다물체 동역학 해석을 통한 구조 해석의 하중 계산법 (Load Evaluation Method for FEA through the simulation of Multi-body Dynamics)
Abstract :
When the stress on the object is calculated using finite element software, the load condition can be got by the experimental data or the used assumptions. However, it is difficult to obtain experimental data or assumtion data about the load condition in special cases. To solve this kind of problem, a system can be simulated by the multi-body dynamics. As a result, the reaction force of the body can be calculated and this dynamic load can be used in finite element software as a load condition. This paper describes how to apply the load condition in finite element software using the RecurDyn (multi-body dynamics software) and Ansys (finite element software). The system analysis is performed by using RecurDyn and then the dynamic load (reaction force of body) is applied into the Ansys. This paper describes how to apply these dynamic loads in Ansys.
