The Lanchester Model has been widely used to explain the main features of the battle. However, its application to actual cases seems to be limited. The purpose of this study is to attempt to extend the Lanchester Model with the System Dynamics approach in order to better suit the real modern AirLand Battle case. To demonstrate how the AirLand Battle System Dynamics model works and how it provides easier ways to account for variables, normally present in real combat situations, three common tactical scenarios are employed for simulation. The results indicate that the developed model can fully describe AirLand Battle and reflect the synergy that results from the interaction of strategies and force redeployment. The proposed model, in addition, allows users to easily adjust settings when simulating different scenarios.
This study analyses the dynamic behaviour of a machine gun mounted on a four-wheeled vehicle. The entire system comprises three parts: the gun, the flexible monopod, and the vehicle. The weapon has a multirigid-body mechanism and comprises a rigid receiver, a rigid bolt, a bullet, a buffer, and a recoil spring. The vehicle model features a rigid vehicle body, suspension springs, shock absorbers, and wheels. The finite element method is used to model the flexible monopod connecting the gun and the vehicle. This study combines a computer-aided analysis of rigid-body mechanisms with finite element analysis of a flexible structure to derive the total equations of motion, incorporating the Lagrange multiplier. The total equations of motion are solved with numerical integration to simulate the transient response of the whole system. This approach can easily resolve the problem of rigid-flexible coupling effect, and promote the function of the whole system in the engineering design phase.
