摘要
以车辆换挡缓冲阀为研究对象,建立了缓冲阀工作过程的数学模型。然后利用Matlab/simulink分析了其结构参数对缓冲压力特性的影响。结果表明,缓冲阀芯和节流孔直径对缓冲压力特性的影响较大,缓冲弹簧和回位弹簧的刚度对缓冲压力特性有一定的影响。最后通过试验验证了缓冲阀数学模型的准确性。
A vehicle shifting buffer valve is the research object in this paper,and a mathematical model of its work process is established.The influence of its structure parameters on the buffering pressure characteristics is analyzed by Matlab/simulink.Results show that the impact of the diameter of its buffer spool and throttling orifice on the buffering pressure characteristics is larger,and the stiffness of the buffer spring and the return spring have some influence on the buffering pressure characteristics.
