Office chair rotating life testing machine

Office chair rotating life testing machine

one. Test scope:

The testing machine simulates the rotation condition of the user sitting in the chair during actual use. Make the chair wheel under a certain load, under the condition of continuous rotation or reciprocating rotation at a certain Angle, after a certain number of times, check its damage. The purpose is to evaluate the ability of the chair wheel to withstand fatigue strength and wear.
