A certain type of launch vehicle cabin not only bears the weight of the launching device, but also withstands the transient impact transmitted by the chassis, which is caused by the rough road. As an intermediate link, its structure should have sufficient strength and reliability. The structural strength of this type of cabin frame is simulated and calculated by using the finite element analysis method. The impact conditions are identified to ensure that the simulation input shock conditions can cover the actual impact situation through driving experiment. The simulation results show that the structure is reliable and the structural performance meets the requirements.
