Abstract

Regardless of rising attention to the issue of game related injury in rugby, great evolution of sport equipment went on, and this led to progressive development and improvement on the design of testing rig. This project will develop a hitting system thus, the study of a fluid power will be a part of this project. Pneumatic control circuit is a type of fluid control circuit where it will give the efficient force and acceleration compare to the previous hitting machine. In order to develop the project there is a few aims that need to be emphasis, where the first thing is to design the new concept for a hitting system for head concussion test rig, the second aim is to develop a prototype of hitting system for head concussion test rig. Last but not least, to conduct testing on the hitting system and validate the testing rig with head model. The methodology applied to conduct this project is generate trough research analysis, research design, component selection, design for manufacturing, and prototyping and testing. Where the development of the project is by using House of Quality, Morphological chart, Pugh selection method, conceptual design, product design specification, and prototyping and testing. Next the development of the project were assisted by engineering software in order to produce the best solution for the test rig with high efficiency that can stimulate the actual impact during the real game. The hitting system will generate the force that execute the vibration data for analysis. The performance standards has an impact (9.5 m / s, 58 J) which is same with the collision experienced by the Rugby player (5 ± 1 m / s, 50-60 J). Thus the test rig accomplish all the standard stated where the speed of the actuator has been analyse where it can reach up to 11 m/s. Moreover the speed of the actuator can be set by follow the SMC standard which can be improvise by using flow control valve. Defining the standard needs, and infusing the standard from the IRB and NOCSAE into every aspect of the design process. The test rig needs were transcribed into engineering characteristics by the method of Morphological chart to organize the solutions for every sub problems. The design alternatives generated were undergone Pugh selection method, where every design alternatives were compared to each other and the best design was selected for further development. This whole process has certainly infused the product design specification into every aspect of the design process.
