Tiivistelmä
The goal of the thesis is to strengthen and analyze the strength of latest model of Protcorb’ s 26-disc-shaft, including static and fatigue in details. Moreover, the deflection is determined to avoid collisions during the operation. Subsequently, the structure of the shaft is developed in order to decrease the material usage and raise the inside cross-area of the inner channel.
The static analysis is done by two methods, which are handled by MathCad and Finite Element Method by SolidWorks Simulation. In the analysis, the Von Mises stress and its safety factor are defined by both methods. Moreover, the deflection is determined by Simulation. The stress-based method is applied to define the fatigue lifetime and safety factor. Thus, The dimensions of the shaft are adjusted without changing the design to developing the structure .
The result shown that there was not any failure and collision during the operation. After the structure is developed, the volume of the shaft without the channels decreased by 46%. The inside area of the updated channel increased by 71%, however, the material usage of the channel rose by 89%. Overall, the volume of entire updated shaft is 428708394.38 cubic millimeters which is an increase of 35%.
