报告摘要：
In structural topology optimization under band harmonic excitation, inaccurate integration values may lead to incorrect topology optimization results. To address this problem, this work proposes an improved adaptive quadrature method and its restarting criterion. When the restarting criterion is satisfied, the subintervals divided in the previous iteration step are rolled back and reused in the subsequent integral calculation, which ensures the accuracy of the integral and effectively reduces the number of error estimations in the integral calculation. At the same time, considering that the structure topology optimization under band harmonic excitation with a non-zero starting frequency is not able to obtain a feasible engineering configuration, an optimization model with the static response of the structure as a weighted part of the objective function is introduced. The improved adaptive quadrature method will be integrated into structural topology optimization under band harmonic excitation. Three examples are given to illustrate the practicality and effectiveness of the proposed method.
