Air chamber separation and adjustable high-load air spring vibration damping device and design method

Abstract

The invention provides a high load-bearing air spring vibration damping device with air chamber separation and adjustable, comprising: a main air chamber bearing adjustment structure, composed of a main air chamber (8), a rubber film (6), an inner membrane slot structure (5 ), the upper bearing cover (4) and the height spring valve (7). The slot structure (5) is located on both sides of the film (6), the upper bearing cover (4) is located on the top of the main air chamber (8), and the height spring valve (7) is connected to the upper bearing cover (4) and the main air chamber (8); the additional air chamber group (2), including multiple sets of attached air chambers, is located between the gas source system (9) and the pipeline connection system (1); the pipeline connection system (1), the main bearing structure It adopts a separate design from the additional air chamber group (2), and is externally connected through a pipeline connection system (1). A design method of a corresponding damping device is also disclosed.

Problems solved by technology

[0002] At present, for the load-bearing of high-end precision equipment, it is generally necessary to install an air spring device and use rubber air springs to dampen the vibration. However, due to the gradual development of high-end precision equipment to a large space, and the increase in load-bearing, the installation space is limited and the air spring cannot be effectively installed. The traditional main and auxiliary integrated AS shock absorber cannot meet the needs of limited space, and the traditional method has the following defects:

The existing air spring consists of the main air chamber capsule and the auxiliary air chamber to form the spring link of the spring. The compressibility of the air realizes the elastic effect. The superposition of the main air chamber and the auxiliary air chamber increases the height of the air spring. For the installation space with limited height, Existing air springs are difficult to install and cannot be used to carry equipment

[0004] (2) It is difficult to adjust the damping multi-air chamber

The traditional air spring is composed of a main air chamber and an auxiliary air chamber. During the inflation process, the air velocity in the auxiliary air chamber is fast, resulting in high damping of the air spring.

The gas in the auxiliary air chamber is transmitted through the orifice, and the orifice needs to be manually adjusted to limit the gas flow rate, but it is difficult to adjust accurately in a short period of time. The upper load-bearing cover plate vibrates due to the difference in the gas flow rate of the main air chamber, which affects the equipment.
