Abstract

An automotive transmission system is a system that has the function for conversion torsion and the rapidity (rotation) from the torsion machine and it has a different rapidity to keep on to the last activator. This conversion changes the high rotation speed becomes lower, but it has more energy conversely. The highest torsion in certain machines generally occurs in a half from the limit from the machine rotation which allowed, while the vehicle needs the highest torsion start from it could be moved. The purpose of this study is to modify the accuracy and the exact transmission, so that the activator transmission which uses a pulley system (part of the automobile chassis) and belt will have a gentle rotation by activator use motor stepper with more energy in it. This machine works by having a battery to supply electricity to the motor stepper, then it is controlled by azimuth and elevation moving control so that transmission of weapon bipod will move with elevation-100 s/d 600 degrees. Azimuth moving control will be pressed so it will move the motor stepper and make the weapon move to 360 degrees. The result of the rotation of the motor will move gently and the comparison between use motor DC gearbox which not really soft at the rotation itself.

Abstract

The combat vehicles that Indonesia Army belong to most of the materials are steel, for example the armored vehicle anoa 6x6. Steel material is used as a fire protection on the vehicle, it will greatly affect the performance of the vehicle. It is caused the steel material has a high density, which is around 7750 kg/m3to 8050 kg/m3. So, with a large enough volume of the vehicle body, it will increase the burden of the vehicle. As well as the engine load will increase, and more power is needed to be able to move the vehicle. Seeing these problems, it is necessary to have a research or study on alternative materials to replace the body of a combat vehicle that can withstand fire from opposing weapons that cause personnel to be injured. In this study, experimental and simulation methods were used using the ansys application to analyze the strength of the composite material in the form of an aluminum layer that had been treated to increase the hardness value. Furthermore, it is coated with a composite material using a carbon fiber matrix of epoxy, HGM and polyurethane. The coating material is called Fiber Metal Laminate (FML), so the material used has a lighter density, the load received by the vehicle engine is lighter, and the performance of the vehicle will be more effective and efficient.
