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.
Road Spectrum Acquisition, especially the load spectrum acquisition, is to provide reliable data support for the laboratory bench tests or multi-body dynamics simulation analysis, so that engineers can predict and judge accurate fatigue life of each automobile part.
With the continuous expansion of the urban construction scale, the composition of urban domestic waste has changed greatly. There are fewer sites available for landfills in the suburbs, and people have to consider establishing grave disposal sites in the outskirts.
