周期性载荷 meaning in English

cyclic loading
periodic load

Alpine skis ; determination of fatigue indexes ; cyclic loading test
高山雪撬.疲劳指数的测定.周期性载荷试验
Alpine skis . determination of fatigue indexes . cyclic loading test
高山滑雪板.疲劳指数测定.周期性载荷试验
Cross - country skis ; determination of fatigue indexes ; cyclic loading test
越野雪橇.疲劳指标的测定.周期性载荷试验
Cross - country skis . determination of fatigue indexes . cyclic loading test
速度滑雪板.疲劳指数的测定.周期性载荷试验
When the load is circumferential periodicity , considering only one sector ; when the structure subjected to arbitrary load , at first , using dft technique , the complete structure is analyzed by only a series of substructures with appropriate complex constraints on its boundry with the adjacent setors
同时，对结构进行静态分析时，根据受力状态，即结构受到周期性载荷和任意载荷这两种状况，分别对其进行静态分析。当结构作用任意载荷时，利用离散傅立叶变换把整个结构的分析转化为带有复约束条件的一系列子结构的分析。
