Optimization and simulation verification ideas for air spring structure
In the process of structural design for air spring,there are always irrational processes.In order to avoid waste in sample production,and reduce the design and manufacturing costs,FEA method was used to simulate and optimize air spring structural parts(as pistons,rings)and elastic parts(as bellow)to meet the input parameter requirements.Based on the simulation of load transmission capacity,vibration absorption capacity,fatigue life,and high-temperature resistance,optimization of performance parameters and structure was achieved to form a simulation idea and method for air springs,so as to achieve the design goals of air springs.By establishing a vehicle model to simulate the driving conditions of vehicles under different road conditions,loading experiments were conducted on the model to simulate the force and displacement changes during vehicle acceleration and braking.Combined with the principles of vehicle dynamics,the driving stability and riding comfort of air springs were analyzed,and the vehicle simulation ideas were derived.Through the above complete simulation ideas,it was expected to shorten the research and development cycle,reduce trial production and testing costs,and improve research and development efficiency.
