2、 Instrument Overview:

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

Energy storage elastic device

Storage elastic part: provides a certain initial velocity for the hammer head to increase the velocity at the moment of contact between the hammer head and the impact material, thereby achieving a certain energy of impact force. The device is driven by a servo motor to drive a ball screw, and the increase in impact energy is determined by the pressure applied to the hammer head by the device.
