提出一种新的加载区域设置方法——面嵌入式加载区域设置方法,阐述其设置原理和操作步骤,并与现有的加载区域设置方法进行比较,最后进行实验验证。研究结果表明:面嵌入式加载区域设置方法所得加载区域可以更好地拟合实际问题中的光斑形状和大小,其精确性不以牺牲零件模型网格质量为代价,同时,该方法在多点冲击中可以通过加载区域的平移及复制实现多个冲击面加载,大大缩短建模过程中的加载区域设置时间,提高建模效率及模拟精度,是一种高效的精密加载区域设置方法。

In this study, a novel loading set, the set of loading region based on embedded surface, is implemented using the ABAQUS finite element package. When determining the parameters and operations, a comparison is made among the current loading sets, validating the effects of these on the resulting solution. According to our investigations, the loading set based on embedded surface possesses high efficiency. This technique has the ability to predict loads with precision, increasing the efficiency of the loading set under conditions where target elements are of high quality.
