  • Method and system for dynamic testing of a vehicle exhaust system in a rigid frame test fixture
    Patent number: 6304829
    Abstract: A method and system are provided for generating engine attachment control boundary conditions and corresponding control signals for an exhaust system laboratory test fixture which accurately reproduce both the dynamic behavior of a vehicle powertrain during operation, and the dynamic behavior of the vehicle frame during operation in the area where the exhaust system is attached to the vehicle frame. Road load data is collected in vertical, lateral, and longitudinal directions on the vehicle frame during vehicle operation at each of the locations where the exhaust system attaches. In addition, temperature and thermal cycling data are also collected during operation of the vehicle. The road load data is used to determine a best fit rigid body model. Accelerometer locations and directions are determined from statistical analysis and ranking to find the measures best fitting the determined rigid body.
