Abstract

This invention relates to a friction winch design method based on parameter matching diagrams for high-altitude wind power generation. It is based on the Euler formula for flexible body friction, theoretically derived to construct a mathematical model of a clamped cable friction transmission. Parameter normalization is applied, and a design parameter matching diagram is drawn. Wheel pressure constraint lines and transmission efficiency contour lines are superimposed on the diagram. Finally, the optimal design parameters are determined using the graphical intersection method. Specifically, the method includes the following steps: (1) friction winch mechanism design; (2) core mathematical model construction; (3) generation of the equivalent friction coefficient-clamp pressure-rope tension mapping curve; (4) introduction of constraint conditions; and (5) drawing of a three-parameter coupled design diagram. This invention significantly improves design efficiency, ensures design reliability, provides global parameter optimization, and exhibits good versatility and scalability.
