WSMR maintains an extensive array of equipment available for shock testing. All shock tests can be remotely controlled to accommodate explosive and hazardous test items.
Shock Testing Using Electrodynamic Exciters - Electrodynamic exciters can be used to produce classical pulses (half-sine, saw-tooth, trapezoidal) and complex pulses using shock synthesis techniques. Repetitive transient and wide-band random with mixed shock pulses (transient) can also be produced.
Shock Machines - Shock tests which require classical high peak accelerations or large velocity changes can be accommodated on shock test machines. All shock test machines can be configured to provide half-sine, terminal peak saw-tooth, or square wave shock pulses. Three shock machines are available and are listed below:
| Characteristic |
12x12 Shock Machine1 |
36x36 Shock Machine2 |
60x60 Shock Machine3 |
- Typical shock tests range from 11 milliseconds @ 100 G’s to 35 milliseconds @ 15 G’s using long stroke gas programmer for half sine only.
- Typical shock tests range from 6 milliseconds @ 200 G’s to 13 milliseconds @ 100 G’s using four universal gas programmers.
- Typical shock tests include 11 milliseconds @ 35 G’s.
