2. Strong ability to adapt to the environment: the instrument is flexible and convenient to move, which is convenient for experiments in various environments.

3. High precision and good data repeatability: use well-known brａnd high-precision pressure sensors to ensure the accuracy and stability of test force values.

4. High-speed data acquisition system: Adopt ARM9-based high-speed data acquisition system structure, adopt system clock circuit design, hard double buffer to realize continuous acquisition and storage, and increase system anti-interference design to solve the problem of signal acquisition.

5. High test efficiency: 60S to complete the number of tests shock absorption test (4 times) vertical deformation test (3 times).

6. Control interaction interface: use professional computer operation or use professional industrial touch screen computer (its configuration and stability are much higher than the touch screen terminal in the general sense, and there is no need to connect any other terminals such as PCs and laptops to complete the operation. all work).

7. Fast processing speed: AD acquisition method is adopted, with a maximum rate of 500KHz, and the processing capacity and use speed are improved across levels.
