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.
