摘　　要：随着液压调平系统调平精度要求的提高,对调平结束后水平精度也有不超过一定变化范围的要求。由于油液的热涨冷缩特性、液压锁的渗漏使支腿液压缸活塞杆位移发生变化,对平台的水平度有较大的影响。针对油液的热胀冷缩、渗漏对平台水平度保持的影响进行分析,并提出减少水平度变化的改进措施。With the improvement of levelness accuracy requirements in hydraulic leveling system,the levelness accuracy does not exceed the change requirements within a certain range.Due to the thermal expansion and cold contraction characteristics of hydraulic oil,leakage of hydraulic lock,make the displacement of the piston rod of leg hydraulic cylinder change,It has a great influence on the levelness of the platform.This paper analyzes the influence of these factors on maintaining the levelness of the platform,and puts forward some improvement measures to reduce the change of levelness.
