Coupling of Multibody Dynamics & FEA for Real World Simulation

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Multibody dynamic analysis is important because product design frequently requires an understanding of how multiple moving parts interact with each other and their environment. From automobiles and aircraft to washing machines and assembly lines - moving parts generate loads that are often difficult to predict. Complex mechanical assemblies present design challenges that require a dynamic system-level analysis to be met. Accurate modeling can require representations of various types of components, like electronic controls systems and compliant parts and connections, as well as complicated physical phenomena like vibration, friction and noise. MBD analysis enables us to meet these challenges by quickly evaluating and improving designs for important characteristics like performance, safety and comfort.

Advanced multibody dynamics analysis enable our engineers to simulate and test virtual prototypes of mechanical systems in a fraction of the time and cost required for physical build and test. A multibody dynamics (MBD) system is one that consists of solid bodies, or links, that are connected to each other by joints that restrict their relative motion. The study of MBD is the analysis of how mechanism systems move under the influence of forces, also known as forward dynamics. A study of the inverse problem, i.e. what forces are necessary to make the mechanical system move in a specific manner is known as inverse dynamics.
