Representative Achievements A new vibration reanalysis method is firstly proposed, which has high computational efficiency in the repeated calculation of the natural frequency and mode shape of the structure. In the second, a more efficient method is proposed for calculating structural harmonic response in topology optimization problems. In the third, a reanalysis method is proposed to efficiently calculate the natural frequency and mode shape of the structure when some components need to be increased in the optimization process, that is, the degree of freedom of the corresponding finite element model is increased. Fourth, an effective calculation method is proposed to optimize the natural frequency of the structure in the topological optimization problem. This method can effectively improve the efficiency of the structure optimization on the premise of ensuring the final structure accuracy.
