模具研配液压机同步系统的研制

Development of die spotting hydraul ic presses synchronous system

针对流体传动及控制系统中较难解决的高精度同步控制问题,提出一种比例阀与伺服阀复合控制的新型同步系统,并分析了设计方案、控制方法等问题.该系统不易形成累计的同步误差,具有高同步控制精度、高能量利用率等优点.

According to the difficult problem o f synchronous control in fluid transmission and control,put for-ward a new type of synchronous system by compound control of proportion -v alve and servo and then analyze the design scheme ,control method and other problems.It is not easy to form accumulated synchronous errors in this system.This system has many advantages such as high precision of syn chronous control,high utilization ratio of energy.
