摘要
本文根据力的线性迭加原理,建立了计及摩擦的平面机构的力分析数学模型;并采用逐步逼近方法,求机构的真实运动副反力及平衡力。文中给出的两个实例说明,只需若干次迭代计算,即可得到真实解。
On the principle of linear superposition of forces,a model for force analysis concerned with planar mechanism invotving friction is proposed.Counterforce and balance force in real kinematic pair are found by step-by-step approximation.Two examples given in the article show that satisfactory solution can be obtained afted a few iterative operations.
