Design optimization of the modified planetary carrier

This paper aims to design a new model of the third-stage carrier assembly used in a planetary gearbox as a single part component with improved strength and fatigue life properties and lower production costs. First, the mounting carrier assembly is subjected to static, fatigue, and modal analysis, an...
