ModalVIEW is made of Modal and VIEW, which is a standard software platform for modal testing and analysis launched by Shanghai HQSignal Technologies Co.,Ltd. With DSA (dynamic signal acquisition) hardware combined, ModalVIEW software platform can easily finish a whole testing task. The complete process contains a lot of steps: data acquisition, signal processing, FRF estimate, three-dimensional modeling, ODS, modal analysis, modal shape analysis and reports generation. ModalVIEW software is developed with NI's graphical programming language - LabVIEW and integrated with powerful modal analysis functions, which help to carry out a single reference point or many reference points experiments, and then identify the modal parameters, by the global optimal situation. Advanced experiment modal analysis use poly-reference lest square complex frequency (LSCF) and stabilization plot in SIMO or MIMO modal experiment, which can identify dense mode, conjugate mode and re-root mode.

翻译：ModalVIEW由Modal和VIEW组成，译为模态视窗，是上海宏勤科技有限公司倡导的模态测试与分析的标准软件平台。结合动态信号采集硬件，ModalVIEW软件平台能够轻易完成从数据采集、信号处理、频响函数估计、三维建模、ODS、模态分析、振型相关分析和报告生成等任务。ModalVIEW软件使用NI公司图形化编程语言LabVIEW开发而成，集成了强大的模态分析功能，能够进行单参考点或多参考点的全局最优拟合识别模态，ModalVIEW的高级模态分析方法使用多参考最小平方复频率(LSCF)稳态图法，能准确识别密集模态、共轭模态和重根模态。
