摘要
针对图解法能较快得出结果,易于校核的优点,在研究无极速度图性质、绘制方法的基础上,给出平面几何构造分析的无极速度图法,该法可以分析平面结构在各种自由度情况下的几何构造;通过算例表明,该方法简单,易掌握;并且在利用几何不变性规则分析平面结构的几何构造失效时,分析比较方便。
In light of the merits of the graphic method that a conclusion can be reached fast and it is easy to check,here presented is a new kind of graphic method-the non-polar velocity diagram method for analyzing the geometric construction of plane struetures. The characters and drawing method of the non-polar velocity diagram are introduced. The geometric construction of plane structures in the conditions of various freedoms can be analyzed by using the new method, and the applications are illustrated with examples. The presented method is simple and easy to handle, and it is applied more conveniently in plane structures when the composing rules of geometrically unchangeable system are no longer in force.
