Product Details
High Stiffness Low Mass
The shock simulator is made using a friction welded honeycomb structure manufactured from high performance materials
Dynamic Analysis
Explicit non-linear dynamic analysis was used to develop the GEN-4 fixture and test simulation strategies. The model includes the viscoelastic properties of the custom made elastomers, bush snubbing, preloading and friction coefficients of fasteners, to provide a complete picture of the performance of the system to 20kHz in all degrees of freedom.
Electrodynamic Shaker for the WSS-VT
Re:Test can optionally supply you with the electrodynamic shaker. A powerful general purpose tool that can be used for all your MIL STD 810 tests
Bench Exciter for the WSS-TB
If you don't want or need to invest in a vibration test facility, Re:Test can build a self-contained dedicated bench mount system with it's own optional sound chamber
Benefits
- Firing rate: In fully automatic mode, the Re:Test system can test at 600 rounds per minute
- Shock accuracy: Each simulated round is two shocks, one for bolt closure and one for the pyrotechnic event, each shock can be tuned separately
- Standard compliance: The system meets MIL Std 810H Method 517.3 Proc III for pyrotechnic shock simulation
- Programmability: It is possible to simulate a broad range of weapons: rifles (M4,Mk17, SDMR, etc.), grenade launchers, crew served weapons, and hand guns (slide simulation optional).
- Multiple sights: The system can test up to four accessories at at time, depending on weight, size and configuration
- Integration with an autocollimator: The mounts are horizontal, and so it is easy to add measurement devices to check for bore-sight alignment
- Multiple systems: Customers who purchased a system from us have come back for more, and many customers have replaced their systems from other vendors
- Endorsed by the US Military: The US Special Operations (SOPMOD) is actively working on standardizing on the Re:Test system, and asking their vendors to acquire this capability. The system is also used by the Army, Marines, and Navy
- Failure Correlation: Live fire failures have been reproduced on our system within a few hundred rounds
- HALT Tests: It is possible to use the system to over shock the DUT to test for design weaknesses. The failure modes identified with this test method are often missed on the range, but reproduced in combat situations
- Flexibility: The shaker that comes with the WSS-VT can be used for a broad range of MIL STD 810 testing (additional software may be needed)
- Low Maintenance cost: Under normal usage, the fixture only requires a bushing change every 24 months. Costs are less than $1,000
Product Comparison
Shaker (WSS-VT) vs Bench System (WSS-TB)
The WSS-VT system provides you with the flexibility to perform Weapon Shock Simulation and a host of other shock and vibration tests. However it requires infrastructure such as an ED shaker, sound room, and ductwork. Our WSS-TB system provides everything you need in one stand-alone turn-key press-button package. It is also capable of meeting your most demanding weapon shock tests
