具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
如图1所示，本发明实施例一种变频隔振器，适用于船舶设备减振降噪工程，它包括上部安装面板结构1、中部金属板2、下部安装面板结构3、内部橡胶圆柱体4、上部橡胶环柱体5及下部橡胶环柱体6。上部橡胶环柱体5套在所述内部橡胶圆柱体4的上部，其内侧与内部橡胶圆柱体5的外侧粘接联接；上部安装面板结构1与内部橡胶圆柱体4和上部橡胶环柱体5的顶部硫化联接；下部橡胶环柱体6和中部金属板2套在所述内部橡胶圆柱体4的下部，且均与内部橡胶圆柱体4之间留有间隙；外部橡胶环柱体6的顶部与中部金属板2的下表面硫化联接；下部安装面板结构3与内部橡胶圆柱体4和下部橡胶环柱体6的底部硫化联接；内部橡胶圆柱体4、中部橡胶环柱体5、外部橡胶环柱体6的刚度逐级递增。As shown in Figure 1, the embodiment of the present invention is a frequency conversion vibration isolator, which is suitable for ship equipment vibration and noise reduction projects, and it includes an upper installation panel structure 1, a middle metal plate 2, a lower installation panel structure 3, and an inner rubber cylinder 4. The upper rubber ring cylinder 5 and the lower rubber ring cylinder 6. The upper rubber ring cylinder 5 is set on the upper part of the inner rubber cylinder 4, and its inner side is bonded to the outer side of the inner rubber cylinder 5; the upper installation panel structure 1 is connected with the inner rubber cylinder 4 and the upper rubber ring cylinder 5 The top of the vulcanized connection; the lower rubber ring cylinder 6 and the middle metal plate 2 are set on the lower part of the inner rubber cylinder 4, and there is a gap between them and the inner rubber cylinder 4; the top of the outer rubber ring cylinder 6 vulcanized connection with the lower surface of the middle metal plate 2; vulcanized connection between the lower installation panel structure 3 and the bottom of the inner rubber cylinder 4 and the lower rubber ring cylinder 6; the inner rubber cylinder 4, the middle rubber ring cylinder 5, and the outer rubber ring The rigidity of the cylinder 6 increases step by step.
本发明实施例变频隔振器在工作时，上部安装面板结构与设备联接，在重力作用下，首先是内部橡胶圆柱体压缩，当压缩量超过中部橡胶环柱体下部与中部金属板上部之间的距离时，中部橡胶环柱体及外部橡胶环柱体受压缩，系统刚度变大，频率发生变化，从而使减振器的阻尼增大，对设备振动的缓冲能力也加大。When the frequency conversion vibration isolator of the embodiment of the present invention is working, the upper installation panel structure is connected with the equipment. Under the action of gravity, the inner rubber cylinder is compressed first. When the compression exceeds the middle rubber ring cylinder lower part and the middle metal plate upper part When the distance is greater, the central rubber ring cylinder and the outer rubber ring cylinder are compressed, the system stiffness increases, and the frequency changes, thereby increasing the damping of the shock absorber and increasing the buffering capacity of the equipment vibration.
