Abstract: In the design of a mechanical component for a mechanical device driven by a feedback controlled electric motor, the user is enabled to easily know how the properties of mechanical component affect the generation of abnormal vibrations of the mechanical device. In a design assist apparatus (1), the processor (11) is configured to set a plurality of parameters of a mathematical model of an analysis target component selected from one or more mechanical components (24, 56, 58) forming the mechanical device, compute a pole of a transfer function of the mechanical device associated with one or more vibration modes of the mechanical device according to the parameters, and create a stability determination diagram including an isoline of a real part of the pole of the transfer function.

Abstract: Provided is a flexible shaft coupling which demonstrates a high performance in transmitting torque and accommodating positional deviations, and is yet highly durable. A first elastomer member (82) having a relatively high rubber hardness is circumferentially interposed between a first claw (32) of a first shaft coupling member (20) and a second claw (62) of a second shaft coupling member (50), and a second elastomer member (84, 86) having a lower rubber hardness than the first elastomer member is interposed between a surface portion (end surface) (30) of the first shaft coupling member (20) and the second claw (62) and/or between a surface portion (end surface) (60) of the second shaft coupling member (50) and the first claw (32).
