摘要
本文提出了平面连杆机构运动弹性动力学(KED)分析的新模型——等厚锥形梁元。利用拉格朗日方程,推导了单元的质量矩阵和刚度矩阵,建立了系统的运动微分方程,用wilson-θ法求解其系统的动力响应,并与前人的结果作了比较,验证了模型的合理性和应用价值。
A new model of kineto-elasto dynamics analysis of plan linkage(equal thick taper-beam element)is presented in this paper.By using langengat equa- tions,mass matrix and stiffness matrix of element are derived,and deffrential equ-ation of motion of system is set up.Then,by using wilson-θ method, dynamics response of system has been given and has been compared with re- sults of pre-man,the new model proves to be reasonable and it has a great value in practice.
