Simulating Weapon Live Fire
For the development of reliable accessories
Overview
Re:Test, Inc. has been developing a shock amplifier to simulate the live firing of small arms on accessories since 2005. Used by the US Army, US Marines, US Navy , US Special Operations, and many accessory manufactures, the fourth generation weapon recoil shock simulator can reproduce Shock Response Spectra (SRS) to MIL STD 810H. The weapon shock simulator reproduces live fire for a wide range of rifles, such as SDMR, SCAR Heavy (Mk17), M4 (M4A1), and .50 Cal (WinMag), in addition to handguns, grenade launchers, recoilless guns, belt-fed crew-served machine guns, etc, each with their unique signatures in the time and frequency domains. It can also be integrated with autocollimators and can operate in an environmental chamber from -40C to +55C.
The fourth generation unit (GEN 4), sold by Re:Test as a standard product, was developed using non-linear explicit dynamic FEA modeling. It is built to maximize stiffness and minimize weight, for tests to 20kHz. It mounts on either a slip table of an electrodynamic shaker (WSS-VT), or a bench exciter (WSS-TB), and recreates the measured weapon shock profiles for fully automatic, semi automatic and bolt-action firing. A complete 20,000 round test can be completed in an hour. This programmable fixture closely reproduces Shock Response Spectra (SRS) and the time signature on small arms accessories. A paper on the first generation system that was developed for Bruel and Kjaer was presented at the SAVIAC 76th Shock and Vibration Symposium. The system was originally developed in conjunction with NAVSEA in Crane Indiana for Special Operations forces, and refined through work with the US Army in Picatinny. The system has also been sold to the Marines in Quantico and many vendors of weapon accessories.
Use this system for simulating weapon live fire on accessories (e.g. rifle scope testing)
