−Automotive transmission efficiency measurements are usually performed on purpose-built rigs. A simple model was developed for calculating the overall transmission efficiency of passenger cars by using a chassis dynamometer. Wheel power and engine output were measured, and these values were used for calculations. The proposed method can only be employed for vehicles with manual drive because it...

What does the invention do? This invention presents a modular system of units that can drive, brake, steer and suspend an electric vehicle. These units are also referred to as “Robot Wheels” because they are autonomous elements that can be connected to any electric vehicle chassis. Each unit (Fig.1) includes an electric motor, a steering element, a suspension arm and a connector. The system fit...

OBJECTIVES The present study aimed to investigate the illicit drug use patterns of long-distance truck drivers. This population is considered to be a special interest group in terms of drug-driving research and policy due to high rates of use, involvement of drugs in truck accidents, and the link between drug use and work-related fatigue. METHODS Qualitative interview data were collected from...

This study evaluates different strategic courses of action concerning the secondary transportation sector in Hyrcanian forests of Iran. The decision support method Analytic Hierarchy Process (AHP) has been utilized in the assessment of different strategies in truck selection. The assessments are based on the opinions of a group of experts in Iranian forest industries. Results showed that the tr...
