Research on Dynamic Modeling and Simulation of Truck-Mounted Howitzer Under Different Road Surface and Vehicle Speed Conditions

Truck-Mounted Howitzer has outstanding advantages such as a high level of information technology, good tactical mobility, and strong comprehensive combat capabilities, playing an important role in modern warfare. Different road surfaces and vehicle speeds seriously affect the off-road performance of Truck-Mounted Howitzer. To study the dynamic characteristics of the Truck-Mounted Howitzer under different working conditions, this paper establishes a three-dimensional model and a driving dynamic model of the Truck-Mounted Howitzer. Dynamic simulation analysis is carried out using SOLIDWORKS Motion software to obtain the dynamic characteristics of typical parts of the vehicle body under different road surfaces and vehicle speeds, and its ride comfort is evaluated. The accuracy of the simulation results is verified through comparison with experimental data. The research in this article will provide a reference for the optimization design of dynamic parameters of Truck-Mounted Howitzer.
