Availability Evaluation of An Agricultural Machine (A Numerical Approach)

In present paper, we consider an agricultural machine, namely, tractor as a system and its parts-steering box, break, clutch, automobile engine, cooling system and gear box as subsystems. Mathematical modeling of the system is carried out with the help of Markov method and governing differential equations are solved numerically by using Runge-Kutta method of order four. Taking constant failure and repair rates of different subsystems, the availability of the systems is evaluated. Results are analyzed with the help of graphs.
