Metal damper for alternating loads - is sintered from metal grains of different shape memory alloys and plated with sheet layers of same

摘要

The damper consists of shape memory metal. The damper is made from sintered metal grains (A-F) of different shape memory alloys spread evenly over the damper section (3) and plated across or parallel to load (8) with fullface-connected sheet layers of different shape memory alloys (A-F). Thin firmly inter-bonded metal bars of the different alloys are lined up parallel to the load direction (8) and pinned in place at uniform intervals over the damper section. The alloys (A-F) differ in their respective martensite onset temperatures (MSA-MSF), pref. by 10 to 20 deg.K. USE/ADVANTAGE - Engineering components, e.g. reversible cutter plates. Shape memory metal damper as grains, plates and bars differing in martensite onset temperature absorbs alternating loads over wide temperature range.
