摘要
In this paper, the modal analysis of an air conditioner outdoor unit is carried out and the simulation results are compared with the experimental results to verify its accuracy. A separate structural optimization analysis is performed for the top plate, and the compression bars of the top plate are changed from transverse to vertical placement.The simulation results show that the natural frequency and stiffness of the top plate are improved. Under the premise of vertical placement of the compression bars, a three-factor, three-level orthogonal test is conducted to find the optimal combination of low-order natural frequency and high-order natural frequency in the given range.
