Helmet Strap Tensile Tester
The helmet strap tensile testing machine is designed to simulate tensile, impact, and durability loads encountered in actual use, accurately evaluating the mechanical properties of the straps and their connecting components. It has wide applications for quality inspection agencies, manufacturing companies, and researchers. The equipment's design is based on material mechanics testing principles and utilizes a precision servo control system to perform various dynamic and static tests.
Application
Apply a certain initial load to the helmet strap system for a certain period of time. Then, let a weight of a certain mass fall from a certain height so that the impact force is also applied to the strap system, thereby evaluating the tensile performance of the strap system.
Standard
GB 24429-2009:Sports helmets - Safety requirements and testing methods for sports helmets for cyclists and users of skateboards and roller skates
Feature
High-precision strain gauge force sensor: Measurement accuracy up to ±0.5% FS, resolution 0.1N, ensuring the accuracy of test results.
High-precision optical encoder: Real-time monitoring of displacement changes, minimum resolution 0.01mm, providing accurate displacement data.
Multiple test modes: Including constant-rate tensile testing, load-holding testing, and cyclic fatigue testing, meeting the testing requirements of different standards.
Safety protection devices: Emergency stop button, overload protection system, and splash guard ensure operator safety.
International mainstream safety standards: Strict requirements on helmet strap performance ensure that the product meets safety standards.
