STRUCTURAL OPTIMIZATION OF REAR BUMPER FOG LAMP PUNCHING MACHINE

Presently, plastics are widely used for car exterior and interior trims however, with the growing importance of reducing vehicle weight, plastics application to body and chassis parts is ever on the increase. In the past the interior and exterior trim was glued. With the scope to increase the safety and for execute a cogging process with reference was built these machines. Some of the applications include deep drawing operations, blanking & punching riveting, stamping & pressing, powder compacting, etc. Apart from precision and accuracy, hydraulic presses have strong frames, made of ultrasonically tested steel frames. Frames are fabricated from prime steel plates of proper thickness for greater strength & rigidity. Moreover, there is different kind of guiding arrangement to suit the needs of various applications. The machines are fully automated, operator is necessary only for load/unload the bumpers. Machines help to satisfy customers with excellent Quality & Safety standards for manufacturing hydraulic presses in a relatively short span of time. Special purpose machines are now extensively used in automotive industry to cope up with manufacturing volume demands with quality and accuracy. In this paper, Optimized design is done with the help of Bi directional Evolutionary Structural Optimization Technique (BESO). Components are analyzed and restructured to meet structural, flexural requirements. Optimized design is targeted to fulfill the flexibility and huge change over requirements for various bumper models to assembly with reduction in weight of structural parts.
