Abstract

See full text

A constant stress solid disk rotor of a flywheel has an outer shape having a plane-symmetric upper surface and lower surface, an outer circumferential radius b, and a rotation center thickness h0, and includes a thickness decreasing region which decreases monotonously in thickness from a rotation center to a connection radius a and a constant thickness region located on an outer edge of the thickness decreasing region and having a constant thickness ha from the connection radius a to the outer circumferential radius b. Shape parameters including the outer circumferential radius b, the rotation center thickness h0, the connection radius a, and the outer edge thickness ha satisfy an equation below. Here, ν is a Poisson's ratio of a rotor material.
