1、上海交通大学硕士学位论文静压传动装载机驱动桥离合器动态过程仿真与实验姓名：阮观强申请学位级别：硕士专业：车辆工程指导教师：陈俐;朱为20081201上海交通大学工程硕士学位论文摘要中的SIMULINK模型。提供了充气压强、角速度、角加速度、滑摩功、冲击度的仿真结果，并考虑了输入进气孔面积和转动惯量对结合品质的影响。根据仿真结果，通过比较得出驱动桥离合器在结合过程的理想气压输入值。本文对静压传动装载机驱动桥离合器的进行了实验研究，通过用底盘测功机加载负荷进行台架实验，对驱动桥离合器结合时的控制气压值和气缸活塞和太阳轮盘的转动角
2、速度进行了实验研究，仿真结果通过实验验证。本文的研究对实车控制具有指导意义，并对新型的驱动桥离合器的开发工作具有工程实际价值。关键词：装载机，驱动桥，离合器，系统仿真，实验II上海交通大学工程硕士学位论文摘要HYDROSTATICTRANSMISSIONWHEELLOADERDRIVINGAXLECLUTCHDYNAMICPROCESSIMULATIONANDEXPERIMENTABSTRACTCurrently,astorqueconverterisadoptedinthedrivetransmissionpartindo
