The Simulation of Dynamics and Consumed Fuel on Rotary Inertia of Vehicle

摘要

According to formula we can simulate the driven force and acceleration of a car.The mechanical formula is used to obtain torque value and theory dynamics is used to driven force.The driven force increases when torque increases and tire diameter decreases.Torque increases when power increases and rotation decreases.Acceleration raises when torque raises and it reduces when its weight raises.It is valued that the economical efficiency about consumed fuel under different power.9 times of efficiency promotion are attained before vehicle arrives 0.5 h,on the other hand 2 times of little efficiency promotion has been attained in driving time between 0.5 h and 1 h even after 1 h.
