Response of two DOF weapon system structure mounted on four wheel vehicle

Numerical simulation of vibration amplitude is used in this research to determined vibration phenomenon in weapon vehicle mounting. Based on the simulation result with Runge Kutta fourth order method, it has result amplitude value with Magneto Rheological (MR) damper in electric variations (0,3 A, 0,5 A and 0,9 A) reduced. The remaining vibration due to a single shot, gives different phenomenon on each of three axes (angle deviation, x direction dislocation, and y direction dislocation) which are the angle deviation will stop at the moment at 2.5 seconds after the shot, the motion dislocation due to the vibration of the x direction, will start to stop at 1.5 seconds after single shot and the left over vibration movement will start to stop at 5 seconds after single shot. Based on the result, the amplitude of weapon mounting can be reduced by Magneto Rheological (MR). However, the next research, this design can be optimized to make smaller to the weapon vehicle dislocation.
