Description:

Office Chair Seat Back durability tester is used for testing the strength and durability of office chair. Made of Aluminum material frame, PLC contral, easy operation; high precision force sensor for the load application.

Seat and chair back durability combined tester.

Working Principle:

Staic tests: tests consisting of havy loads being applied a few times to ensure that furniture has sufficient strength under the highest levels of loading that might reasonably be expected to occur.

Fatigue test:Test simulating the repeated application of loads or movement of components occurring during long-term functional use.

This test appratus do the durability test to chair seat and backrest by simulating the loading application to the chair as daily use.First use the seat loading pad to apply the certain loading to the seat surface, then the back loading pad to the backrest, then loading unload to finish one cycle of test, repeat the loading movment some times and certian cycles according to different test requirement, to determin the durability permance of chairs.

Loading 600N on the seat surface,and then load 192N on the chair back

Repeated motion 200000 times in frequency of no more than 40times/min.
