Vibration reduction rubber pad capable of effectively reducing vibration

Abstract

The invention discloses a vibration reduction rubber pad capable of effectively reducing vibration, the vibration reduction rubber pad comprises an upper rubber layer and a lower rubber layer, the top of the lower rubber layer is provided with a plurality of fixing columns, the fixing columns are arranged to be of an oval table structure, the fixing columns are evenly distributed on the top of the lower rubber layer, the fixing columns are sleeved with springs, and the springs are arranged on the fixing columns. The spring is arranged to be a rubber spring or a metal common spring, the upper rubber layer is installed on the fixing column through a fixing bolt, a threaded hole is formed in the fixing column, and a through hole is formed in the top of the upper rubber layer. According to the train rail rubber pad, the springs are arranged outside the fixing columns and distributed at equal intervals, the overall elasticity of the train rail rubber pad is improved by means of the characteristics that the elasticity modulus of the springs is small, the springs have large elastic deformation after being loaded, and impact and vibration can be effectively absorbed, and meanwhile the overall elasticity of the train rail rubber pad is improved by means of the principle that the rigidity is increased after the springs are connected in parallel. The overall rigidity of the rubber anti-vibration pad is improved, and the overall bearing capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation and vibration reduction, and in particular relates to a vibration-damping rubber pad for effectively reducing vibration. Background technique [0002] With the continuous improvement of the level of urbanization in our country, the vibration generated by various vibration sources has become one of the important problems that plague people's daily life and work. Various vibration sources such as roads, railways, construction, and power machines will produce environmental vibrations that cannot be ignored. Some high-tech laboratories have impacts that cannot be ignored, and even endanger the service life. On the other hand, with the development of science and technology, more and more high-precision instruments are put into use, followed by increasing requirements for anti-micro-vibration, the vibration amplitude requirements have reached the nanometer level, and the vibration speed req...

Problems solved by technology

[0003] In recent years, elastic backing plates are usually used between the rails and sleepers in the track structure of rail transit to absorb vibration energy and play a role in reducing noise and vibration. The requirements for vibration control of objects are getting higher and higher, and the existing elastic pads are difficult to meet the requirements. Although the vibration-damping rubber pads have been put into use, due to the uncontrollable stiffness and lack of sufficient elasticity and stiffness, in actual engineering applications There are still many problems, causing inconvenience
