摘要
针对排管机液压执行机构与液压泵源之间需要长管道远距离布置的特点,对此类型排管机负载敏感液压系统的数学模型和试验进行分析,确定管道效应对系统稳定性和响应快速性等动态特性的影响及影响因素,并结合深部探测实际工况对排管机液压系统的具体要求,运用AMESim软件模拟管道效应对负载敏感液压系统的影响。仿真结果揭示管道长度与管道内径对负载敏感液压系统动态特性的影响规律。运用上述规律,合理地选择和布置排管机液压系统的管路,可在一定程度上规避管道效应带来的不利影响。
How to analyze tube effect on load sensitive hydraulic system in the tube drawbench.In view of a feature that there is a long distance to lay tubes between the bench's hydraulic actuator and hydraulic pumping source we analyze similar mathematic models and tests with analyses thereof before determining tube effects on the system's stability and rapid responding,etc in terms of dynamic features and their effective factors,which was considered with actual conditions so detected and their requirements for the hydraulic system before using AMESim software to simulate tube effects on the load sensitive hydraulic system.By using the laws above we logically selected and arrayed pipelines for the hydraulic system that can to same degree avoid bad inferences from the pipe effects.
