Factors related to cushioning effect of suspension rubber buffer front axle

- May 02, 2019-

The cushioning effect of the suspension rubber buffer front axle is affected by many factors, such as static stiffness, which is the ratio of the amount of pressure change to the amount of change in displacement. The static stiffness values measured by different displacement ranges are different; there is also the ratio of the amount of pressure change to the amount of displacement change at a certain frequency within a certain range of displacement.

 

The dynamic magnification and loss factor are also the influencing factors of the buffering effect of the suspension rubber front axle. The former is the ratio of dynamic stiffness to static stiffness; the latter is the tangent of the rubber phase and rubber deformation phase angle δ, ie the loss coefficient τ=tgδ In addition to this, there is also the durability and compressive modulus of the suspension rubber buffer front axle.

 

The durability of the suspension rubber buffer front axle refers to the number of vibrations when the rubber is reciprocally vibrated n times after the reciprocating vibration of the rubber in a certain direction at a certain preload, amplitude, and vibration frequency. Durability is an important indicator of the safety performance and overall performance of a rubber part.

 

The compressive elastic modulus of the suspension rubber buffer front axle is the ratio of the normal stress and the corresponding positive strain in the elastic deformation phase, that is, the force/deformation amount, and the elastic modulus of the rubber is 7.8 mpa. This means that there is more force per unit volume of rubber than metal buffering.
