Computer-controlled Helmet Impact Tester
A computer-controlled helmet impact tester is an instrument used to test the impact resistance and penetration resistance of helmets. It quantitatively measures the impact resistance and energy absorption capacity of helmets by simulating the impact of objects falling from a height. The core principle of the testing instrument is the law of conservation of energy and the momentum theorem. During testing, the impact hammer is raised to a specified height, released, and allowed to fall freely, converting potential energy into kinetic energy to deliver a sudden impact to the helmet sample.
Application
This testing instrument is applicable to the impact - energy absorption performance test of helmets. It is used to evaluate the impact - resistance performance and penetration - resistance of helmets.

Feature
High Precision: Utilizes a servo motor and hollow gear reduction system to ensure high accuracy and reliability of testing.
Automation: Automatically lifts the fixture to a predetermined height, displaying height, peak acceleration, test curve, impact velocity, impact time, and impact energy in real time.
Multifunctional: Employs a direct-drive transmission system with high positioning accuracy, long lifespan, low friction, and capable of high-speed and bidirectional rotation.
Safe and Fast: Features a position limiting function, making tests with position limitations safer and faster.
Wide Application Range: Offers a very wide measurement range, suitable for standards in multiple countries.
Integrated Design: Adopts an integrated design principle; regardless of the host configuration, only the corresponding parameters on the computer need to be modified (parameters can be saved), eliminating the need for circuit adjustments.
