Seat System Fatigue Test 950146

Currently one OEM requires seat system to pass a fatigue test consisting of a varying load applied to the seat back for a large number of cycles. The test was derived from a seat occupant study documented in SAE paper 840509, Passenger Car Seating Loads; A Human Factors Engineering Problem. This test takes an average of two weeks to complete for a given program. The purpose of our study is to develop an equivalent fatigue test that shortens the required test time and provides the same results and confidence.
