The invention provides a cam profile optimization method, a wave generator and a harmonic reducer, and the optimization method comprises the steps: dividing a cam profile into a long-axis profile section, a transition profile section and a short-axis profile section which are sequentially connected according to a polar coordinate angle, according to the meshing coefficient, the modulus, the stress separation coefficient and the stress separation angle of the flexible gear, a supporting function of the long-axis contour section is obtained through calculation; according to the deformation coefficient and modulus of the flexible gear, a supporting function of a short-axis contour section is obtained through calculation; calculating the coordinate and slope of the first intersection point and the coordinate and slope of the second intersection point according to the first contour function and the second contour function; and determining a support function of the transition contour section according to the coordinate and slope of the first intersection point and the coordinate and slope of the second intersection point. The stress of the long shaft contour section and the short shaft contour section on the flexible gear can be ensured to be minimum at the same time, and the cam can be prevented from generating salient points in the area between the long shaft and the short shaft. Therefore, the comprehensive stress amplitude of the whole flexible gear is optimal, and the risk of failure of the flexible gear is reduced.

The invention relates to the technical field of aero-engine air inlet channel design, and discloses a low-turbulent-flow air inlet supporting plate structure which comprises a supporting plate body with symmetrical airfoils, and is characterized in that the supporting plate body is continuously twisted by 180 degrees along a spanwise path from a hub connecting end to a cartridge receiver mounting end of the supporting plate body. The torsion enables the wing-shaped rear edge of the casing mounting end and the wing-shaped front edge of the hub connecting end to form a spatial inverted corresponding relation, so that a Mobius flow channel for guiding smooth transition of airflow is formed. By means of the unique topological structure, the flow separation phenomenon can be fundamentally eliminated, the flow separation angle is not larger than 8 degrees, the total pressure recovery coefficient is increased to 98% or above, and the distortion coefficient of the supporting plate is remarkably reduced. Finally, the uniformity of air flow entering the air compressor is effectively improved, and the overall air inlet efficiency and performance of the engine are improved.
