Optimization design method for incongruous deformation resisting structure of cabin opening of high-speed tracked vehicle

The invention relates to an optimization design method for an uncoordinated deformation resisting structure of a cabin opening of a high-speed tracked vehicle, which comprises the following steps of: acquiring a main load characteristic value which influences uncoordinated deformation of the cabin opening of a vehicle body by utilizing an actually measured pavement spectrum or a vehicle body load spectrum, and firstly, determining a mechanism based on quasi-static deformation analysis of a cabin opening finite element model added with an equivalent limit static load; preliminarily determining an optimal design scheme of the cabin opening structure by combining a topological optimization calculation result of related parameters of the cabin opening anti-inconsistent deformation design; and then the design effect is verified by analyzing the structural response of the improved vehicle body dynamic model under the action of the vibration impact excitation load, so that whether the design scheme is implemented or
