根据整车厂提供的30t某8×8特种车参数,结合某公司400 kW自动液力变速器的性能参数,应用MATLAB编程计算,分析了发动机与液力变矩器的动力匹配性能、整车动力性能以及液力缓速器的制动效果。结果显示:整车最高车速达102.96km/h;最大爬坡度>60%;整车起步加速至60km/h最小耗时20.96s;液力缓速器1挡制动效果不理想。
According to the 30t 8 × 8 special vehicle parameters provided by the OEMs and the performance parameters of a 400 kW automatic hydraulic transmission of a company, the dynamic matching performance between the engine and the torque converter is analyzed using MATLAB programming. Performance and braking effect of the retarder. The results show that the maximum speed of the vehicle reaches 102.96km / h, the maximum degree of climbing is more than 60%, the minimum speed of the vehicle accelerates to 60km / h, and the minimum time is 20.96s.
