Efficiency Sensitivity of Two-Stage Planetary Gear Transmission System Based on Graph Theory
This paper first establishes the graphic model and basic circuit equation of dual planetary gear transmission system based on modified complex joint picture representation method and basic circuit method. And then according to this model analyses the rotating relation and torque relation of dual planetary gear transmission system deduces the calculation formula of transmission rate efficiency. The sensitivity of each gear ratio to transmission efficiency is defined with the method of sensitivity analysis. By calculation and analysis, the influence degree of each gear ratio on transmission efficiency is obtained. The result can provide a basis for the design and optimization of dual planetary gear transmission system.
