摘要 在LabVIEW平台上设计了非线性振动仿真和测试分析系统.系统功能包括常用的时域、频域分析功能,还包括非线性分析所需的相轨图、Poincare图、分叉图、Lyapunov指数等模块.仿真数据可由几种方法生成,既可以在控制面板或在MATLAB节点中输入状态变量表示的函数来生成,也可以选择输入其他仿真程序生成的数据.实际测试时则从工程系统中采集数据. The functional modules of a nonlinear vibration simulation and test system based on LabVIEW are presented. The system can create many common nonlinear plots including the Poincare Map, bifurcation drawing, Lyapunov exponent figure, etc. The data can be input by real time data acquisition from an engineering vibration system or simulated by three different methods: on the control panel, using script nodes for the MATLAB language syntax in LabVIEW to execute math scripts, or from computing programs in other platform.
