【摘要】：卧式伺服液压缸常用于水平或倾斜做工,在特定工况需要输出曲线力,旋转一定的角度,需要铰接安装。为了克服伺服液压缸由于自重所引起的密封圈磨损、拉缸、泄漏等缺陷,延长液压缸的使用寿命,提出一种伺服液压缸新型支撑结构即在大型卧式重载伺服液压缸缸底端部铰接一个支反力小液压缸及外接液压系统。对这种新型结构进行受力分析,推导出该结构的动力学模型,并在MATLAB/Simulink环境进行仿真,证明该方法的合理性和可行性,将现场采集到的实验数据与其理论值进行对比来证明该方法的实用性和正确性。这种新型支撑结构为大型重载伺服液压缸及液压系统设计提供了一定的参考价值和指导意义。
[Abstract]:Horizontal servo hydraulic cylinder is often used to work horizontally or tilted. It needs to output curve force, rotate a certain angle, and need to be hinged to install in a certain working condition. In order to overcome the wear of sealing ring caused by self-weight of servo hydraulic cylinder, pull cylinder, Leakage and other defects, prolonging the service life of the hydraulic cylinder, This paper presents a new supporting structure of servo hydraulic cylinder, that is, a small hydraulic cylinder supported by counterforce and an external hydraulic system are hinged at the bottom end of a large horizontal heavy duty servo cylinder. The stress analysis of this new type of structure is carried out. The dynamic model of the structure is deduced and simulated in MATLAB/Simulink environment, which proves the rationality and feasibility of the method. The experimental data collected in the field are compared with the theoretical values to prove the practicability and correctness of the method. The new supporting structure provides a certain reference value and guiding significance for the design of large heavy-duty servo hydraulic cylinder and hydraulic system.
