Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0032] Such as figure 1 As shown, the multi-field coupled dynamics integration simulation analysis steps of the present invention are as follows:
[0033] 1) Establish a coupled structural equation of motion
[0034] Considering the physical model of high-speed winged missile composed of body, wing and empennage, when performing structural dynamics analysis or simulation, the mass matrix and stiffness matrix solutions are usually obtained by using the mode superposition method or branch mode method Coupled or quasi-decoupled differential equations of motion
