摘要:
在起重吊装作业中常有因吊钩强度不足而导致事故发生的问题,概率有限元法能清楚地模拟实际问题的真实行为特征,利用该方法可以实现吊钩极限工况下的危险区域强度可靠性分析,并确定敏感性因素,给出可靠性分析结果.运用通用有限元分析软件,首先根据吊钩的极限载荷工况,对其进行静应力分析,确定其危险区域和最大应力值,然后利用软件提供的概率分析系统模块,根据应力-强度干涉理论,建立极限状态函数,生成概率分析文件,选用蒙特卡罗方法和拉丁抽样法对吊钩进行可靠性分析.分析结果表明,在置信度为95%时,吊钩可靠度达94.1%,其可靠度在可以接受的范围内.
Abstract:
To prevent accidents in the lifting operation because of the insufficient strength of the hook, we used finite element method to simulate the real behavior characteristics of practical problems , and realize the analysis of strength reliability of dangerous zone of hook in the limit condition by using parameter design language. Meanwhile, we confirmed the sensitive factors and provided the result of reliability analysis., According to the hook’s maximum load condition, a static stress analysis was made and the dangerous zone and maximum stress value was confirmed by using the universal finite element analysis software. Then according to the stress-strength interference theory, the limit state function was established and the probability analysis file was generated by using the probability analysis system module provided by the software. The Monte Carlo method and Latin sampling method were employed to conduct the reliability analysis of hook in this paper. The results show that the degree of reliability of hook is 94.1% when the degree of confidence is 95% ,and the degree of reliability is acceptable.
