Material selection: An important parameter in the design of high-speed linkages

Abstract Numerous studies in the literature have demonstrated that members of high-speed linkages should be designed with high strength-to-weight ratios and high stiffness-to-weight ratios. By satisfying these criteria, the designer is able to minimize the troublesome elastodynamic phenomena associated with demonstrates the advantages of using ultra high strength fiber-reinforced composites in this design field by simulating the dynamic responses of flexible four bar linkages manufactured in three different materials (steel, aluminum and a graphite-epoxy laminate). The mechanisms are analyzed using a displacement finite element model and the equations of motion are solved by numerical integration.
