specific Embodiment 2
[0086] according to figure 1 As shown, the present invention provides a three-objective optimization method for aero-engine rotor assembly based on three-point weighing, comprising the following steps:
[0087] Step 1: For centering and tilting of the leveling and tilting platform 4, ensure that the centroid of the assembly reference plane is concentric with the rotation axis of the 4-axis system of the leveling and tilting platform, and ensure that the assembly reference plane is parallel to the plane of the leveling and tilting platform 4, so that The assembly reference is the bottom surface of the bottom rotor, the axis of rotation of the air bearing shaft system 2 is the Z axis, the intersection of the axis of rotation and the upper surface of the upper air bearing plate 2a is the origin of coordinates, and a straight line passing through the origin of coordinates and parallel to the base 1 is used is the X-axis, and the Y-axis is a straight line passing through the coordi...
