“…The present multibody system dynamics methods mainly include Newton-Euler vector mechanical method, Jourdam principle, Lagrange method, Gauss principle, Transfer matrix method of multibody system, and so on [15][16][17][18][19] . Taking a self-propelled artillery and tank as examples, applying the transfer matrix method for multibody system (MSTMM) and the automatic deduction theorem of overall transfer equation 20,21 , the system dynamics equations of the self-propelled artillery and tank were derived in ref.…”

Abstract-The initial disturbance of the projectile is the premier factor that takes effect on the marching fire accuracy of the conventional weapon, which depends on the projectile firing process of the conventional weapon. In this paper, the theory of projectile firing process of the conventional weapon during marching fire was studied. Combining the projetile motion equations in gun tube with the system dynamics equations which can be obtained by various multibody system dynamics methods, the motion of the projectile in barrel and the initial disturbance of the projectile can be exactly simulated. This work provides both theoretical foundation and simulation approaches for improving the marching fire accuracy of the conventional weapon.

“…This led to the development of general purpose computer programs for MSA. However, the early versions were limited to two-dimensional systems with open tree configurations (where a cut in any component separates the system in half) [48]. This limited the application to systems which are relatively simple.…”

Hamilton's Law is derived in weak form for slender beams with closed cross sections. The result is discretized with mixed space-time finite elements to yield a system of nonlinear, algebraic equations. An algorithm is proposed for solving these equations using unconstrained optimization techniques, obtaining steady-state and time accurate solutions for problems of structural dynamics. This technique provides accurate solutions for nonlinear static and steady-state problems including the cantilevered elastica and flatwise rotation of beams. Modal analysis of beams and rods is investigated to accurately determine fundamental frequencies of vibration, and the simulation of simple maneuvers is demonstrated.iv
