| 摘 要： | 利用有限元法对塔式起重机塔头进行了可靠性分析，克服了用传统方法分析所带来的不足。研究开发了以成本最低为目标，在结构优化设计中考虑可靠度约束的可靠性优化设计方法，省去了常规的应力约束。数值结果表明，这种方法使工程设计达到结构合理，安全又经济。

| Abstract: | In this paper, a FEM for the reliability analysis of the head of tower crane is developed, which overcomes the shortcomings of reliability analysis based on some common methods. A reliability optimal design is developed, which involves the boundary of reliability and the object of minimum cost, eliminating the common boundary of the stresses. The results show that this method makes the design reasonable in structure, safe and economical. |
