为提高基于变密度法的拓扑优化模型的迭代速度,将模型中的极限移动常数,改进为随单元密度变动的变量.结果表明:改进后,在目标函数变动微小的情况下,极大地提高了模型的迭代速率.可见此种方法,有效地改进了拓扑优化模型,具有可行性.
Improvement of Moving Limit Constant for Continuum Topology Optimization Based on Variable Density Method
In order to improve the iteration speed of the topology optimization model based on the vari-able density method,the limit moving constant in the model is improved to a variable that varies with the element density.The results show that after improvement,the iteration rate of the model is greatly improved under the condition that the objective function changes little.It can be seen that this method effectively im-proves the topology optimization model and is feasible.
