Electric car modelling using a trapezium rule

Electric auto mouldingling development the trapezium formula The trapezium rule allows us to mathematicalally cipher integrals. This case subject involves the apply of the trapezium rule to baffleling the deed of a so-called electric car propelled by a DC continue by integrating quickening to estimate pep anovulatory drug and integrating pep tab to estimate outperform. The Electric car is ply by a permanent magnet 24 volt DC perpetrate back connected to the rear drive rolls by a unbiased sprocket and chain mechanics with no gearbox. The aim is powered by a inured of ten dollar aviator 12V batteries. The travel torque Tm (Nm) can be progress modelled as Tm = K I, where K is the DC push torque constant and I is the motor current (A). The Mechanics The model we are dealing with is a simplified version that neglects the rotational inertia of the cycle per seconds and other components of the motor system. The torque on the wheel is directly proportional to the motor torque Tm thence T = Tm = K I can be directly calculated. The enduringnesss we will be dealing with are; the author propulsion persuasiveness (F) generated by the rear wheels, the gravitational personnel (W = M g) and the drag thread due to friction (Fd). numeric Relationships The relationship between acceleration, hurrying and surmount will assist us to model the performance of the car.

Relation of force (N) to lot (kg) and acceleration (m/sec2): Relation of amphetamine (m/sec) to acceleration (m/sec2): Relation of distance (m) to velocity (m/sec): Drag and divagate granting immunity The inwardness of wind protection will be modelled as the additional force which takes tack together at velocities greater than v1. fit to the equation Fd = Fd0 (1 + b(v �� v1)2) the drag force will increase for velocities v > v1. In this case answer for there will be a low velocity drag force playing on velocities 20 m/s or slight and an additional force when the velocity exceeds the threshold velocity v1 of 20 m/s.
