摘要
研究带式输送机的运行过程中避免共振问题·建立了将输送带作为正交各向异性矩形薄板输送带横截面上的自由振动方程 ,导出了输送带为平形、V形和槽形情况下的SFSF ,SCSF ,SCSC三种边界的固有频率计算式 ,编写了基于搜索方法的计算程序 ,用该程序可以计算出上述三种边界条件的所有固有频率·在此基础上给出了带式输送机应采用减小托辊间距和增大托辊直径的避免共振的设计方法 ,并用此方法对实际的长距离带式输送机进行了避免共振设计 ,在应用中避免了共振的发生·
The method to avoid the belt resonance was studied in the course of the belt conveyor operation. The free vibration equation of the belt cross section was established regarding the belt as the orthotoropy rectangle sheet. The natural frequency computation experssion was deduced in belt boundary conditions SFSF,SFSC and SCSC for the plane belt,V shape belt and traugh shape belt,respectively. The calculating program basied on the searching method was compiled. The program can work out any nature frequency of the above three boundary conditions. A design method of avoiding belt resonance through increasing the idler diameter and decreasing the space between them was offered. An actual long distance belt conveyor was designed by this means,and the belt resonance of the conveyor was avoided in service.
