KBS-selection of universal joint used in agricultural machinery

Abstract In this study, a knowledge-based system was developed to a id in selection of universal joint, which is used in agricultural machinery (KBS_UJ). In selection of the universal joints, it is very important to choose the suitable mechanism for the agricultural machinery, which is going to be used. A main programme was written by using the AutoLISP and DCL languages. According to the Turkish Standards in different categories, maximum torque and maximum power, critical revolution number and power capacities of various tube profiles, joint open length depending on the tube profile type, joint closed dimensions and joint tube dimensions were determined and selected joint was drawn in 2D. The system was tested on joint producer in order to validate the decision obtained. The system can be helpful to producer, farmer or safety working
