Abstract

To evaluate human comfort effectively during automobile driving

the driving comfort simulation and evaluation are carried out under vibration. A biomechanics model of human body and seat is established based on Adams/LifeMode

and the power spectral density functions for grade B and C roads are gained and transformed into the time-domain signals that gets loaded easily. The acceleration of vibration response of the key parts of a human body is computed at typical running speeds.The simulation evaluation method of whole body vibration comfort as well as the calculation method of partial human body vibration comfort is proposed. It is an instructive attempt to realize the biomechanics modeling of human body and seat and human body comfort evaluation based on Adams/LifeMode

to differ from traditional spring-damping-mass model system.
