摘要
阐述了多体系统动力学理论的研究背景,指出了多种传统的柔性多体系统动力学研究方法的不足.系统地从4个方面回顾了柔性多体系统动力学绝对节点坐标方法诞生十几年以来的研究进展,即:单元研究进展、系统动力学方程求解数值算法研究进展、非线性材料多体系统动力学研究进展以及相关的应用研究进展.最后提出了值得进一步研究的问题.
Firstly,the research background of the multibody system dynamics theory is presented and shortcomings of the conventional methods for investigating flexible multibody dynamics are illustrated.Secondly, the advances in the absolute nodal coordinate method for the flexible multibody dynamics research over the last ten years are systematically reviewed in terms of the following four aspects,i.e.the advances in the element researches,the numerical algorithm researches,the researches on the dynamics of multibody systems with nonlinear materials and the researches of corresponding applications.Finally,key topics for further research are pointed out.
