用无极速度图法确定复杂平面刚体体系的虚位移关系

To apply the non-polar velocity-diagram method determines the relations of the imaginary displacements of complicated planer rigid-body system

应用无极速度图的性质,给出确定复杂平面刚体体系虚位移关系的新方法,即通过作绘制无极速度图来确定这种刚体体系的虚位移关系。算例表明:该方法简单,容易掌握;为确定复杂平面刚体体系虚位移关系在方法上提供了一个新途径。

Applying the characters of the non-polar velocity diagram,this paper gives a new way to determine the relations of the imaginary displacements of complicated planer rigid-body system,pass through drawing the non-polar velocity diagram to determine the relations of the imaginary displacements of this rigid-body system.By means of computing it makes clear that this way is simple and easy to handle;and moreover it brings about a new way to determine the imaginary displacements of complicated planer rigid-body system.
