Numerical Aspects of Vehicle Performance is Course Designed for Mechanical, Automobile Engineering Students to Analyse and Calculate Vehicle Performance. In this Course Students will able to calculate Parameters of Vehicle Performance such as Power required to propel vehicle, Engine Power, Various Resistance Offered By Vehicles such as Air or Wind Resistance, Rolling Resistance, Gradient Resistance, Total Resistance, Tractive Effort & Difference Between Traction & Tractive Effort. Students will able to analyse important aspects of vehicle such as Maximum Acceleration, Gradiability, Drawbar Pull. Depending upon the type of Automobile Vehicle Students will able to find out Tractive Effort available at different gears. Students will decide using numerical analysis whether automobile vehicle will able to climb up gradient at specific speed. The motion of a vehicle moving on a level road is resisted by aerodynamic forces, known as wind or air resistance, and road resistance generally termed as rolling resistance.In addition to these two types of resistances, the vehicle has to overcome grade resistance when it moves on a gradient, because the weight of the vehicle is to be lifted through a vertical distance. Hence the power required to propel a vehicle is proportional to the total resistance to its motion and the speed.
