CALCULATORS / APPLICATIONS

Vehicles and ground transport

Longitudinal vehicle models with declared road and drivetrain losses.

mass, slope, acceleration, rolling and drag loads → wheel torque, tractive force

motor RPM, reduction, wheel radius → vehicle speed, ratio required

mass, slope, speed, rolling resistance, efficiency → wheel and battery power

usable energy, road-load model, drive scenario → range, energy per distance

speed, deceleration or traction, reaction time → braking and total stopping distance

normal loads, friction, acceleration or slope → maximal tractive force, slip threshold

rider/motor power, cadence, reduction, wheel size → crank torque, chain force, assisted speed estimate

sprung mass, spring and damping, motion ratio → ride frequency, sag, travel demand

wheelbase, track, steering angle → turning radii, steering-angle relationship

speed profile, mass, efficiency, charge acceptance → recoverable energy, power limits
