Abstract
In this paper, the ride comfort from computer simulation was compared to the experimental result. To measure ride comforts of a passenger car, acceleration data was obtained from the floor and seat during highway running with different speeds. The measured acceleration components were multiplied by the proper weighting functions, are then summed together to calculate overall ride values. Testing several passenger cars, the ride comforts are compared. To investigate the effect of vibration signals on the steering wheel, an apparatus to measure the vibrations and weighting functions on the steering wheel are designed. The effect of the steering accelerations on the ride comfort will be investigated and added for the overall ride comfort. For the computer simulations, Korean dummy models are developed based on the Hybrid III dummy models. For the Korean dummy scaling, the national anthropometric survey of Korean people was used. To compare and check the validity of the developed Korean dummy models, dynamic responses are compared to those of Hybrid III dummy models. And the computer simulation using the MADYMO software was compared to the experimental results.
