| 摘要 |
Vibration dummy apparatus adapted to sit on and be supported by a vehicle seat to accurately simulate human vibration response at an interface between the apparatus and seat cushions of the vehicle seat is disclosed. The apparatus includes a relatively hard and stiff skeletal frame structure having a pelvic girdle, a pair of femurs, and a pair of ball-and-socket joints for connecting their respective femurs to the pelvic girdle. Elastomeric plastic is formed over the skeletal frame structure. The elastomeric plastic has a substantially anatomically-correct, surface geometry. The elastomeric plastic formed over the pelvic girdle and the pair of femurs has mechanical properties including human-like, soft tissue spring and damping characteristics. A mass-spring system is connected to the pelvic girdle to at least partially simulate vibration response of an upper section of a human.
