This report covers the development of a moving target system for when police and military practice close quarter combat in urban environments. The ultimate goal is to simulate a realistic combat situation with moving enemy targets.
The main emphasis has been placed on obtaining a mechanical functional virtual prototype in a CAD environment. Prototype electronics will be constructed by another party and is not included in this report. The project has been performed at the Department of Mechanical Engineering. Blekinge Institute of Technology in Karlskrona Sweden, in collaboration with SALVATOR AB in Årjäng Sweden.
The common moving target system used in the military today, are targets that travel on a designated path, often a steel rail. Today these targets are mostly aimed for target practice for larger vehicles such as armed combat vehicles and tanks and are very large, heavy and not suitable for urban combat purposes.
In the principle design stage, the project was divided into two sub projects. A number of ideas for the wagons drive system and the rail construction were drawn. After a discussion with SALVATOR AB the most appropriate idea for each were chosen for primary design development.
Concept C was chosen in the primary design stage and consists of an electric motor with corresponding gear and belt pulley. With synchronous belt and pulleys on the front and rear axle equal amounts of torque are applied at the wheels. The construction is simple, proven technology and fairly inexpensive to produce.
In the primary design stage further development of the system was done by building around the belt drive system chosen in the principal stage. THe end result was a complete virtual mechanical prototype of a moving target system designed to be easily assembled before target practice and easily dismantled after target practice.
