现代结构试验除静力试验外还要求作动力试验,例如模拟地震的试验。这些试验不仅要求加载准确、稳定,而且要求荷载能按一定的函数关系加载。采用电液伺服试验设备能满足这一要求。这种试验设备过去主要从国外购
Modern structural tests require dynamic tests in addition to static tests, such as those that simulate earthquakes. These tests not only require accurate and stable loading, but also require the load to be loaded in a certain functional relationship. The use of electro-hydraulic servo test equipment can meet this requirement. This test equipment was mainly purchased from abroad
