液压系统中液压阀的振动响应分析

摘要

This paper described the development of the hydraulic system and its vibration problems, and analyzed the steady-state response when the hydraulic valve in the hydraulic system bears irregular cycles force. Under the known law of the vibration displacement hydraulic valve, we also analyzed the way to solve the vibration response. Giving an example when the hydraulic valve was subjected to harmonic base excitation vibration, we obtained the formula and use matlab draw the vibration response curve.%本文简要介绍了液压系统的发展及其振动问题，在液压系统中把液压阀看成一个整体进行建模，并分析了液压阀在液压系统中受不规则周期力时的稳态响应，并进行了举例求解。另外还对已知液压阀振动位移规律的情况下，如何求解其振动响应进行了分析。并举例其受简谐基础激励时的振动响应进行了求解，并且用matlab得到了振动响应曲线。
