摘　　要：ADAMS是使用较为广泛的多体动力学仿真软件,能够进行复杂的模型仿真计算,以求解机构的动力学问题。在ADAMS软件的实际使用中,按实际结构对模型施加运动副与驱动经常会出现冗余约束,导致模型被过约束“锁死”(locked up),以至于不能完成动力学仿真计算。采用理论计算与仿真验证相结合的方法,以动力稳定装置为例,探究了在ADAMS中产生过约束的原因,并提出了相对应的解决方法。ADAMS is a widely used multi-body dynamics simulation software,which can be used to simulate and calculate complex models to solve the dynamic problems of mechanism.In the practical use of ADAMS software,the redundant constraints are often caused by the motion pair and drive of the model according to the actual structure,which leads to the problem that the model is locked up,so that the dynamic simulation calculation cannot be completed.By combining theoretical calculation and simulation verification,take the dynamic stability device as an example,explore the causes of over constraint in ADAMS,and propose the corresponding solution to eliminate the over constraint equation.
