摘　　要：从理论上分析负载敏感泵控制原理,建立了负载敏感泵数学模型;搭建负载敏感泵响应特性仿真模型,利用AMESim批处理功能探讨了主要参数对响应速度的影响规律;结合理论及仿真分析,提出一种结构优化方案。仿真结果表明:优化后变量泵响应速度提高33.2%。以某28型旋挖钻机进行试验研究表明:优化后变量泵响应速度提高32.8%。与仿真结果具有较好的一致性。This paper explains a load sensitive pump response performance theoretically and builds its mathematical and simulation model. Then,AMESim batch function is used to explore the response speed of the main parameters.After theoretical and simulation analysis,the structural optimization of the load sensitive pump is carried out. The simulation results show that: the response speed of the optimized load sensitive pump increases by 33. 2%. Finally,28-type rotary drilling rig is used for test research. The test results also show that the response speed of the optimized load sensitive pump increases by 33. 2%. The simulation results agree well with the test results.
