介绍的测试分析系统对常规的水工结构自振频率和动应力测试系统进行了改进．新的测试系统中，数据的采集、存储和分析均由计算机未完成，减少了测试中需要的仪器设备．特别是用应变片传感器及相应的量测系统也可得到结构的自振频率，所需测试仪器更少．给结构施加一冲击荷载，计算机通过传感器（如加速度计、应变片等）采集到结构的振动数据（如位移、应变等）并存储，之后根据测试的动应变可得到结构的前应力，对结构响应的动体移或动应变序列进行频谱分析，可得到结构的自振频率．系统中，计算机可对结构的响应进行实时监视，数据处理软件具有完善的数据图象显示和分析功能．现场实测应用比较表明该测试系统测试分析结果可靠，具有较好的精度，简单实用，可用于各种水利工程动力检测．
The introduced test analysis system improves the conventional natural frequency and dynamic stress test system for hydraulic structures. The new test system, the data collection, storage and analysis by the computer is not completed, reducing the test equipment needed. In particular, with the strain gauge sensor and the corresponding measurement system can also get the natural frequency of the structure, the required test equipment less. An impact load is applied to the structure. The computer collects and stores structural vibration data (such as displacement, strain, etc.) through sensors (such as accelerometers, strain gauges, etc.) and stores the prestress of the structure according to the tested dynamic strain. In response to the dynamic displacement or dynamic strain sequence spectrum analysis, the natural frequency of the structure can be obtained. System, the computer can respond to the structure of real-time monitoring, data processing software has a complete data image display and analysis capabilities. Field comparison and application shows that the test system test results are reliable, with good accuracy, simple and practical, can be used for a variety of hydraulic engineering dynamic testing.
