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.

“…Especially, the orthogonality conditions of the system are obtained by constructing the augmented eigenvector and augmented operator, realizing the exact analysis of the dynamics response of MS (Rui et al, 2003). This method has been applied in the fields of the multiple launch rocket system (MLRS) (Tang et al, 2016), tanks (Lui et al, 2016), self-propelled guns (Yu and Rui, 2014), and missile launch vehicles (Wang et al, 2018) and so on.…”

In this study, the transfer matrix method for multibody systems is used to study the vibration characteristics of a tracked vehicle system. The transfer matrix method has the advantages of not needing the global dynamics equations of the system, low order of system matrices, and fast dynamics computation speed. According to the solution process of vibration characteristics, a detailed dynamics model considering the rigid–flexible coupling effect is developed to describe the structural relationship of the tracked vehicle system. Then, a topology figure for representing the transfer direction of the dynamics model is proposed to derive the overall transfer equation of the system. Dynamics equations governing the motion of the system and rocket are given. Next, through comparisons of the simulation and relevant experiments, the validity and correctness of the proposed method are verified. Based on this, the coupling dynamics responses of the system with different firing orders and firing intervals are simulated and analyzed, which shows that the firing order and interval have great influences on the vibration of the system. In this case, with the adaptive genetic algorithm, a multivariable optimization method is proposed. The optimization results show that the vibration is greatly reduced by using the optimized scheme.

Abstract-The main issue addressed in this article is the lays out of truck mounted howitzer free vibration theory as a continuous interconnected multi-body rigid model in spatial coordinates. The mathematical modeling is developed by the method of the first kind of Lagrange's equations based on the weapon system discretization techniques. Searching for the eigen vibration characteristics, the characteristic equation is solved based on the derived mathematical model. This simulation numerical result is validated by certain comparative experimental works. Finally, the sensitivity analysis by using random optimization theory is applied on the simulation model in order to find the weapon system optimal design layout. This study shows a new spatial investigation applied on truck mounted howitzer. In addition, the sensitivity analysis compels the designer to identify the critical variables affect the vibration behavior of this artilary weapon system.
