Abstract

Elastomer is a natural or synthetic polymer having elastic properties and the main components for the fuel delivery system. It can undergo degradation of their physical properties when directly contact with biodiesel. The specimen of elastomer need to be prepare first before proceed with the experiment. However, the tensile test specimen cutting equipment in the market are expensive, heavy and consume more time for shipment. Thus, to overcome this problem, the tensile test specimen cutting equipment has been invented. This machine are mini in size, portable, durable and consume reasonable costs. The purpose of this study is to develop conceptual and detail design of tensile test specimen cutting equipment and to fabricate the prototype of tensile test specimen cutting equipment. Literature review must be done to make sure the specimen need to cut according to ASTM D412-06 standard to ensure the test is valid. The design process planning are needed to identify, search and assemble all the information related in product design specification. From the morphological chart, few conceptual designs were made and evaluated using Pugh concept selection method to obtain the final design. The final design is then modeled by using Solidworks. The functionality of the 3D model was analysed using finite element analysis. The purpose of this analysis was to determine the product's strength and define the critical stress area so that design improvements can be made to achieve a safety factor of more than one for the entire model. Then further process of fabrication was executed.
