Dynamics Simulation Efficiency of the Chain-drive Mechanism
On the simulation of the multi-contact constraints system, its computational efficiency is often inferior and even to solve the model in the simulation process in the crash, leading to the failure of computation. One of the reasons is the nature of the constraint is not currently involved in transient contact with the iterative calculation, so the solving matrix is large and the condition number of matrix increases, resulting in low efficiency for solving. To the efficiency of calculation , we utilize (de)active contact constraints real-timely to reduce the size of iterative calculations to improve the solution efficiency. The given method can improve computational efficiency obviously without losing solving precision for the dynamics simulation based on the chain-drive mechanism.
