侧面碰撞安全约束系统开发
工程问题：
整车侧碰仿真的结构变形如何更好地与试验结果对标？怎样的结构变形模式才能更好地保护侧面乘员安全？是否可同时进行结构和约束系统的优化？是否可以分开进行结构和约束系统的优化设计？ ……

虚拟开发阶段 Virtual Development
Benchmarking data or base model are very important. Simulation leads development supported by minimal testing.
•
测试验证阶段 Testing
Tests required to confirm simulation results and hardware performance.
