panel vibration
1.Based on the routine test of rockfill, built indoor model experiment of it under the process of vibration compaction, the flat panel vibration machine was used to vibrate and compact the layered rockfill, the level instrument was used to observe the settlement of rockfill after vibration compaction, dynamical soil manometer was used to observe the pressure variety in the rockfill layer.
2.The results reveal that:(1) The subjective influencing factors includes sleep, driving time, mood, physical status and fatigue, and the objective influencing factors includes seat comfort, seat adjustability, vibration, noise, machine appearance, driving space, climate control, view, display and panel, control and control method, and fatigue.
3.The structure-acoustic coupled models of Santana 2000 are built both with and without absorption material, and ANSYS finite element analysis software is used to calculate interior acoustic pressure duc to panels vibration under specific frequency, then the acoustic contribution of panel is evaluated.
