Launch Load Separation Design Principle of Truck-Mounted Howitzer Chassis

doi:10.12382/bgxb.2022.0098

Abstract

Abstract: Launch load transfer control is key to the lightweight and high maneuverability design of truck-mounted howitzers, and has always been a hot issue in the field of artillery research. To control launch load transfer, according to the configuration characteristics of truck-mounted howitzers, the presented work puts forward the basic principle of launch load separation design for chassis subjected to launch load, and constructs the constraint conditions for launch load separation. Based on the topological structure of a truck-mounted howitzer, its dynamic launch model is established, and the boundary conditions, the release coordination conditions as well as the constraint conditions are given. The correctness of the model is verified by comparing the calculation results and experimental data of the load and response of the key components in the launching process of the truck-mounted howitzer. In addition, through the analysis of the load on tires with different support structures and the firing stability, the results show that the load separation design for the truck-mounted howitzer can not only avoid the influence of the launch load on the chassis wheel bridge system, but also guarantee that the truck-mounted howitzer has the same reliability as the chassis. Moreover, the load separation design also plays a positive role in improving the performance of the truck-mounted howitzer, which verifies the effectiveness of the load separation principle and realizes the functional integration and performance decoupling design of the vehicle and the howitzer. The load separation design for truck-mounted howitzers realizes the requirements of a light chassis to bear the strong impact load from launch. It is an ideal method for highly mobile launch of long-range artillery.

Key words: truck-mountedhowitzer, launchloadseparation, dynamicmodel, firingstability
