A New Gerotor Design Method With Switch Angle Assignability
Gerotor is generated by an oval shape generating curve, which is attached to a large pitch circle rolling on an inside smaller one. For gerotor design, existing methods are able to handle arc-based ge...

Optimization of the Loaded Contact Pattern in Hypoid Gears by Automatic Topography Modification
Systematic optimization of the tooth contact pattern under load is an open problem in the design of spiral bevel and hypoid gears. In order to enhance its shape and position, gear engineers have been ...

Thispaper introduces the technique of separation, which replaces a designoptimization problem with a set of subproblems. This separation issimilar to decomposition but does not require a second-level coordination.We identify conditions under which this separation yields an exactsolution and other conditions under which the error can bebounded. We show that the decision-based design framework, which seeksto find the most profitable design, can be separated intoa sequence of subproblems. We also apply separation to amotor design problem and demonstrate how the surrogate constraints andobjective functions affect the solution quality. These results indicate away to apply the principles of decision-based design to designprocesses.
