Study of Traction Characteristics of a Low Multi-Purpose Vehicle

Vehicle traction performance is the vehicle's ability to move against the drag force that exists when the vehicle is operating. The power of the vehicle engine influences the capability of the vehicle, the choice of transmission level and ratio, and the type of transmission used so that sufficient driving force is required to overcome the drag force that occurs in the vehicle. This paper discusses the study of the traction characteristics of low multi-purpose vehicles. The study was carried out by calculating aerodynamic force, rolling resistance, and drag force due to grade angle at various velocities and gradeability to determine the total drag force. The study continued by calculating each gear transmission's driving force, net driving force, and maximum vehicle speed. The results show that the aerodynamic force has the lowest drag force, and the drag force due to the incline angle produces the highest drag force among the three drag forces that occur in the vehicle. Vehicles with 1 ^st gear transmission can move up to 50% gradeability, followed by 2 ^nd , 3 ^rd , and 4 ^th gears. Vehicles can drive well using 5 ^th and 6 ^th gear transmissions on flat roads.
