Area of Science:
- Mechanical Engineering
- Materials Science
- Testing and Measurement
Background:
- Existing drop table machines have limitations for high-g shock environment simulation.
- There is a need for simpler, more accessible shock testing equipment.
Purpose of the Study:
- To develop and validate a novel, simply constructed shock tester for high-g level shock environment simulation.
- To demonstrate the capability of the device to achieve acceleration levels exceeding 60,000 g.
Main Methods:
- A theoretical model and structural design of a new drop tester were established.
- A prototype device was constructed using carbon fiber reinforced polymer.
- Experiments were conducted using a Brüel & Kjær high-g accelerometer to validate the design.
Main Results:
- The developed shock tester successfully simulated high-g shock environments.
- Acceleration levels in excess of 60,000 g were achieved.
- The device's performance was verified through experimental testing.
Conclusions:
- The simply constructed shock tester is a viable alternative for high-g shock simulation.
