研制了一种机械式应变控制变频加载系统，用于软土的循环试验。该系统由变速驱动系统（变速电动机）和旋转/平移转换器（曲柄和曲柄轴系统）组成。它能够产生轴向应变的简谐时程，在无限数量的所需的应变水平。加载系统简单，并且可以以低成本容易地制造。通过对旧金山弗朗西斯科湾泥浆样品进行扫频测试，验证了系统的性能。
A mechanical, strain-controlled, variable frequency loading system has been developed for cyclic testing for soft soils. The system consists of a variable speed driving system (variable speed electric motor) and a rotation/translation converter (crank and crank-shaft system). It is capable of producing a simple harmonic time history of axial strain at an infinite number of desired strain levels. The loading system is simple and can be easily fabricated at low cost. Performance of the system is verified by performing frequency sweep tests on a San Francisco Bay mud specimen.
