Abstract

A multibody dynamic system is the one that consists of solid bodies (rigid and flexible bodies) connected to each other by joints and/or couplings such as springs, dampers and actuators that restrict their relative displacements, including rotations. The study of multibody dynamics is the analysis of how the components of mechanisms move under the influence of forces, also known as forward dynamics. A study of the inverse multibody dynamic problems, that is, which forces are necessary to make the mechanical system move in a specific manner, is known as inverse dynamics. Motion analysis is important because product design frequently requires an understanding of how multiple moving parts interact with each other and the surrounding environment. From train locomotives and aircraft to automobiles and assembly lines, moving parts generate loads that are often difficult to predict. Complex mechanical assemblies present design challenges that require a systematic dynamic analysis to be undertaken.
