Abstract Scope |
There is a growing interest in developing space mechanisms that overcome the engineering challenges associated with long-term space flight/operation, e.g. the need for lubrication, mechanism activation, and performance including wear resistance, with material selection being of critical importance. Compliant mechanisms have emerged as a strong candidate for replacement of multi-component mechanical assemblies with monolithic-type designs potentially overcoming many of these inherent challenges. For example, intrinsic flexures may replace multi-part hinges thereby eliminating assembly, lubrication and backlash, as well as potentially reducing overall manufacturing costs. The principal merits of Bulk Metallic Glasses (BMGs) have been well documented over the last 40 years, with a wide number of metallic glass families shown to exhibit high specific strength, elasticity, corrosion resistance, hardness, and wear resistance.
This paper presents details of a current research project investigating implementation of BMG materials into compliant mechanisms for long-term space-based missions. |
