Helmet wind tunnel testing machine

HT-6050Helmet wind tunnel testing machine

Purpose:

Helmet wind tunnel testing machineUsed to simulate the impact of different wind speeds and directions on the user of a helmet in a usage environment, in order to evaluate its wind resistance performance.

Equipment Technical Specifications:

1. Wind outlet area: 1m²Meet the full-size testing requirements for adult/child helmets and helmets with accessories;

2. Wind speed: ≥ 20m/s, expandable to 40m/s;

When the wind is uniform, the local airflow deviation angle within 80% of the cross-sectional area at the center of the test section shall not exceed 1 °;

4. The turbulence intensity in the central area of the experimental section shall not exceed 3%;

5. Wind speed stepless speed regulation, real-time display of wind speed in the wind field;

6. It can simulate special wind field environments such as uniform wind, time-varying wind, shear wind, gusts, and vertical wind fields

7. The test head mold support frame can meet the requirements that the left and right angles of the head mold can cover ± 90 ° and be adjusted, and the up and down tilt angles can cover ± 45 ° and be adjusted, with an angle measurement error of ≤± 0.5 °;

8. Can test helmet wind resistance with an accuracy of not less than 1%;

9. Support visual smoke flow imaging, smoke generator spraying distance ≥ 3m, can be remotely controlled;

10. The head has a heating function inside, and the heating temperature range can cover (35 ± 10) ℃ with an accuracy of ≤ 0.1 ℃. It can test the internal temperature of the helmet and the wind noise inside and outside the helmet with an accuracy of ≤ ± 1dB;

11. Support generating graphical and other forms of reports from test data, and can achieve data transmission and other functions through network connection to wind tunnels;

12. The equipment supplier is responsible for the renovation of power supply, pipelines, and site;

13. Can be extended to electric bicycle testing;

14. Convenient for relocation and easy to move between multiple testing sites;

15. It can be expanded to simulate complex environments such as rain, snowfall, haze, and sandstorms;

16. The sample testing section can be expanded to accommodate test samples with dimensions of 2000mm × 800mm × 1500mm
