چکیده

The present manuscript gives the description of findings which took importance during the design and analysis of the structure of heavy duty hauler machine ordered by Gol-e-Gohar iron ore complex in Iran. Stress and deformation analysis was indeed the heart of the project and the key of its success. The challenging problem of evaluation of value and behaviour of active loads was taken under consideration precisely and all participated external forces were included in analysis. Since the present case is a moving structure, the loading evaluation should be included in all critical experienced conditions through the operation. The inertial forces due to acceleration and road bump have the governing role and have been evaluated and considered in analysis. After precise and complete evaluation of external loads and applying the correct boundary conditions, the simulations for stress analysis have been performed in ANSYS. The main findings of the present study were the optimized decision for the geometry of several important load carrying elements and appropriate reinforcement of the risky positions which was the result of the correct knowledge of the mechanics of problem. Finally, the structure was manufactured with the total weight of about ۳۸ ton and load carrying capacity of ۱۲۰ ton including the dynamic effects. After succeeding in the initial loading, the operational loading in real conditions in mine ramp has been carried out gradually and the machine is currently working in desired predicted form.
