摘　　要：液力机械自动变速器是矿用车辆传动系统中的重要部件。为反映变速器真实的运动状态,可应用Maplesim软件建立仿真模型。根据变速器各组成部分的功能,将其分为液力变矩器、行星轮系和电子换挡控制单元,并分别运用现有的数学模型建立仿真模型,保证了模型的准确性和真实性。建立出典型的液力机械自动变速器仿真模型,能够模拟车辆从静止升至最高档位的运动状态。对动态模型的仿真结果进行分析,车辆运动状态符合车辆升档的真实情况,换挡过程加速度的波动范围在（0.4~1.5）m/s2。较其它仿真方法简化了行星轮系的分析过程,在研究行星轮系各组成部分运动状态上具有很大优势。Automatic transmission is an important infrastructure for mining trucks.It describes a simulation model in Maplesim to simulate the transmission real motions.Based on the different functions of transmission components,it can be divided into torque converter,planetary sets and electronic control unit.In addition,it is implemented by using the present mathematic method to build simulation model for ensuring the accuracy and facticity.Operating the model from statistic state to the highest gear gradually,the dynamic simulation model had been analyzed.The simulation results represent the model motion states accord with the real vehicle shifting condition,and the acceleration variation ranges from 0.4m/s2 to 1.5m/s2.Meantime,this approach simplified the analyzing method for planetary sets to some extent and it has big advantages in researching the motions for all elements of planetary set.
