经典弹簧质量的车桥耦合程序，ansys平台编写(Vehicle bridge coupling program with classical spring mass, written on ANSYS platform)

可以计算临界转速，书上的一个例子，可以看看(Calculating Critical Speed)

说明：  基于matpower 的最小网损最优潮流解(Optimal power flow solution with minimum network loss based on MatPower)

对板状体重力异常进行反演得到板状体的各种特征(Weight force on the plate-like anomaly inversion of the various features of the plate-like body)

说明：  三层框架白噪声激励模态分析，激励频段0-100hz(Modal Analysis of White Noise Excitation for Three-storey Frame)

说明：  冲床应用行业检修使用的PLC程序，包含了工艺上的完整过程，其他冲床的程序也都是类似的(The PLC program used in the maintenance of punch application industry includes the complete process of technology, and other punch programs are similar.)

通过仿真可以进一步了解悬架性能，很具有使用意义(The performance of the suspension can be further understood through the simulation)

The power electronic drive controls the rate of induction motor by V/F method.
