Study of DCOM-Based Simulation Applied in Locomotive & Track Coupling Dynamics

Locomotive-track coupling dynamical simulation has made good achievements12. However, a problem, how to improve the simulating speed when visualization and dynamical computation are considered at the same time, is still not overcome. Here, based on existing success, we present a distributed COM technology, which is used to change the status of the present slow speed simulation. In this paper, at first, the locomotive-track dynamics system is modeled, a resolving formula is discussed, and visualization of the system is given, then the characteristic of the main integration resolving algorithm is analyzed, which is the reason of actuating the DCOM method. Secondly, we divide these resolving equations into several separated module,which is distributed in different resolving machine as a COM, and construct a distributed parallel computing environment, this method effectively reduces the computing load of the main computer and the computing speed is improved, which is the basement of real-time simulation such as virtual dynamical test of locomotive.
