velocity of the frame and the axle, and is related to the viscosity of the oil. Therefore, it is required that the viscosity of the oil used in the shock absorber should be as little as possible affected by the temperature change, and has the properties of anti-vaporization, anti-oxidation and non-corrosion to various metal and non-metal parts.

      Winter is quickly approaching and that means fewer hours of daylight. To be sure you can be seen by others and your visibility is not compromised, check your vehicle’s lights and wipers, says the non-profit Car Care Council.
      “The days are getting shorter, so it is a good time to check that your vehicle’s wipers and lighting are working properly because the chance of an accident increases if you can’t see or be seen,” said Nathan Perrine, executive director, Car Care Council. “From the driver’s seat you may not notice a light that isn’t working, so check all of your car’s lights and replace those that are out. Also, be sure to inspect and replace wiper blades so you can see clearly when wet weather hits.”
      The wiper system keeps excessive water, snow and dirt from building up on the windshield, maintaining clear visibility. Many factors can accelerate the replacement interval of wipers, including operating conditions (winter conditions are tough on wiper blades), frequency of use, material and type of wipers and sunny weather. In fact, wiper blades can deteriorate faster and need more frequent replacement in desert states.
      Lights are normal wear items that require periodic inspection and replacement. The lighting system provides nighttime visibility; signals and alerts other drivers; and supplies light for viewing instruments and the vehicle’s interior. In addition to replacing dimming, rapidly blinking and non-functioning lights, the following tips can help keep you safe: 
      If there is any doubt on whether or not your headlights should be on, turn them on. Lights not only help you see better in early twilight, they also make it easier for other drivers to see you. Keep headlights, tail lights and signal lights clean. External dirt and debris can dim operational lights from being seen by others. Make sure that your headlights are properly aimed. Misaimed headlights blind other drivers and reduce your ability to see the road. Don’t overdrive your headlights; you should be able to stop inside the illuminated area, otherwise you are creating a blind crash area in front of your vehicle.

      link hidden, please login to viewKeeping your vehicle clean inside and out can pay big dividends when it comes to maintaining its long-term value. The non-profit Car Care Council suggests some simple steps to keep your vehicle clean and protect it from the elements so it retains its resale and trade-in value. Declutter – Start the cleaning process by removing excess clutter from inside the car as it can be distracting and hazardous, especially when debris finds its way near the gas and brake pedals. Don’t forget to clear out items that have accumulated in the trunk as they can add extra weight and reduce fuel efficiency.
      Clean the Interior – The next step is to thoroughly clean the interior, wash the windows, and clean and install floor mats. Be sure to vacuum on a regular basis. A clean and orderly interior allows you to spot issues in the cabin so you can get them repaired before they get worse.
      Wash the Exterior – Give the car a good wash from top to bottom using products specifically made for automobiles (not dish detergent). Always clean the tires and wheels before washing the body, and don’t use the same washing mitt or cloth for both.
      Wax Twice a Year – Waxing not only protects a vehicle’s finish, but it also makes subsequent washing easier. Before proceeding, make sure there are no foreign particles on the paint. It is important to note that waxing should be done in the shade, not direct sunlight.
      Fix Chips – If there is minor paint damage, cover the paint chips as quickly as possible to prevent further damage. For a quick fix until you can get paint touchup supplies, dab a little clear nail polish on the scratch.
      “A clean car is money in the bank,” said Rich White, executive director, Car Care Council. “Since many vehicles are sitting idle for long periods these days, it is important to remove the grime and sediment that can build up on the outside of the car to help prevent rust. It’s also a good idea to wipe the dashboard, steering wheel, cup holders, door handles, vents and console with a quality, all-purpose automotive cleaner to disinfect the interior areas of the vehicle.”

    • OEM vs. Aftermarket Parts for Your Car: How to Choose
      When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.

      Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.

      You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.

      Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.

      Hydraulic shock absorbers are widely used in vehicle suspension systems.

At this time, the friction between the hole wall and the oil and the internal friction of the liquid molecule form a damping force to the vibration, so that the vibration energy of the body and the frame is converted into heat energy, which is absorbed by the oil and shock absorber shell, and then emitted into the air. The damping force of the shock absorber increases or decreases with the relative velocity of the frame and the axle, and is related to the viscosity of the oil. Therefore, it is required that the viscosity of the oil used in the shock absorber should be as little as possible affected by the temperature change, and has the properties of anti-vaporization, anti-oxidation and non-corrosion to various metal and non-metal parts.

      Basic knowledge of shock absorbing rubber products
      1. Static stiffness: refers to the ratio of the change of pressure (or tensile force) to the change of displacement in a given displacement range. The static stiffness must be measured within a certain displacement range. The static stiffness values measured in different displacement ranges are different, but some families require the change curve measured in the whole displacement range.
      2. Dynamic stiffness: It refers to the ratio of the change of pressure (or tensile force) to the change of displacement of damping rubber in a certain displacement range and a certain frequency.
      3. dynamic magnification: the ratio of the dynamic stiffness to the static stiffness measured by the damping rubber in a certain range of displacement.
      4. Loss coefficient: There is a phase difference between the deformation of rubber and the stress of rubber in the course of the force acting on damping rubber, and the stress of rubber is generally ahead of the phase angle of the deformation of rubber.
      5. Torsional stiffness: refers to the ratio of torsional moment to torsional angle of damping rubber within a certain range of torsional angle.
      6. Durability: It refers to the number of times of vibration when the rubber is in good condition after n times of reciprocating vibration under certain preloading load, amplitude and vibration frequency in a certain direction.Thanks for the help and support of Chongqing Feilong Jiangli Auto Parts technical department.

      The greater the damping force of the shock absorber, the faster the vibration is reduced, but the effect of the parallel elastic elements can not be fully exerted. At the same time, the excessive damping force may also lead to damage to the connecting parts and frame of the shock absorber. In order to solve this contradiction between elastic elements and shock absorbers, the following requirements are put forward for shock absorbers.
      (1) In the compression stroke of the suspension, the damping force of the shock absorber should be small so as to make full use of the elasticity of the elastic elements to mitigate the impact.
      (2) In the suspension stretching stroke (the distance between the bridge and the frame) the damping force of the shock absorber should be large in order to reduce the vibration rapidly.
      (3) When the relative speed between the axle (or wheel) and the frame is too high, the shock absorber should be able to automatically increase the area of the liquid flow passage, so that the damping force is always within a certain limit to avoid excessive impact load.
      Cylinder shock absorber is widely used in automobile suspension system, and it can reduce vibration in compression and stretching stroke. It is called bidirectional action shock absorber, and a new type of shock absorber is adopted, which includes air-filled shock absorber and resistance adjustable shock absorber.
