Optimal Design and Test Research of Rubber Auxiliary Spring for Medium-Sized Truck

摘要

With CAE analysis software, combined with the characteristic of rubber auxiliary spring force, based on the elastic curve of design requirements as optimized objective, the optimal design of structure parameters for rubber auxiliary spring is realized. The optimized prototype for trial production makes the weight of suspension system successfully reduced by up to 20 %. It realizes the lightweight of vehicle. Test project design and verification on the rubber auxiliary spring body and suspension system are conducted, and the results show that rubber auxiliary spring is feasible in medium-sized truck applications and is worth to be popularized.
