某升降机构位移差超差问题分析与改进

Analysis and Improvement of the Displacement Difference for a Lifting Mechanism

针对某升降机构在下降过程中出现的位移差超差问题,进行了原因分析,定位于升降机构下降过程中,蓄能器放油导致两个升降缸不同步,造成位移差超出限定值。针对这一问题,提出了改进措施,并采用AMESim软件进行了仿真验证,通过产品试验进行了实物验证。试验结果表明,改进措施有效,效果良好。

Aimed at the displacement difference out-of-tolerance in the descending process of a lifting mechanism,the causes are analyzed.The two lifting cylinders are out of synchronization because of oil discharge of the accumulator during the descending process,which cause the displacement difference to exceed the limit value.In order to solve this problem,an improvement measure was proposed.Simulation verification was carried out using AMESim and physical verification was carried out through product tests.The results show that the improvement measure is effective.
