A model experiment is made on an actual floating slab track , and the vibration transfer property of this track under three different frequencies of impact load is mainly tested 对浮置板进行了1 : 1模型试验,主要测试了浮置板在3种不同频率冲击载荷作用下的振动传递特性。
Finally finding that there are two reasons that cause vibration of pipe and noise . the one is the vibration of pump which transfers to pipe and stimulates the vibration of pipe . the second is the stimulating frequency of pulsating water is coherent with the natural frequency of pipe 最后得出管道的振动主要是由于两个原因,一是泵的机械振动传递给管道,引起管道的振动;二是由于水流的脉动激励频率与系统的固有频率相吻合,引起管道的共振发声。
