摘要
运用ANSYS软件中参数化语言设计与蒙特卡罗法相结合的随机有限元法,以内六角扳手为研究对象,选择扳手的多种设计参数和作用载荷为随机变量,在假定的统计分布情况下进行扳手的强度可靠性分析。结果显示,随着抽样次数的增多,输出变量DETSS的均值逐渐收敛趋于稳定,这表明运用ANSYS和蒙特卡罗法相结合的方法对扳手结构强度的可靠性分析是可行的。
The random finite element method, a combination of APDL in ANSYS and Monte Carlo method, being taken as a research method and the hexagonal spanner being taken as a research object, a reliability analysis is conducted in respect of random variables of a variety of spanner design parameters and loads. Meanwhile, this reliability analysis of spanner is carried out in the case of hypothetical statistical distribution of output parameters. The results show that the mean of output variables is gradually reaching convergence and is stabilized with the increasing sampling frequency. That indicates that the combined use of both ANSYS and the Monte Carlo method for reliability analysis of the structural strength of spanner is feasible.
