Abstract
Abstract This paper presents a numerical method for solve transient analysis in vibration analysis. The dynamic model of the combat vehicle is used in this paper, A half car lumped mass dynamic model s derived. Numerical simulation is conducted using Runge Kutta fourth order method. The first thing to do is sketch the model of the object to be studied, the next is motion equation derivation, the next thing is to reduce the equations of motion that has been made to be solved by numerical methods with Runge Kutta fourth order. The stepping time in the Runge Kutta fourth order method is important role in numerical analysis, in this study using a timing which is a derivative of the maximum frequency when the vehicle is not damped. The simulation results showed that for stepping over a specified time of 0.01 s produce unstable simulation results, in contrast, using a time step of 0.001 s has provide a more stable results.
