Abstract: The propel compensation connecting level as the key components of the Boomer series driving trolley, the structral strength and fatigue life of the Boomer 281 trolley are infulenced directly by the ones of the propel compensation connecting lever.According to the location and structure of connecting lever, the statics analysis is conducted so as to looking for the danagerous section that located in area of the connecting lever and turn the shaft vertical intersection. The boundary conditions of the connecting lever is discussed based on establishing the 3D model of the connecting lever, besides that, the finite element analysis is adopted to calcuate the stress and strain values of the turn the shaft of connecting lever. The research results in this paper can provide some reference for improving the equipment maintenance maangement level.

Key words: Connecting lever, Structural strength, Finite element analysis
