总结 本文使用矩阵结构分析 MSA 来处理多体系统的刚度分析。这种方法允许我们从每个单元的刚度属性获得结构的刚度矩阵。首先描述MSA方法，并使用L结构详细说明其应用，以便于理解。 L 结构和 6-RSS 并联机械手获得的数值和实验结果证明了该方法的有效性。
SUMMARY This paper deals with the stiffness analysis of multibody systems using the Matrix Structural Analysis—MSA. This methodology allows us to obtain the stiffness matrix of the structure from the stiffness properties of each element. First the MSA method is described and its application is detailed using an L-structure in order to make easy its understanding. Numerical and experimental results obtained for the L-structure and a 6-RSS parallel manipulator, follow to prove the validity of the methodology.
