Battery Mechanical Shock Test System Half-Sine Sawtooth Square Wave Shock Tests

Product Information:

This mechanical shock tester is mainly suitable for shock resistance tests in the fields of electronic products, aerospace, shipbuilding, defense sectors, automotive parts, transportation, etc.

By selecting different waveform generators, half-sine wave, post-peak sawtooth wave or square wave Shock tests can be performed.

The system meets industry testing standards such as GB/T2423-2008, GJB150, IEC-68-2-27, and U.S. industrial reliability standards like MIL-STD-202F, MIL-STD-810F, and MIL-STD-883E. (Note: MIL standards refer to widely adopted reliability protocols.

Main Performance:

1. This equipment adopts hydraulic lifting and high-pressure oil brake free-fall shock machine.

2. This equipment adopts gas-liquid pressurization and strong friction brake to prevent secondary shock braking.

3. Shock measuring instrument: single-channel data acquisition. It can simultaneously perform acceleration data measurement, storage, report printing, data callback, database management and other functions of two channels.

4. This equipment adopts rubber module to generate a wide range of half-sine wave pulses of any action time.

5. This equipment can be used for equivalent drop test of packaging boxes.

Technical Parameter:

Equipment performance introduction:

1. Working platform

Adopt high-strength imported aluminum alloy working platform.

2. Lifting mechanism

Adopt hydraulic lifting system.

3. Lifting height control

The lifting height is measured by the photoelectric encoder assembly installed on the base. Photoelectric encoder measurement has the advantages of high precision, strong anti-interference ability and high reliability. It ensures the repeatability of shock.

4. Braking system

Adopts pneumatic braking. The strong friction brake and anti-secondary shock braking function can brake quickly and reliably. Prevent secondary rebound.

5. Buffer system

It consists of a base, a damper, and an airbag. The vibration reduction system can reduce the shock force transmitted from the working platform to the ground.

6. Waveform generator

Half-sine wave: realize different impulse pulse widths 1-30ms;

Square wave: composed of special cylinder and pressure regulating valve;

Post-peak sawtooth wave: composed of special mold, furnace and lead block.

7. Safety device

Emergency stop switch: It cuts off the circuit in emergency situations such as forced disconnection of the contact welding of the action mechanism.

Measurement System Features:

Complies with MIL-STD-810, GJB-150-18-86, IEC68-2-27

Maximum sampling frequency up to 1MHz

Maximum test acceleration 100,000gn

Minimum test pulse width 0.1ms

Multi-frame waveform recording and playback

Support internal and external triggering

Analysis Functions:

1. Shock waveform transient capture

Transient capture helps you get single or multiple pulses. The system automatically analyzes the peak value, pulse width, velocity change, head injury index HIC and other data of the shock pulse. Automatically match the captured pulse waveform to the ideal waveform and compare the deviation between the two.

2. Shock response spectrum analysis

Shock response spectrum analysis can evaluate the potential damage caused by the impact. Provide a basis for designing the impact resistance of products. The system performs SRS analysis on each shock pulse and compares the deviation between the actual SRS and the target SRS.

3. Other analyses

Force deformation analysis, shock response demonstration, rotation shock analysis and other necessary analyses in shock tests. Force deformation analysis calculates the force peak, deformation peak, energy, efficiency, etc. generated by the pulse. Shock response demonstration provides tools for learning shock response spectrum. Rotation shock analysis is used for rotary shock machines or other rotary control events. The signal is calculated by axial acceleration measurement.
