Stress and strain are commonly used mechanical parameters in engineering. By measuring the strain and stress of mechanical parts and structures, it is possible to analyze the stress and working conditions, verify design calculations, and determine the working process and the mechanism of certain physical phenomena.
The phenomena of noise and vibration in the car interior are the superimposed sum of various excitations after reaching the target position through different paths. Nowadays, the NVH performance has become the main indicator for market competition in the vehicle industry. In order to further improve
Strength is the residual deformation capacity for the car parts to resist to prevent fracture or to exceed an allowable limit once loads are applied to them. Therefore, strength is an important indicator to measure the bearing capacity of the car parts.
