Hydraulic Vertical Shock Test System with Half-Sine Waveform
Generator
Product Information:
This machine is mainly suitable for shock tests in the fields of
electronic products, aerospace, ships, military industry,
automotive parts, transportation, etc. By selecting different
waveform generators, shock tests such as half-sine wave, post-peak
sawtooth wave or square wave can be performed.
The equipment meets the test specifications of MIL-STD-202F,
IEC-68-2-27, MIL-STD-810F, MIL-STD-883E, etc.
Environmental requirements:
1. On-site temperature: 5℃~+28℃ (average temperature within 24
hours ≤28℃);
2. Relative humidity: ≤85%RH;
3. Air source: 0.5--0.8MPa
4. Power supply conditions: three-phase five-wire;
5. Voltage range: AC380V;
6. Allowable frequency fluctuation range: (50±0.5)Hz;
7. The grounding resistance of the protective ground wire is less
than 4Ω;
8. The user is required to configure an air or power switch of
corresponding capacity for the equipment at the installation site,
and this switch must be used independently for this equipment.

Shock machine main introduction:
1. Working platform: high-strength imported aluminum alloy working
platform is adopted.
2. Lifting mechanism: hydraulic cylinder lifting and lowering.
3. Lifting height control: the lifting height is measured by the
photoelectric encoder assembly installed on the base. The
photoelectric encoder measurement has high precision, strong
anti-interference ability, high reliability, and ensures the
repeatability of the shock.
4. Braking system: pneumatic braking strong friction brake
anti-secondary shock braking function is adopted to prevent
secondary rebound
5. Buffer system: effectively reduce the shock force of the shock
test on the ground, and a self-buffering system is designed, which
consists of a base, a damper, and an airbag.
