This paper expounds a method of realizing animated display of structure model by computer animation at the request of test model analysis.
根据实验模态分析的需要，论述用计算机动画实现结构模态分析动画显示方法。
Taking a prototype light rail car with aluminum alloy car-body for example, the test model analysis is carried out. The test results show that the prototype car has good dynamic characteristics.
针对一台铝合金车体的轻轨样车，进行了试验模态分析，通过试验说明了该样车具有良好的动态特性。
For instance, if the requirements analyst also helps create the analysis model or the test model, he or she will be much busier beyond the requirements work for the iteration.
例如，如果需求分析人员也能够帮助创建分析模型或测试模型，他或她将比处理迭代的需求工作更加忙碌。
