摘　　要：单轮对滚动试验台是模拟轮轨关系多项复杂性能试验的高精度试验系统,轨道车辆轮轨黏着-蠕滑特性受多种变量综合作用影响,试验过程复杂、设计难度大、试验结果不稳定。该文研发一种滚动基于Unity3D和UM联合仿真的滚动试验台虚拟试验系统。该系统中单轮对滚动试验台动力学仿真模型通过UM建立,应用Unity3D建立虚拟仿真环境,利用MATLAB、C#完成数据的处理与传输,在虚拟环境下设计并实现多变量作用的滚动试验台黏着-蠕滑性能虚拟试验。结果表明,该系统不仅可实现多变量作用的黏着-蠕滑特性试验设计和实验结果分析,且交互性好、试验沉浸感强,能模拟多项重要的性能试验,从而降低试验成本。The single wheel-to-rolling test bench is a high-precision test system for simulating multiple complex performance tests of wheel-rail interaction. The adhesion-creep characteristics of rail vehicles are affected by multiple variables. The test process is complex, the design is difficult, and the test results are unstable. In consideration of the above factors, this paper has developed a virtual test system for rolling test bench based on Unity3 D and UM combined simulation. The dynamic simulation model of the wheel-to-rolling test bench in the system is established by UM, the virtual simulation environment is established by Unity3D, and the data processing and transmission are completed by MATLAB and C#. The virtual test of adhesion-creep performance of rolling test bench with multivariable actions is designed and realized in virtual environment. The results show that the system can not only realize the multivariable adhesion-creep characteristic test design and experimental result analysis, but also has good interactivity and strong test immersion, which can simulate many important performance tests, thus reducing the test cost.
