铁道车辆车轴设计可视化系统
Rolling-stock Axle Design Visualization System

为提高车轴现有算法的灵活性，基于Windows环境，以NX为平台，利用C#.net、Fortran以及C++net，通过混合编程技术集成开发了铁道车辆车轴设计可视化系统RAxleDVS（Rolling-stock Axle Design Visualization System），其中C#、Fortran、C++分别实现客户端设计以及NX接口调用、数值计算、云图显示。在车轴设计过程中，RAxleDVS分为前处理、求解计算、后处理三大功能；前处理实现参数化建模及网格划分；求解计算完成力加载、力求解、弯矩和应力的计算；后处理以线图和云图的方式显示计算结果。本系统集成了从车轴结构设计到强度校核的完整过程，对车轴的高效、可靠设计有很高的实用价值。
Under windows operation system, a system for rolling-stock axle structural design and strength check (RAxleDVS) is developed on NX platform to improve the flexibility of existing axle design algorithm. The system is developed by using C#, Fortran and C++ languages, and the user interface, numeric calculation part and nephogram part are written in C#, Fortran and C++ languages, respectively. The system consists of three parts: preprocessing module, solution module and post-process module. Meshing and parametric modeling are implemented by preprocessing module, force apply and solution are completed by preprocessing module, and post-process module displays the results by curves and nephograms. Accomplishing the whole process from structural design to strength check, the system is very practical for efficient and reliable design of rolling-stock axle
