Study on Bearing Dynamic Properties of Nano-particle Reinforced ZA27 Alloy Composite Material

摘要

Although the zinc-aluminum alloy has gotten substantial increase in terms of strength and friction characteristics than the traditional zinc alloy, it has limitation in the operating temperature and speed. In order to further improve the factional characteristic and expand its application range, we adopted the inexpensive zinc-aluminum alloy of ZA27 reinforced by TiC nano-particles to replace the traditional bronze alloys (ZQSn6-6-3) to produce bearing bush. And through its dynamic performance of the finite element analysis to prove particle reinforced ZA27 bearing bush has good dynamic performance.
