摘要
以某塔式起重机事故为例,运用有限元计算的方法对实体单元模型局部进行计算,讨论刚性不足和应力集中对材料受力的影响。分析造成结构损坏的原因,并在结构上提出相应的改进措施。
One tower crane accidents were taken as example, finite element method was applied for the analysis of entity unit models. The effect of rigidity lack and stress convergence on the material was discussed. The matters leading to the structure damage were analyzed, and the corresponding improvement measures on the structure were put forward.
