摘要
采用SAP5P程序对YZ-55A型牙轮钻机进行整机的动态特性计算和分析.结果表明,钻机合理的工作转速范围应在80～150r/min之间,在利用YZ-55型牙轮钻机的实测载荷谱的基础上,引入校正系数对YZ-55A型进行动应力计算,得到该钻机整机振型和应力-时间历程图.
Presents the dynamic characteristic analysis of YZ-55A Blast-hole Drill's structure by using SAP5P program. The result shows that the reasonable working rotation speed range should be between 80 and 150r/min. Based on the load spectrum of YA- 55 Blast-hole, the dynamic stress calculation on YZ-55A is carried out by introducing adjusting coefficient, the structure's vibration modes and strees-time histories are are presented.
