Simulation Research of Vehicle Exhaust System Hanger Location

Abstract

To reduce the impact of exhaust system hanger layout on the vehicle vibration performance and research the method about the reasonable layout of the hanger, forst established the FE model of an automotive exhaust system and fixed up hanger locations by modal analysis and load distribution by statics analysis. Then according to the displacement and force response to the engine’s torque loaded on powertrain’s mass centroid, adjusted hanger locations. At last, got the reasonable hanger location layout. The exhaust system hanger layout is used on a heavy truck and has the obvious effect.

Influence of the Hook Position on the Vertical Vibrations of an Automobile Exhaust System: Application of the Robust Optimization Design

“…Many researchers have carried out relevant research. Zhang et al [1] designed and adjusted the hook position of the automobile exhaust system. After the adjustment, the exhaust system was subjected to more uniform forces, avoiding the engine idle excitation frequency from the engine exhaust manifold to the exhaust tailpipe, and also reducing the dynamic reaction force transmitted to the car body.…”
