Firstly this article briefly describes the technology of topology optimization. Then the design space of frame of aircraft deicing vehicle is established and the model of finite element is gained by meshing. Loads and DOF constraints are applied based on the analysis of working conditions. The results of topology optimization are attained by calculation. On the basis of aforementioned results, the analysis is made. Secondly after a brief introduction of the theory of modal analysis, the modal analysis for the aircraft deicing vehicle is made. Then topology optimization takes the maximization of the 1st mode frequency as the objective function on the basis of modal analysis. Finally, the second design is carried out according to the results of topology optimization, and a summary of the thesis is concluded.
