Launching dynamic analysis for truck mounted howitzer by using flexible multi-body techniques

Abstract

The cornerstone of this article is to examine the integration possibility between artillery weapon systems and a special purpose generic hydraulic assistance control circuit in order to decrease the generated artilleries muzzle disturbances to the minimum level. The muzzle disturbance simulation of 122 mm caliber truck-mounted howitzer during firing is carried out in different calculation methods in terms of rigid and flexible components. Different element types are employed to build the best flexible model for such weapon system. Before launching dynamic simulations, modal analysis is accomplished to validate the numerical results accuracy of the generated flexible models by comparing them with the experimental snapshots. The muzzle disturbance simulations for such weapon system are demonstrated in both bandwidth and frequencies. In addition, sensitivity analyses for different design variables which affect the firing angle are completely examined. Finally, a future upgrade expectation of fully controlled muzzle disturbances for such weapon system is established. Complete problem formulation and system stability requirements are determined to specify accurately the required hydraulic responses in the future weapon.
