SHIFTER MECHANISM DESIGN FOR FSAE MOTOR SPORTS VEHICLE JCU

This report provides a design analysis of a replacement’s shifter mechanism for the 2014 model JCU Motorsports FSAE vehicle. Common FSAE shifter mechanisms were researched and reviewed to provide a better understanding of the needs required. A design approach was constructed to ultimately design a mechanism that conformed to all existing constraints and FSAE rules. Realistic load cases were identified and employed in the FEA analysis of the design. Supporting hand calculations were developed, proving the analysis to be accurate. Results showed the shifter mechanism does not fail under infinite life, with some parts of the design having a reasonably high safety factor, ensuring stability.

Review on Design & Development of Go-Kart Steering System

Go-kart is one of the motor sports where racing of bunch of vehicles are compete each other. This paper is written after completion of manufacturing and complete assembly. Following paper consist of diagrams, calculations and results from actual models of steering and electrical systems. Steering system is one among crucial areas in designing of go kart as even the slightest of improvement in response of this technique could reduce the lap time and help to succeed in the driving force beyond the finishing line to win an edge. Thus, steering has got to be reliable enough such the driving force could have the entire control over the kart even within the toughest tracks. On the other hand, any failure in system could lead to serious injury or loss to the driver and the team. This paper is written with an aim to enhance a steering mechanism of go kart and overall responsiveness and control. This paper covers most of the concepts of steering mechanism of knowledgeable go kart. With the assistance of this paper one could understand and manufacture complete steering assembly individually. The paper consists of theory, formulae, calculations, diagrams and simulation results which give top to bottom understanding of knowledgeable go kart steering mechanism.

DESIGN AND MANUFACTURE CHASSIS AND BODY OF SIMPLE GOKART USING AUTOMATIC CLUTCH AND 7.5 HP ENGINE POWER

Go-kart is a variant of a simple and small open-roof four-wheeled vehicle for motor sports. Go-kart usually races on small scale circuits. Go-kart racing is usually considered a stepping stone for motor sports that are higher and more expensive. The design of the karts is carried out by mechanical engineering students of the University of Riau based on the size of karts in general. The chassis is made of pipe with ASTM A53 pipe specifications with a tensile strength of 240 MPa with a dimension of length of 6.22 meters, an outer diameter of 33.40 mm and an inner diameter of 30.02 mm. Body building is done with fiber with a catalyst mixture ratio of 1:45. The process of painting with a ratio of primers and hardeners is 1: 4, and clear and hardener 4: 1. A kart with a chassis mass of 7.09 kg and a passenger of 70 kg has been produced, with dimensions of length 1100 mm, width of 610 mm, and distance between axes of 1050 mm. This karting uses the 1994 Astra grand engine with 7.5 HP of power, 6000 rpm rotation and 20 kg mass. The transmission system used is a double automatic type.

Expenditure Behaviour and Satisfaction in Motor Sport Events

This chapter examines the differences in expenditure and satisfaction among first-time and repeat spectators at a motor sports event. A structured questionnaire was developed, and data were collected on site via 318 interviews carried out during the 2019 Federation Internationale de l'Automobile World Rally Championship in Sardinia. Data were analysed by running a series of descriptive analyses, independent t-tests, and regression analyses. The results show that repeaters are more satisfied and spend more when compared to first timers. This study helps to extend the scientific debate related to the growing, and often still inconsistent, comparison of first-timers' and repeat visitors' behaviours by offering insights from a motor sports event, where little research exists so far. Based on the findings, managerial implications are discussed, and suggestions for further research are given.
