Abstract:

Based on the comprehensive analysis of common types of HVC ( High-Velocity Compaction) equipment,a mechanical energy storage-type HVC method is put forward,and the corresponding test machine is designed.Then,the operating principle of the machine is briefly introduced and the mathematical models of velocity and kinetic energy of the hammer are deduced. Moreover,the virtual prototype of the test machine is modeled, followed with a dynamic simulation using the rigid-flexible coupling analysis method presented in ADAMS software. Finally,a test machine is developed and its performance is tested through a HVC experiment of 316 L stainless steel powders.The practice shows that the mechanical energy storage-type HVC method helps to perform high-velocity compaction and that the test machine is of preferable capability of powder forming.

Key words: powder metallurgy, high-velocity compaction, mechanical design, virtual prototype
