Abstract
A first harmonic runout simulation hub includes a measuring disc and a clamping portion detachably fixed together, in which the clamping portion is fixed in the middle of the measuring disc; 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 a measuring cylindrical surface having a preset axial length and a bus parallel to an axis of the first positioning hole, the radial distance between the axis of the measuring cylindrical surface and the axis of the first positioning hole is greater than a preset value, and circular runout test values on the measuring cylindrical surface are preset first harmonic runout values.
