文摘When designing a complex mechatronics system,such as high speed trains,it is relatively difficult to effectively simulate the entire system's dynamic behaviors because it involves multi-disciplinary subsystems.Currently,a most practical approach for multi-disciplinary simulation is interface based coupling simulation method,but it faces a twofold challenge:spatial and time unsynchronizations among multi-directional coupling simulation of subsystems.A new collaborative simulation method with spatiotemporal synchronization process control is proposed for coupling simulating a given complex mechatronics system across multiple subsystems on different platforms.The method consists of 1)a coupler-based coupling mechanisms to define the interfacing and interaction mechanisms among subsystems,and 2)a simulation process control algorithm to realize the coupling simulation in a spatiotemporal synchronized manner.The test results from a case study show that the proposed method 1)can certainly be used to simulate the sub-systems interactions under different simulation conditions in an engineering system,and 2)effectively supports multi-directional coupling simulation among multi-disciplinary subsystems.This method has been successfully applied in China high speed train design and development processes,demonstrating that it can be applied in a wide range of engineering systems design and simulation with improved efficiency and effectiveness.
