Kawasaki has developed a methodology for estimating car body low mode bending and torsion mode natural frequency. These natural frequencies have a significant influence on ride quality. Although it has been believed that the natural frequencies become lower when passengers are present, Kawasaki established that the natural frequency does not change with the number of standing and sitting passengers, and the vibration acceleration amplitude becomes smaller when passengers are present. This has been shown by implementing numerical analyses and experiments using a mock up car. The increased knowledge will enable designing for better ride quality in the future through optimization of more accurate models.
