Customized domestic drop hammer impact testing machine

Instrumented oscilloscope drop hammer impact testing machine

ZKCLC-AI

Instrument Overview:

Instrumented oscilloscope drop hammer impact testing machine-This testing machine mainly tests the impact resistance of materials, that is, by freely dropping a certain mass of hammer at a certain height to impact the sample, and synchronously collecting data on the impact contact of the hammer on the sample at a high rate, analyzing the impact resistance of the sample and the damage and fracture status of the sample.

The composite material drop hammer impact testing machine produced by our company adopts new sensor measurement and control technology, which can real-time collect the velocity variation curve of the drop hammer impact plate process. The instantaneous maximum impact velocity and maximum rebound velocity are used to calculate the impact kinetic energy and the energy absorbed when the material is damaged. Through software data analysis, the impact load and impact point displacement variation curves over time are obtained.

This composite material drop hammer impact testing machine can perform data analysis through software: maximum impact force, maximum impact energy, maximum impact velocity, material absorption energy and damage dissipation energy, damage critical point and ductile brittle transition point

Explanation of Instrument Advantages

1. Horizontal calibration: The host can be adjusted horizontally to ensure the verticality of the hammer

2. Data validity: Equipped with both impact force sensors and acceleration sensors, the dynamic display of dual trend impact graphs facilitates effective comparison of test data and facilitates judgment of its validity

3. 3D graphics: capable of simulating and displaying impact points in a three-dimensional trapezoidal shape, more vivid and intuitive

4. Impact deformation: It can simulate the impact deformation of the hammer head during the process of impacting the specimen, replay the image, and calculate the numerical value of the deformation

5. Impact speed: Crown Test independently developed a collection impact speed grating with a response time of 0.5 μ s (the response time of existing products in the market cannot meet the testing requirements)

6. Data collection: The data collection card directly collects the MV voltage signal of the sensor, with faster collection speed and higher accuracy (if collected after an amplifier, there will be delay and signal distortion)

7. Core components: High speed data acquisition card, NI from the United States, ensuring data stability and reliability

8. Impact mode: can be selected from three modes: impact energy, impact height, and impact velocity
