摘要
Abstract
In view of the hyperstatic problem of multi-axis suspension in virtual rail tram,a solution for interconnected balanced suspension is proposed.Based on the establishment of the thermodynamic model for the air spring and the thermodynamic model for the connecting pipeline,the effectiveness of this optimization scheme is verified through joint simulation with the dynamic model.The interconnected air suspension can optimize the ride comfort of the vehicle,and improve the dynamic axle load distribution.The influence of the interconnected pipe diameter on the kinetic performance is analyzed.The results show that by using this scheme,the ride comfort and load balance of the digital tram end car can be improved;when the connecting pipe diameter is 10～20 mm and the speed passes the speed belt,the interconnected air balance suspension increases by 2%～6%compared with the original structure,and the peak dynamic load of the first and second axes is reduced by 2%～16%compared with the original structure;with the increase of the diameter of the connecting pipeline,the ride comfort of the vehicle is improved,and the balance effect of the dynamic load is more obvious;the pipe diameter of 15 mm can better balance the dynamic performance of the speed belt and the slope point.关键词
