摘要
为探索植物叶片各变量参数及加载载荷与其可靠性之间密切关系,采集石栗新鲜植物叶片,通过三坐标测量仪获取植物叶片的坐标数据点云,在ANSYS中建立简化的叶片有限元模型,基于蒙特卡罗法对叶片模型施加随机风载求解计算。结果表明:假如模拟次数足够多,运用ANSYS软件与蒙特卡罗相结合的随机有限元法分析植物叶片的可靠性是可行的。
In order to explore the close relationship between variable parameters of plant leaf and the reliability, a fresh plant leaf was picked and the coordinate clouding data of the plant leaf was got by the coordinate measuring machine. Then the data of the outlines and veins of plant leaf was selected and the simple model was built in ANSYS. Numerical simulation based Monte Carlo Method is carried out for the leaves affected by random wind load in the natural environment. The results indicate that the analysis of the reliability of plant leaves by ANSYS combined with the Monte Carlo method is feasible.
