Experimental Verification of Correlation between Objective and Subjective Evaluation of Passenger Car Vibration Comfort

The paper deals with the experimental investigation of the correlation between objective and subjective evaluation of vibration comfort in passenger cars. The ride comfort plays an important role in the vehicle design as well as in vehicle judgment. Current standard approaches towards vibration comfort evaluation more or less focus on one-dimensional vibration evaluation of human body response. This paper describes the results of experimental verification of a new approach for vibration comfort in passenger cars. This new approach measures the influence of multiple vibration modes of a vehicle on the integral subjective human vibration perception. The experiments have verified that the correlation between the objective and subjective vibration comfort evaluation is almost 1:1. Moreover this paper describes the repeated experiments that prove the concept in larger scale.
