Electric, hybrid-electric and fuel-cell vehicles have received positive response from the market due to their environmental-friendly factors. However, an electric vehicle powered by a solar energy has not yet being produced commercially because of power reliability and also high production cost. At the moment, solar vehicles are being developed for individual use, demonstration and also for research activities. For example a solar vehicle is being developed for the World Solar Challenge (WSC) 2009. Most of the mechanical components and the electrical components such as the solar panels, batteries, permanent magnet motor, controller and maximum power point trackers (MPPT) are available offthe-shelf. In this paper, the driving force characteristics of the permanent magnet motor are described. The motor's torque, speed and current characteristics are used to analyze the potential power performance of the vehicle on the road. Road test has shown that the theoretically calculated performance matches the road test results very closely.

Vehicle's low drag force is critical to achieve higher speed and for efficient energy usage. Most solar vehicles that participated in the World Solar Challenge event adopted the 'cockroach' shape which has been considered as the best shape to achieve optimum speed and aerodynamics characteristics. However, the team from University of Malaya decided to design their entry vehicle based on the profile of a box fish, said to possess an even lower drag coefficient value. This paper describes the aerodynamics characteristics numerical study of the solar vehicle using a computational fluid dynamics (CFD) code called FLUENT. The numerical computation is based on the frontal area of the vehicle and the obtained results have shown reasonable values of drag and lift coefficients when compared to ordinary road vehicles.

Usubamatov, Ryspek, Prof. Dr.; Khairul Azwan, Ismail, Dr.; Jamali, Md Sah
The basic attributes of any industrial machine are productivity rate, quality of products, as well as the cost and flexibility of manufacturing systems. Attributes of productivity are related to the theory of reliability, let alone the theory of efficiency of machines. The main attribute of reliability with any industrial machine is availability, which is the integrated index of the machine's reliability. The availability of industrial machines with complex designs should be a constituent of equations on productivity rate. This paper develops analytical equations of productivity rate with the availability of automated lines as a function of structural, technical and technological parameters of industrial machines. The equations allow for the output of automated lines to be modelled and their structures to be defined according to the level of productivity and availability.
