Structural Strength Analysis at Cushion Frame and Back Frame of Automotive Seat

Analysis of Friction Noise and Vibration from the Cushion Frame of a Driver’s Seat in Passenger Cars

In this study, the vibration and noise for the cushion frame that directly contacts the driver of the car are investigated. The friction noise from the seat track generating the largest noise is measured and analyzed. Also, vibration measurement and analysis are performed in parallel to locate the position from where the noise is generated. In the next stage, the RPM of motor and the current ch...

Automotive Ride-Comfort Improvement with an Air Cushion Seat

In this paper, for the purpose of improving the ride comfort of a passenger car, the use of an air-cell on top of the conventional polyurethane foam seat is proposed. The air-cell can be modeled as a variable spring with the change of its internal air pressure. Therefore, for different human sizes and road disturbances, the adjustment of the air-cell can make the optimal contact pressure betwee...

Vibration characteristics of tractor seat cushion materials

Operators of agricultural machinery are exposed to an extensive range of indirect vibrations through the seats, which gradually causes chronic damages. One of the ways to reduce the vibrations imposed on the operators is to use appropriate materials in tractor seat cushion. The present study was carried out in order to select appropriate foam or sponge and investigate different factors in reduc...
