Multi-criteria assessment of multispeed planetary gearboxes
A methodology of comparison and determination of the most promising gearboxes is presented. Calculation analysis of multispeed planetary gearboxes with four degrees of freedom developed by Mercedes, General Motors and KATE is made. Parameters of gearsets, necessary for calculations, are estimated with the use of patent data. For a comprehensive evaluation of gearboxes quantitative indicators are entered. A quality complex indicator of gearboxes is proposed, calculation of which is based on a multicriteria assessment of the basic data obtained in the calculated analysis.
