System Principle:
The impact test table is compact and meticulously designed through finite element analysis. It boasts high structural strength and a high frequency response. High-acceleration impact tests have demonstrated an acceleration duration of 0.5ms, with a semi-sine impact waveform that meets test specifications. It also features a built-in secondary impact protection device and a high-efficiency vibration damping mechanism. The impact height can be digitally set and automatically executed.
Working Principle:
The test piece is mounted on a workbench, which is guided up and down by two high-precision sliding rails. Two pneumatic cylinders are connected to the workbench via the sliding rails. When the cylinders are inflated, the piston rods rise, driving the workbench upward. The workbench then rises. When it reaches the set height, the cylinders rapidly deflate, causing the bottom of the workbench to impact the waveform generator, completing the impact process. Adjusting the workbench's height allows for different initial velocities and, consequently, different impact overload values. Changing the waveform generator's stiffness allows for different pulse widths. These two factors work together to produce a variety of test waveforms that meet design specifications.
Product Features:
1. Single-machine control and measurement management, with a remote control interface for convenient operation. The system stores various waveform differential bands for easy adjustment and application, and automatically generates test reports upon completion.
2. A laser displacement sensor is used for height measurement. Once the height is set, the computer automatically controls the height, providing high accuracy and repeatability.
3. A built-in pneumatic brake mechanism ensures safety and reliability.
4. The device features built-in high-performance vibration damping and isolation, eliminating the need for a dedicated foundation and facilitating installation.
