特种车辆传动产品系统建模与仿真分析

Modeling and Simulation of Special Vehicle Transmission Products System

针对目前特种车辆装配参数优化手段少导致工艺指导性需要进一步提升的现状,以特种车辆复杂传动系统为对象,应用SimulationX软件开展建模仿真分析工作,建立了典型传动产品的系统模型,包括变速器模型、液压系统模型、控制系统模型等,在此基础上,将软件自带的故障模型添加至建立的系统模型中,基于建立的系统模型及故障模型进行传动系统可靠性分析,并针对试验过程进行了模拟仿真。通过研究表明了利用SimulationX软件构建系统模型具有可行性,通过建立系统模型进行仿真可以实现传动产品性能的预测,说明在在一定程度上可以通过虚拟试验代替物理试验进行装配关键参数的优化,这将大大的节省装配参数优化的时间。

This article takes the special vehicle and its transmission product complex system as the object,applies the SimulaitonX software to carry out the modeling simulation and analysis work,established the transmission product system model and the failure model,carries on the simulation verification for the test process,uses the system the model analyzes the impact of tolerances.The research shows that it is feasible to use the system model to replace the physical model and the virtual test part to replace the physical test to optimize the key parameters in the manufacturing process,which provides a method for the analysis and optimization of the assembly process based on the digital twin technology.
