摘要
静液压调平系统作为电动平台车的重要组成部分,其调平精度直接影响整机的工作性能.为设计具备高调平精度的静液压调平系统,对调平系统调平机理进行分析,得出影响调平误差的主要因素为系统中各铰接点位置.利用ADAMS软件建立调平系统的参数化模型,以臂架变幅过程中,吊篮平台调平误差最小为优化目标,对各铰接点位置进行优化计算.根据计算结果设计电动平台车样机的调平系统,并对其调平误差进行试验测试,测试结果表明,该调平系统具备较高的调平精度,该优化方法能为工程应用中静液压调平系统的设计提供指导.
The static hydraulic leveling system is one of the important working systems of electric platform,and its leveling accuracy directly affects the performance of the whole machine.For the purpose of designing a leveling system with high leveling accuracy,the leveling mechanism was analyzed and the main factors affecting the leveling error are the positions of the hinge points in the system.Using ADAMS to set up the parameterized model of the leveling system,and by optimizing the position of each hinge point,the leveling error was minimized.According to the optimization results,the leveling system of the prototype of electric platform was designed and its leveling error was tested.The test results showed that the leveling system has high leveling accuracy.This optimization method can provide guidance for the design of static hydraulic leveling system in engineering.
