Lightweight design and optimization of lock bracket for commercial vehicle
The lightweight design of automotive parts is one of the main ways of automobile lightweight,and the lightweight design including materials and structures has been carried out for the lock body bracket parts of commercial vehicles.319S aluminum alloy was selected as the lock body bracket mate-rial,and through the establishment of a three-dimensional model and topology optimization of the origi-nal lock body bracket for commercial vehicles,the topology optimized bracket structure was further im-proved under the condition of ensuring the performance of the lock body bracket,and the finite element analysis of the improved lock body bracket was carried out.The results show that the maximum stress of the optimized lock body bracket is much less than the allowable strength of 319S aluminum alloy,and the lightweight effect reaches 83.97％.
