Analysis of suspension element of car body on the example silentblock

The article presents a still important aspect of the construction and operation of the vehicle. The most loaded part of the suspension of a vehicle has been discussed, for example, rubber-metal bushing (silentblock). This component directly affects the safety and comfort of drive. It also presents the main varieties of construction and signs of usage of those elements. It has comprised of properties of the rubber and polyurethane bushings. Mechanical calculation of silentblock model has also been presented. 3D numerical analysis was carried out on the basis of the model by using two types of rubber bushings with different hardness. The results of simulations carried out in the system MSC.MARC has been shown. On these basis, there were selected and given numerous conclusions for utilitarian character.
