And based on the consideration of the impacts of the drum end plate , surface rope slot and quality change of the wire ropes , the paper has deduced the theory calculation formula of the drum stability
同时，基于该结论在综合考虑卷筒端板、表面绳槽和钢丝绳变质量等因素的影响，利用薄壳武汉理工大学博士学位论文力学推导出了卷筒稳定性理论计算公式。
On the basis of mode experiment of the drums , the paper analyzes the impacts of the drum end and the gradual wind of the wire ropes on the drum strength . and also on the basis of the analysis of the data of the drum mode experiment , the paper presents the research conclusion that unstability mostly occurs where drums are fully wound with wire ropes
在进行卷筒模态试验的基础上，分析了卷筒端板和钢丝绳逐步卷绕过程对卷筒刚度的影响关系，在对大量的卷筒模态试验数据分析归纳的基础上，给出了钢丝绳全部绕满卷筒是最容易发生失稳的研究结论。
