Abstract

Military vehicles are designed for very harsh conditions where they lose some of their efficiency. In order to maintain the efficiency of military vehicles and accompanying equipment, various designs are made that must be cost-effective. The challenge that exists is how to install a shooting range on a military vehicle and use it while moving in such a way that the shooting accuracy is acceptable. The existing stabilizer technologies are very expensive and are not economical compared to the value of cars and weapons. Therefore, passive stabilization method using gyroscopic effect should be adopted. In this method, a large flywheel with high rotational speed is used. The basic condition of using this method is to determine the number of flywheels and the number of frames used for the connection between the flywheel and the driver. In this research, according to the environmental conditions, a new model of aircraft frames and wheels is presented. This model has the ability to resist rotational stimulation in two directions. Its appropriate Lagrangian equation has been derived. After that, the main challenge is to calculate the tolerance threshold of applied stimuli. The laboratory model to solve this problem and the numerical simulation results are presented. At the end, suggestions for continuing research aimed at dealing with provocations in other directions, especially displacement, are presented.
