Development of a Procedure for Multi-Axial Road Load Reproductions on an Exhaust Test Rig

OEM's increase the pressure on their suppliers to design, develop and test their products within a short time period. This requires design ‘first-time-right’ philosophy and advanced numerical and experimental methods. Four steps are required to experimentally asses the durability of exhaust systems. Environmental loads and strain references are acquired on the test track. This data is analyzed and damaging are sections retained. These sections are then reproduced on a test rig. During this reproduction, strain is measured at the reference locations and the damage is calculated and compared with the test track data.
