摘要
为研究间隙误差对液压约束活塞发动机流量脉动的影响,在ADAMS中建立其含有间隙误差的主运动系统动力学模型,将ADAMS中得到的模型数据导入AMESim中,建立液压系统模型。通过对比不同间隙误差模型的参数输出,分析间隙误差对系统流量脉动的影响。研究结果表明,在一定范围内,间隙误差对流量脉动有明显的影响,并随着间隙误差的增大而增加;而且,连杆大头和曲轴曲柄之间转动副径向间隙误差对系统流量脉动的影响最大。
To study the influence of clearance error on the flow pulsation of hydraulic confined piston engine,the dynamical model of the main motion system of HCPE with clearance error is established in ADAMS.Then,the model data from ADAMS is imported into AMESim,the hydraulic system model is established and by comparing the output of parameters between models with different clearance error,the influence of clearance error on the flow pulsation of the system is analyzed.The results show that the clearance error has obvious effect on the flow pulsation of the system,and it increases with the increase of the clearance error.The radial clearance error of the revolute joint between the connecting rod and crankshaft crank has the greatest impact on the flow pulsation of the system too.
