Abstract:

This paper evaluates the impact caused by inertia force of beam with non-uniform mass distribution. The impact is made by non-uniform beam falling on supports. Then, stresses of this model are analysed and optimized by using position of the supporting forces, mass distribution and convenient geometry. Results of this study, present the solutions for better design of the beam and having the highest resistance for it, and also have some suggestions for better geometry until the beam get stronger. In this paper, useful relations between bending stress on the beam due to inertia shock, mass distribution and position of supporting forces are demonstrated. The study reveals some interesting findings related to the best bar configuration in terms of geometrical design, design of supports location, mass distribution and use of multi-material components. The studied problem takes place in many of the mechanical systems such as exhaust and suspension systems and etc.
