Failure Cause Analysis of Plate Spring Support for Truck
Failure analysis is an important part of solving quality problems.According to the failure factors of ADI leaf spring support for heavy trucks,the failure causes were analyzed from the aspects of geometric shape design,body microstructure and mechanical properties,casting defects and strength simulation.The results show that ADI material can meet the performance requirements of automobile leaf spring support,and the main reason of fracture is that the stress is too concentrated due to the small R-angle of structural design.
