Vehicle Speed calculation

By using Prescribed method you will be able to find vehicle speed at any Gear 
you will need to have these inputs to perform the calculation:

 1) Engine RPM (N)=2500
2) Tyre revolution/Km (M)=398
3) Total reduction of power train (Rg)=14.3856:1

 vehicle Speed formula is given by
V =Vehicle Speed in Km/hr.

 V= (N X 60) / ( M x Rg)
  =(2500 x 60)/(398 x 14.38)
  =26.19 Kmph

Calculate Tractive Effort at wheels-TE Inputs Required Torque at Wheels = 32607 N-m Tyre SLR = 0.4 meters Tractive effort (N) =  Torque at Wheels  /  Tyre SLR = 32607/0.40 =81518.4 N Related Link https://autocal1.blogspot.com/2020/06/calculating-torque-at-wheels-inputs.html

Max permissible Tractive effort due to Ground Adhesion- TEGA To Calculate Max TE due to ground adhesion  you will need to have following data as input. Mue =Coefficient of friction between road and wheel =0.7 (Dry road) =0.4 (wet surface) GUV( Gross vehicle Weight)= 9500 Kg Formula: Tractive effort= GVW X Mue=9500 x 9.81 x 0.7 = 65236.5 N
