A Case Study of Mechatronic System Simulation: Forklift Electric Control

It is very difficult to simulate the realistic nonlinear dynamics model with an electrical motor with suitable control system. Recently in vehicle system design area it becomes more important for greenhouse gas emissions in the real world. This difficulties mainly exists in the time synchronize during the simulation between the mechanical field and the electrical field which should be combined into only one time integrator. This study proposes the integration approach to simulate the nonlinear system of mechanical vehicle modeling and block/script modeling for electrical control system by using an example study of forklift electric vehicle. In the interdisciplinary framework of RecurDyn and CoLink simulation environment, both tools are simultaneously analyzed in the same integrator. For demonstration of the proposed approach, fifteen degree-of-freedom multi-body model electric forklift vehicle and a Permanent Magnet Synchronous Motor (PMSM) and controllers are represented.
