摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which can enhance a soundproof effect by reducing not only vibrations of the rail but also noises from the rail.
SOLUTION: The covering member 8 is detachably attached to the top surface and undersurface of a bottom section R
2 of the rail, and detachably attached to both side surfaces of a belly section R
3 of the rail. In the covering member 8, a sound absorbing layer 9a for absorbing the noises from the rail R is provided inside, and a vibration control layer 10a for suppressing the vibrations generated on the rail R is provided outside. When the layer 9a is formed of a viscoelastic body, it constitutes a flexible spring and an attenuator (dash pot), makes the vibrations from the rail R hardly propagate from the layer 9a to the layer 10a, and converts a part of vibrational energy of the rail R into thermal energy by making viscosity bring about vibration damping, so as to absorb and damp the vibrations. Consequently, the noises, which are emitted outward from the layer 10a, are reduced.

摘要： PROBLEM TO BE SOLVED: To provide a soundproof structure of a rail, which enables a covering material to be firmly fixed to the rail, which facilitates manufacturing and construction, and which can enhance a soundproof effect.
SOLUTION: A right-side covering member 8a is mounted on the right-side lateral surface of the rail R, and a left-side covering member 8b is mounted on the left-side lateral surface of the rail R. After that, a right-side holding member 11a is mounted on the member 8a at a predetermined interval in the longitudinal direction of the rail R, and a left-side holding member 11b is mounted on the member 8b. Subsequently, a bolt 11h is inserted into through-holes 11f and 11g, and a nut 11i is attached to the bolt 11h, so that the members 11a and 11b can be connected together. Thus, even if increasing in thickness and weight, the covering member 8 can be firmly fixed to the rail R by means of a fixing member 11. Consequently, since vibrations generated on the rail R are reduced and acoustic radiation from the rail R is suppressed, a soundproof and vibration-control effect can be enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a sound insulation structure of a rail, reducing noise generated from a joint part of a rail by sound insulation material of a simple structure.
SOLUTION: Sound insulation materials 10A, 10B are removably fixed to rails 6A, 6B in front and in the rear of the joint part by a fixing member 11 at a space from the side of the joint part between the rails 6A, 6B to reduce noise generated in the joint part between the rails 6A, 6B. The sound insulation materials 10A, 10B are disposed at a space between both side surfaces of the joint part between the rails 6A, 6B and the inside surfaces of the sound insulation materials 10A, 10B, and provided with a sound absorbing material 10a on the inside and a vibration control material 10b on the outside. When a wheel passes on the rails 6A, 6B in front and in the rear of the joint part to vibrate the rails 6A, 6B, the sound absorbing material 10a prevents rolling noise from the rails 6A, 6B from being transmitted to the vibration control material 10b, so that vibration of the vibration control material 10b is reduced and radiating sound from the vibration control material 10b is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a noise reduction structure of a viaduct capable of reducing the noise of structures from the viaduct.
SOLUTION: This noise reduction structure damps the vibration energy of a floor slab E
1 since a vibration damping layer 2 suppresses a floor slab lower surface E
3 because the upper surface of the damping layer 2 is fitted to the floor slab lower surface E
3 . Though the soft elastic material of the damping layer 2 shearingly deforms due to the vibration of the floor slab E
1 , the vibration of the floor slab lower surface E3 is damped by covering a part of the vibration energy into a heat energy by an internal loss due to the viscous resistance of a soft viscoelastic material. Further, since a constraint layer 3 is stacked on the damping layer 2, the deformation of the damping layer 2 is retrained by the restraint layer 3. Since the shearing deformation of the damping layer 2 is amplified and the internal loss of the damping layer 2 is amplified, the vibration damping capability of the damping layer 2 can be largely increased. By stacking damping layers 2 and the restraint layers 3 with low rigidness are stacked, spring-dash pot-mass structure is formed as an physical system, and the vibration is also cut off.

摘要翻译：要解决的问题：提供能够降低高架桥结构噪声的高架桥的降噪结构。解决方案：由于振动阻尼层2抑制了地板坯下表面E 3 ，因此，该降噪结构减小了地板E 1 的振动能量，因为上部阻尼层2的表面装配到地板下表面E 3 。尽管阻尼层2的软弹性材料由于地板E的振动而剪切地变形，但是通过将一部分振动能量覆盖在底板下表面E3的振动中来阻尼，由于软粘弹性材料的粘性阻力而引起内部损失的热能。此外，由于约束层3堆叠在阻尼层2上，阻尼层2的变形被约束层3再次拉伸。由于阻尼层2的剪切变形被放大，阻尼层2的内部损耗被衰减，阻尼层2的减震能力可大大增加。通过层叠阻尼层2和低刚性的约束层3，形成弹簧箱体结构作为物理系统，并且振动也被切断。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flexible piezoelectric material capable of improving piezoelectric effect with a simple structure, to provide a method of manufacturing the piezoelectric material, to provide a damping device, and to provide a drive unit. SOLUTION: The piezoelectric material 1 is a member, where a plurality of piezoelectric particles 2 are dispersed into a medium 3. The piezoelectric material 1 is manufactured by, for example, dispersing the piezoelectric particle 2, such as lead zirconate titanate, into the medium 3 with flowability, such as uncured silicone rubber, before the medium 3 is heated and cured by applying a voltage V to the medium 3. As a result, the piezoelectric particles 2 are oriented continuously in the direction of an electric field E so that the direction of the electric field E applied to the medium 3 becomes the same as the polarization direction of the plurality of piezoelectric particles 2. Therefore, polarizability in the orientation direction of the piezoelectric particles 2 becomes higher than that in conventional piezoelectric rubber, the large electric field E is generated when mechanical stress is applied and large strain is generated when the electric field E is applied, and hence large piezoelectric effect can be obtained.
