A flexible fitting

Abstract

The invention relates to a flexible adaption device and belongs to the field of mechanical vibrating isolation. The flexible adaption device is composed of a grooved circular pipe, an upper mounting connection structure and a lower mounting connection structure, wherein the upper mounting connection structure and the lower mounting connection structure are connected to the two ends of the groovedcircular pipe. The upper mounting connection structure and the lower mounting connection structure are flange plates. Annular wave beams and a plurality of short beams perpendicular to the annular wave beams are formed in the pipe wall of the grooved circular pipe in a grooved mode in the axial direction and the circumferential direction of the grooved circular pipe. By controlling the size of thegrooved circular pipe, the heights of the annular wave beams and the distribution mode and the heights of the connecting beams, the requirements for rigidity and structural strength in each directionof the flexible adaption device are met. The flexible adaption device has the multiple advantages that axial and radial rigidity distribution is flexible, the bearing range is large, the structure iscompact, the space utilization rate is high, connection of the device with other external parts is facilitated, and batch production is convenient and other advantages.

Description

technical field [0001] The invention belongs to the field of mechanical vibration isolation, and in particular relates to a flexible adaptation device that can meet the rigidity requirements in all directions. Background technique [0002] Vibration isolators and dynamic vibration absorbers are widely used in vibration isolation design problems in the fields of machinery and construction engineering. In recent years, in the field of aerospace, especially in the design of earth observation and astronomical observation satellites, due to the higher and higher design resolution, the excitation sources such as flywheels and refrigerators in the satellite platform, or the vibration of remote sensing cameras, etc. For sensitive equipment, vibration isolation measures are generally taken. The design of typical vibration isolators and dynamic vibration absorbers must include components that provide stiffness, and the performance of components directly affects the vibration isolatio...

AI Technical Summary

Problems solved by technology

In some occasions that require a high shaft-to-radial stiffness ratio, this slotting method requires additional external space (increased height) or reduced internal available space (reduced diameter)

In addition, since the force is realized in the form of bending of a single-end fixed beam, when the design stiffness of the adapter device decreases, the static load-bearing capacity in the corresponding direction also decreases, so when the adapter device is applied to low-frequency vibration isolation When there is a problem, the design must consider adding an additional locking and unlocking device or a limit device
