【摘要】 为了在新型地铁整平装置的设计研发基础上,进一步优化精密整平作业车液压系统的设计及其关键参数设定,绘制了精密整平作业车的液压系统原理图,利用AMESim软件分别对振捣系统、螺旋布料系统和调平系统进行了建模与仿真分析。仿真分析结果表明,随着振捣频率的增加,振捣马达流量波动越来越大,为保证振捣系统性能,振捣频率设计为30Hz;系统中加装蓄能器能够提升系统的稳定性和可靠性,降低液压冲击,延长液压元件使用寿命;阻尼孔直径影响调平油缸升降速度,阻尼孔直径增大,油缸升降速度也随之增大。为了保证整平工作质量,使升降速度处于标准范围内,最终确定阻尼孔A1的直径为0.9mm。更多还原

【Abstract】 In order to further optimize the design and key parameter setting of the hydraulic system of the precision leveling vehicle on the basis of the design and development of a newsystem,the hydraulic system schematic diagram of precision leveling vehicle is drawn,and the vibrating system,screw fabric system and leveling system are respectively modeled and simulated by AMESim software.The simulation results show that the vibration frequency is set as 30 Hz to ensure the performance of the system.Adding accumulator in the system can improve the stability and reliability of the system,reduce hydraulic impact,and extend the service life of hydraulic components.The diameter of damping hole affects the lifting speed of oil cylinder in leveling:as the diameter of damping hole increases,the lifting speed of oil cylinder also increases.In order to ensure the working quality of leveling,the lifting speed is within the standard range,and the damping hole A1 diameter is finally determined to be 0.9 mm.更多还原
