Stability Analysis for Buoyancy UTeM’s Amphibious Hybrid Vehicle (AHV)

The buoyancy of the amphibious hybrid vehicle is depending on the parameter of the bottom hull body to keep it afloat every time. Based on the Archimedes principle, the weight of the object float is equal to the volume of water displace. When stimulates on the water surface, there will always resistant that affect the stability of the vehicle. Besides, the stability level of the AHV is very important to ensure the vehicle is on the stable condition and has the ability to face the rollover and pitch effect. Therefore, bottom hull body parameter of the vehicle is not just make it floating, but plays the important role to keep it in the stable state during face the rolling and pitching effect

Design, Analysis and Fabrication of Chassis Frame for UTeM Formula VarsityTM Race Car

Two chassis frames of race car have been designed and developed according to the specifications of UTeM Formula VarsityTM 2012 (FV2012). FV2012 is an event to test students’ analytical and technical skills in designing, analyzing and fabricating a race car. In this section of report, the design and development of the chassis frame of the race car are presented. Commercial computer aided design (CAD) software is used in design and analysis stages. Once the results of the analysis are desirable, actual chassis frame fabrication is performed using available materials. Standard processes of cuttings, fittings and welding are performed in chassis frame mock up and fabrication. The product is later assembled together with suspension systems, steering linkages, brake systems, engine system, and drive shaft systems. The accomplishment in final fittings and assembly of the race car and its reliability demonstrate an excellent design for manufacturing (DFM) practices of the chassis frame

Design Of Formula Varsity Race Car Suspension Upright

This paper presents the design of a suspension upright for Formula Varsity race car. CATIA V5 R16 CAD software was utilized to generate the 3D model of the final upright design. Aluminum alloy grade 6061-T6 was selected for the upright construction material due to its low density and good mechanical strength as well as wide availability in different sizes. Structural analysis using finite element method (FEM) was implemented to analyze the structural strength. CATIA V5 Generative Structural Analysis workbench as used in the analysis. Results from the structural analysis shows that the upright design has a factor of safety of 12.1, which theoretically proved that the structure is able to perform safely as per design requirement. A part from that, through utilization of aluminum alloy as the upright material, the weight of the component is able to reduce up to 57.5% compared to the upright used in 2010 UTeM Formula Varsity race car. Thus, the new upright design is able to provide the crucial weight saving needed for an efficient race car without compromising its structural strength and safety

Concurrent material selection of natural fibre filament for fused deposition modeling using integration of analytic hierarchy process/analytic network process

The employment of natural fibres in fused deposition modeling has raised much attention from researchers in finding a suitable formulation for the natural fibre composite filaments. Moreover, selection of suitable natural fibres for fused deposition modeling should be performed before the development of the composites. It could not be performed without identifying selection criteria that comprehend both materials and fused deposition modeling process requirements. Therefore, in this study, integration of the Analytic Hierarchy Process (AHP)/ Analytic Network Process (ANP) has been introduced in selecting the natural fibres based in different clusters of selection concurrently. The selection process has been performed based on the interdependency among the selection criteria. Pairwise comparison matrices are constructed based on AHP’s hierarchical model and super matrices are constructed based on the ANP’s network model. As a result, flax fibre has ranked at the top of the selection by scored 19.5% from the overall evaluation. Flax fibre has excellent material properties and been found in various natural fibre composite applications. Further investigation is needed to study the compatibility of this fibre to be reinforced with a thermoplastic polymer matrix to develop a resultant natural fibre composite filament for fused deposition modeling

UTeM`s Amphibious Hybrid Vehicle: Development of Hybrid Electric Propulsion System

This paper presents the preliminary development of hybrid electric propulsion system for amphibious hybrid vehicle (AHV). AHV is developed as a transportation that can operate on land and water which to be used by rescue team in rescue operations. AHV is driven by motor electric on the land, and while on the water, AHV is propelled by internal combustion engine (ICE) and at the same time, ICE is use as generator to generate the electricity to recharge the battery pack. The main factors that need to be considered in order to develop a hybrid electric propulsion system is the power required by batteries to transmit to the motor electric to move the vehicle. An optimum hybrid electric propulsion system should have minimum fuel consumption, simple to develop and high reliability. Matlab Simulink Analysis based on the mathematical modelling is conducted to determine the power required before the fabrication take place. The design of hybrid electric propulsion is then fabricated by combination of ICE and electric motor. Finally experimental analysis is conducted to determine its reliability and durability
