AI Technical Summary

Technical Problem

Existing aluminum alloy damping spacers exhibit decreased mechanical properties under extreme environments and suffer from defects such as porosity, cracks, and inclusions, failing to meet the requirements of extreme working conditions such as repeated icing and strong corrosion.

Method used

High-strength titanium alloy material is used, combined with a single frame structure and fixed connection shaft design. Nb, Mo, Cu, Zr, Si and B elements are added. Hydrogenated styrene-butadiene block copolymer/acrylate rubber is used to prepare buffer and damping pads, and damping spacers are prepared by vacuum plasma welding and die forging processes.

Benefits of technology

It improves the structural strength and corrosion resistance of the damping spacer, extends its service life, is suitable for extreme environments, has a tensile strength of 950MPa and an elongation of ≥14%, and maintains high reliability under extreme working conditions.

Abstract

The invention discloses a damping spacer and a preparation method thereof, and relates to the technical field of alloys. The damping spacer comprises a frame, a wire clamp and two fixedly-connected rotating shafts, the frame is connected with the wire clamp through the fixedly-connected rotating shafts, and the two fixedly-connected rotating shafts are located on the two sides of the frame respectively and are symmetrically arranged; the wire clamp comprises a wire clamp cover plate, a wire clamp main body and a rotating shaft; the wire clamp cover plate and the wire clamp main body are connected through the rotating shaft; the damping spacer further comprises a limiting shaft used for limiting the wire clamp body to rotate around the fixed connecting shaft and a nut used for fixing the wire clamp body, the frame and the fixed connecting shaft. A locking pin is arranged on the wire clamp main body, and the end part of the locking pin is connected with a cotter pin; the damping spacer is made of titanium alloy. The damping spacer has the advantages of being high in strength and corrosion resistance, and can solve the problems that an existing line fitting is insufficient in reliability and short in service life under the extreme environment working condition.
