基于管道配置的电液位置控制系统同步特性研究

针对径锻机一级先导缸电液位置控制系统同步精度低的问题,运用AMESim软件研究了第一类管道配置对径锻机一级先导缸电液位置控制系统同步特性的影响。研究发现:系统同步误差随着管道长度的增加而增大,且伴有波动现象,管道长度为3m时最大同步误差是管道长度为1m时的1.4倍;管道长度为1m时的最大同步误差为无管道时的1.1倍;管道材料的杨氏弹性模量越小,对应系统的同步误差越大。

Study on Electro-hydraulic Position Control System SynchronizingCharacteristics Based on Pipeline Configuration

Target at the problem that low synchronization precision of electro-hydraulic position control system of first level pilot cylinder in radial forging machine,utilize the AMESim software to study the influence of first class pipeline configuration on the synchronizing characteristics of electro-hydraulic position control system of first level pilot cylinder in radial forging machine.Study results show that the system synchronization error increases along with the increase of pipe length and accompanied by a wave phenomenon,the maximum synchronization error when the pipe length is 3 m is 1.4 times the maximum synchronization error when the pipe length is 1 m;the maximum synchronization error when the pipe length is 1 m is 1.1 times the maximum synchronization error when there is no pipe;the smaller the Young′s modulus of pipe material,the bigger the synchronization error of corresponding system.
