Abstract
In this paper, the investigation and analysis of a pin in the pusher of the induction furnace was carried out numerically. First, by simulation of the pusher mechanism in MATLAB's SimScape/SimMechanics toolbox, the force on the pin was calculated in the worst-case condition of the device. Then, the pin was simulated and analyzed in the finite element software Abaqus. The obtained results showed that with the increase in axial and radial clearance, the maximum amount of stress and the area with high stress distribution intensity in the pin increased. Also, the increase in axial clearance causes the stress distribution to be drawn to the supports. With the increase in radial clearance, the arc forming the contact area of the pin and supports decreases and the loads are concentrated at the lower area and will have an effect of impact loading. Also, increasing the length of the involved support for zero radial clearance has no effect on the stress distribution on the pin. Therefore, excessive length only results in additional costs.
