摘要： PROBLEM TO BE SOLVED: To provide a fluid sound reducing device, having endurance of use in a long time and easy in maintenance by reducing fluid sound generated at an opening part.
SOLUTION: In a structure 1 provided with the opening part 1a on a surface by possessing the surface being in contact with fluid, the fluid flowing along the surface suppresses the occurrence of a vortex, when the opening part 1a is passed or the fluid sound is reduced, by relaxing the collision of vortex flow by providing a straightening body 2b or 2c composed of a porous member, on at least either the upstream side end 1b or the downstream side end 1c of the opening part 1a a flow direction of the fluid.

摘要： PROBLEM TO BE SOLVED: To provide a vibration isolating floating floor structure of a vehicle body capable of improving riding comfort and reducing in-vehicle noise.
SOLUTION: A seat floor plate 24 wherein a seat 16 is mounted is supported by a bush type vibration isolating device 26 and a hybrid type vibration isolating device 28 so as to float from a beam. In the seat floor plate 24, both side parts in a vehicular width direction (an arrow W direction) is supported by the bush type vibration isolating device 26 setting stiffness in horizontal direction to be high, and a center part in the vehicular width direction is supported by the hybrid type vibration isolating device 28 having high vertical damping force. Though vibrations from the beam intend to transfer to the seat floor plate 24, the bush type vibration isolating device and the hybrid type vibration isolating device 28 are interposed between the beam and the seat floor plate 24 to prevent the transmission of vibrations to the floor plate side, so that the seat floor plate 24 is hard to be vibrated.

摘要翻译：要解决的问题：提供一种能够改善乘坐舒适性并降低车载噪声的车体的隔振浮动地板结构。解决方案：其中安装座椅16的座椅底板24由衬套型隔振装置26和混合型隔振装置28支撑以便从梁上浮起。在座椅底板24中，车宽方向（箭头W方向）的两侧部分被套筒式防振装置26在水平方向上的设定刚度支撑得较高，车宽方向的中心部分由具有高垂直阻尼力的混合型隔振装置28支撑。虽然来自梁的振动意图转移到座椅底板24，但是衬套型隔振装置和混合型防振装置28夹在梁和座椅底板24之间，以防止振动传递到地板使得座椅底板24难以振动。版权所有（C）2007，JPO＆INPIT
