Abstract: Important drawbacks of Coriolis experimental setup and devices are their multiple parts and cost to own. Simplicity, traceability, and measurability are the major concern. This paper presents a preliminary design process of Coriolis acceleration experimental device to visualize the effect of Coriolis and enable the calculation of acceleration components to facilitate students for a better understanding of this phenomenon. This is realized through a slidable collar with a marker and accelerometer attached on it and a rotating rod that shows a visible yet erasable mark from the marker’s path. The design process went through typical engineering design processes such as morphological study, functional decomposition, and Pugh chart. Next, Finite Element Analyses (FEA) were performed to determine the mode shapes, followed by analytical calculation of the dynamic reaction experienced by motor. In addition, this kit provides opportunity for students to manually calculate the actual acceleration component based on theory learnt which is considered innovative. The use of controllable motor for rotating the rod could vary the travelling path of the marker, subsequently diversify the problems for student to solve.
Keywords: Coriolis acceleration, inertia frame, rotating rod, travelling path.
