DESIGN AND ANALYSIS OF ROLLER CONVEYOR FOR WEIGHT OPTIMIZATION BY USING COMPOSITE MATERIAL

In the present work, an attempt is made to reduction in weight of existing roller conveyor by optimizing the critical parts of (e.g. Roller,) conveyor without hampering its structural strength. The existing Roller conveyor designed is considered for this project work. The dimensions being 6000 mm length, 34 inch above ground and inclined at 6 degree with the ground and the weight to be carried by the conveyor - 360Kg (360 kg with added factor of safety). This is the weight of the largest component to be transported over the conveyor. The conveyor would norma lly encounter gradually applied loads while the components are lowered by hoist. For reasons of safety, a `sudden load’ is already considered during its design phase. Static analysis of roller of existing conveyor is carried out find out maximum deflection & stress. Then Optimization is carried out by modifying the dimensions of roller .Then analysis of optimized roller are carried out to find out maximum deflection & stress. As such, the existing roller conveyor structure is tested for mechanical strength over the shop - floor while a trial is taken using optimized designed rollers of assembly and with the real - time components of the excavator. Upon completion of the experimentation, the assembly is observed for any visible damage to the conveyor units. The u nits are measured for their height, especially at the central region along the length of the unit with a general purpose retractable measuring tape. The recorded measurement does not highlighting any sag induced in the unit during the experimentation phase . As the rollers in which changes are made in existing design are standard (the weight of the physical model is slightly more than the optimized model values). So made easily available in market.
