摘要
基于兼有矢量力学与分析力学的优点、在多体系统问题分析中有着广泛应用前景的凯恩方法,建立了链式多体系统动态特性分析模型,并进一步给出了求解其(铰)接点约束力的计算方法。最后,利用多体系统离散时间传递矩阵法和经典力学方法对计算模型的有效性和准确性进行了验证。相关结果对基于Kane方法开展多体系统动力特性分析具有参考意义。
Based on the Kane method with the advantages of both vector and analytical mechanics and the wide application prospects in the analysis of multibody system problems, an analytical model for evaluating the dynamics of the chained multibody system was established in this paper. Furthermore, the method to determine the joint force in the system was provided. Finally, the validity and accuracy of the proposed model were verified by using the discrete time transfer matrix method of multibody system and the classical mechanics method. Relevant results provide valuable reference for the analysis of the dynamics of multibody system based on the Kane method.
