Application
The instrument is suitable for helmet impact energy absorption performance testing and is used to evaluate the impact resistance performance of helmets.
The equipment adopts a HOTOTECH independently developed upper-computer control system, which automatically lifts the fixture to the preset height and displays the height in real time. The operating interface also provides real-time display of the acceleration peak value, test curves, impact velocity, duration, impact energy, and other relevant parameters.

Features
1.Main Equipment Functions and Features
The impact height can be freely set and is displayed in real time; once the preset height is reached, the lifting mechanism stops automatically.
The base features high impact resistance, securely mounts all related components, and is provided with reserved mounting holes.
The headform and helmet clamping, engagement, and release are controlled electrically.
Dedicated test fixtures are used, allowing convenient replacement between full headforms and half headforms, enabling testing of full-face or half helmets.
The full-helmet test system is specially designed to allow 360° rotation of the helmet, enabling five impact locations to be tested: top (crown), rear (occipital), front (forehead), and both sides (ear areas).
Both the lifting and release mechanisms of the headform adopt a dual guide-rail structure to ensure smooth and stable vertical drop.
The flat anvil and hemispherical anvil use a plug-in mounting design, allowing quick installation and replacement.
Speed measurement and motion control are managed by a mechanical–electrical PLC control system, while data are collected by a computer. The system displays the acceleration peak value in real time, plots acceleration curves, and allows test reports to be stored and printed, with test time and curves clearly shown.
The impact area is equipped with a 180° rotatable high-strength protective shield.
The software includes a dedicated calibration module, allowing calibration and adjustment of the acceleration sensor, displacement, communication frequency, sampling frequency, and other parameters.
The software supports lifetime free upgrades and must be an independently developed, multifunctional helmet testing equipment operation and control system.
2.Hardware Features
The overall structure is constructed from thickened square tubing, channel steel, and solid steel, providing excellent stability.
The machine surface is finished with a baked paint coating process, offering strong corrosion resistance and an attractive appearance.
The test support frame is detachable, facilitating installation and setup.
3.Software Features
Controlled by a touchscreen PLC program, ensuring convenient and user-friendly operation.
Equipped with travel limit protection and leakage (earth fault) protection to ensure operational safety.
Includes abnormal fault alarm prompts to further enhance operational safety.
