Abstract
A simulation hub includes an end plate, a clamping portion and a measuring disc, in which the clamping portion and the measuring disc are both detachably fixed to the end plate; the clamping portion includes a first positioning hole for positioning and clamping, the first positioning hole is a cylindrical hole, and the cylindricity of the first positioning hole is smaller than a preset value; the outer circumference of the measuring disc includes at least a measuring cylindrical surface having a preset axial length and a bus parallel to an axis of the first positioning hole, and circular runout test values of the measuring cylindrical surface are preset first or second harmonic runout values; and the outer diameter of the measuring cylindrical surface is adapted to the inner diameter of the first positioning hole.
