[0063] (3) Nest the Newmark integral and the chord intercept method, consider the excitation change caused by the instantaneous contact state change when solving the dynamic response, and realize the "excitation-response-feedback" phase closed-loop analysis process. The specific implementation method is:
[0064] 1) For the dynamic differential equations such as formula (7), the initial meshing stiffness and comprehensive meshing error are given to form the initial value of the total excitation load vector F 0 , while giving the initial value of displacement X 0 , the initial value of speed And calculate the initial value of acceleration
[0065]
[0066] 2) Select the integration step size Δt, Newmark integration parameters α, β, and calculate the integration constant (β≥0.5 and α≥0.25(0.5+β) 2 )
[0067]
[0068] 3) Form the stiffness matrix K, mass matrix M, and damping matrix C at time t+Δt, and calculate the payload at time t+Δt:
