对软管输送系统进行了有限元动力学模态分析,确定了1000m钴结壳中试输送系统和5000m深海采矿输送系统的频率特性。分析可知,当海浪频率处于输送系统共振频率时,管道上端随上下结点反力的谐响应值很大,将对系统产生破坏作用。 Finite element dynamic modal analysis of the hose delivery system was carried out to determine the frequency characteristics of 1000m cobalt crust pilot transportation system and 5000m deep sea mining and conveying system. The analysis shows that when the wave frequency is at the resonant frequency of the transmission system, the harmonic response value of the upper end of the pipeline with the upper and lower nodes is very large, which will have a damaging effect on the system.
