| Abstract: |
| The high efficiency,high accuracy and high performance numerical integration algorithms are hot tops in the field of multibody system dynamics.Direct numerical integration methods which solve the structural dynamics equation are applied to solve the DAEs in this paper.Based on the SiPESC platform and the open simulation algorithm software for multibody system dynamics,comparison study of Newmark method,HHT-I3 method, Generalized α method,Bathe method and Zu Chongzi Symplectic method is made.By using the compound pendulum and the rigid-flexible double pendulum examples,this paper studied the relationship between parameters and numerical dissipative of different algorithms.For solving the high-low frequency coupled and high-speed rotation of the gyro problems,the system can be accurately simulated by the non-dissipative Newmark method and Zu Chongzi Symplectic method. |
