中文摘要：

在通过仿真计算获取并联机床势能分布规律的基础上,设计了机床的平衡机构。以平衡效果最佳为目标函数,通过优化计算,得出了该平衡装置的结构参数值。平衡后,机床各驱动关节的最大驱动力只有平衡前的13.7%,平衡效果很好。该平衡方案结构简单,平衡效果好,可为类似结构机床的平衡提供参照。

英文摘要：

The distribution law of a parallel machine’s potential energy was simulated and calculated.According to this,a balancing mechanism of the machine was designed.The structure parameters of the balancing mechanism were optimized.The max force of driving chains remains only 13.7% after balancing.So the balancing effect can be considered as good.This balancing mechanism is very simply,easy to actualize and effect well.It can be as a reference to other similar machines’ balancing.
