摘要
采用非线性弹簧接触力和非线性阻尼描述了含间隙运动副副元素的碰撞接触过程 ,以此为基础建立了含间隙平面连杆机构的动力学模型。通过大量的数值仿真 ,研究了运动副间隙对机构动态特性的影响及副元素的相对运动过程。首次指出了高速运转条件下 ,运动副副元素由于弹性变形而出现的连续变形接触现象。
This paper takes account of the boundary condition of elements of a joint with clearance when contact occur, by using the nonlinear spring damper formulation to model the resulting reaction force between the elements of clearance joint. The dynamic response of a revolute joint in a four-bar mechanism with a clearance is investigated. When the resulting equations of motion are solved numerically, they show the elements of a clearance joint keeping continuous deformation contact when the mechanism works at high speed.
