| 摘 要： | 摘 要：应用多刚体动力学理论在 ADAMS 软件中对复杂模型进行简化建模与仿真，解决 复杂模型在 ADAMS 中建模过程繁琐、仿真过程计算效率低等问题。首先对简化建模方法的多 刚体动力学理论进行了分析；然后提出了基于 ADAMS 简化建模的具体方法，着重研究了使原 模型和简化模型中心主转动惯量、中心惯量主轴连体基方向相同的数学方法；最后，将该简化 建模方法应用到过山车单车模型上，并对仿真结果进行对比分析。结果显示基于 ADAMS 的多 刚体动力学简化过山车模型与原模型的仿真效果基本相同。该简化建模方法能有效提高复杂模 型在 ADAMS 中的建模效率和仿真的计算效率。

| Abstract: | Abstract: In ADAMS software, multi-rigid-body dynamics theory is applied to simplify the modeling and simulation of complex models, which is used to solve the complicated modeling process in ADAMS and the low computational efficiency of the simulation process. Firstly, the multi-rigid body dynamics of the simplified modeling method is analyzed. Then the specific procedure of simplified modeling based on ADAMS is put forward. The present study attaches great importance to a mathematical method that enables the central principal moment of inertia and the principal axis of central inertia of the original model and the simplified model to be of the same orientation. Finally, the simplified modeling method is applied to the roller coaster bicycle model, and the simulation results are compared and analyzed. The simulation results show that the simplified dynamic roller coaster model based on ADAMS is basically the same as the original model. This simplified modeling method can effectively improve the modeling efficiency of complex models in ADAMS and the computational efficiency of simulation. |
