摘　　要：节油轻载内燃机配气机构中气门开启机构动态特性取决于液压缸动态响应过程,液压缸动态特性受多种因素影响,试验中液压缸活塞杆回退慢,行程10mm时,其动态响应时间达不到0.5s。为了优化液压缸动态特性,建立了工作机构液压系统的数学模型,分析其影响因素,采用AMESim对主要影响因素进行优化仿真,并对仿真结果进行了试验验证,得出了给定条件下液压缸动态特性的影响规律。Valve open institution dynamic characteristic depends on hydraulic cylinder＇ s dynamic response in the oil-saving light load institution of internal combustion engine.Hydraulic cylinder dynamic characteristic is affected by many factors.The hydraulic cylinder piston rod back slowly,when return 10 millimeter,the dynamic response of time is more than 0.5 seconds.In order to optimize hydraulic cylinder dynamic characteristic,it is necessary to upbuild the math model.Based on the model,analysis the affecting factors.Using AMESim to optimize the major influential factors.And the simulation result is verified by experiment.The hydraulic cylinder dynamic characteristic influence law is drew in the given condition.
