伺服阀控液压缸对液压系统动态特性影响的仿真研究
Simulation study of the influences on dynamic characteristics of a hydraulic system with servo valve controlled hydraulic cylinder
摘要
Abstract
Servo valve control hydraulic cylinder is an important component of the hydraulic servo control system,which has sig-nificant influence on the dynamic characteristics of the system.In order to improve the dynamic performance of a steel strip ten-sion control hydraulic servo system,the mathematical models of servo valve and hydraulic cylinder are established,and the main parameters that affect the performance of servo valve controlled hydraulic cylinder are analyzed from the theoretical aspect.Then the system is studied with HyPneu software.The simulation results are in agreement with the theoretical results,the research re-sults show that the hydraulic cylinder inner diameter,friction on piston of hydraulic cylinder,oil pressure,oil elastic modulus have a certain influence on the dynamic characteristics of the system.关键词
