[Example] Lightweight design of rotating parts considering rigidity and manufacturing requirements.

Introducing the lightweight design of rotating components while maintaining rigidity in their initial shape, taking into account various manufacturing requirements!

For rotating components such as wheels, advanced design is required that takes into account not only mechanical properties like rigidity, strength, and vibration characteristics, but also various manufacturing requirements and aesthetic considerations. Here, we present a case study of a motorcycle road wheel that was designed with manufacturing requirements in mind to achieve weight reduction. We established a Multi-Point Constraint (MPC) to maintain rotational symmetry while considering manufacturing requirements such as "the overall shape must be moldable" and "must have a certain minimum wall thickness." First, we created an initial model that is one-third periodic symmetric using rotational copying. Then, we added load and constraint conditions, outputting the data as Nastran data, and subsequently created and added the MPC for maintaining rotational symmetry using the post-processor TS Studio. As a result, we achieved approximately an 11% weight reduction while maintaining a rotationally symmetric shape.
