An Educational Visual C++ Program Aid for Understanding

Abstract

An educational program was developed to assist graduate and undergraduate students to comprehend the influence of a number of tractor parameters on its performance. The program was written in Visual C++ programming Language. The program provides an intuitive user interface by linking tractor and tire databases, and the potential interaction with traction models and performance parameters. The program offers an educational help and clarification to most of the steps and variable parameters. The program was validated by comparing predicted performance variables with the results of Al-Hamed and Al-Janobi (2001) program for bias-ply and radial tires. The same numerical values were obtained for the performance variables. The developed program was also illustrated by selecting an example Massey Ferguson MF 3090 tractor from the tractor specification database to show the various stages of predicting tractor performance parameters. The program has proven to be very user-friendly and efficient to meet the requirement
