Handgun mechanisms analysis

In this paper, experimental and computer aided methods are used in order to simulate the dynamic behavior of a 9 mm handgun when fire. As known, firing process is a complex phenomenon which involves cap percussion, powder burning, bullet movement down the gun barrel and it's propulsion on the trajectory. An accurate and secure shooting needs a very fine control of all these processes. Also, the handgun mechanisms movements are in standing to influence drastically the fire precision. For these purposes we analyzed some particular aspects of a handgun dynamic, using high level CAD system Solid Works, DAQ systems, B&K signal acquisition and processing device Pulse 3560D and other testing devices developed in our laboratory.
