Various forms of the products manufactured which could either be symmetric or asymmetric, the stacking of the asymmetric parts are either done manually which is a time-consuming job or by installing robots which are costly. To overcome this problem, part feeders are introduced to stack the parts in a specific orientation. A Rocker arm, an asymmetric (irregular) component having more number of stable poses, has been considered for this research. The objective of this work is to achieve the desired orientation with the existing trap system. The parameters which are concentrated while orienting the parts are part geometry, part weight and angle of the trap inclination for effective part motion in the trap. In order to get accurate results the analysis are carried out with software simulation. The vibration analysis was carried out using dynamic simulation software. The comparison shows an appreciable relationship to each other. The obtained values help to improve the performance of the part feeding system and to improve the productivity of the component.
