<正>本文论述了平面复链机构位移分析的虚主动构件法的基本原理,并以一个平面六杆复链机构为例,利用电子计算机,求得其位移解。 此法概念明确,步骤简单,对分析任何平面的和空间的复杂机构的位移具有普遍意义。

This paper presents a method for the position analysis of planar complex multi-loop chains. By using imaginery inputs additional to the original inputs, a complex multi-loop chain is turned into a simple multi-loop chain and the number of unknown parameters in the position analysis is greatly reduced. An example of the application of this method is given.
