Project
Aim:-
To prepare atechinical report of simulation of BAJA-Terrain(ATV)under different conditions.
Objective:-
Carry out the system-level simulation of an all-Terrain vehicle and prepare a technical report explaining the model properities&comments on the result.
1)Study the baja ATV model without dashboard.
2)Study the baja ATV model with dashboard.
3)Study the baja ATV model without dashboard.
4)Study the baja ATV model with dashboard
Introduction:-
Transmission which transmits the power engine to the wheels through the shafts it consists 4 types mainly
1) Manual transmission
2)Continous transmission
3)Semi automatic transmission
4) automatic transmission
All-terrain vehicle:-
An all-terrain vehicle(ATV) is defined as a motorized off highway vechicle designeed to travel on four low-pressure and haveing a seat designed to the operator for steering control.
Study:-1
By using simulink model of CVT consists of signal builder,generic engine,motion sensors,vehicle body,vehicle transmission and system configuraction blocks and etc.The CVT subsystem includes transmission blocks input and output shaft inertia and motion sensors.The vehicle body subsystem includes vehicle body block,double drum break and tyres. The mass of the vehicle As 250kgs and 2 axles which connects 4 wheels accordingly.
Simulation model:-
CVT sub system model:-
Vechicle body sub system model:-
Signal builder input:-
CVT output:-
CVT shaft output:-
CVT ratio:-
Engine Toruqe speed:-
Study:-2
The given below figure shows the baja ATV with dashboard which consists throttle meter and brake input in the dashboard instead of giving input through signal builder and reset the blocks and the subsystemare common in the above baja ATV model without dash board.The main concept of using dashboard is study the results by using varying the input vallues of break and throttle and which shows the velocity and speed of the engine.The gear ratio is maintained.
CVT model with Dashboard model:-

By using simulink model of CVT consists of signal builder,generic engine,motion sensors,vehicle body,vehicle transmission and system configuraction blocks and etc..The CVT subsystem includes lookup tabels and transmission blocks input and output shaft inertia and motion sensors.The vehicle body subsystem includes vehicle body block,double drum break and tyres. The mass of the vehicle As 250kgs and 2 axles which connects 4 wheels accordingly.
A lookup table is an array of dadta input that maps input values to output values if the lookup table does not explicitly define the input values simulink can estimate an output valus using interpolation or rounding.
The above input and throttle input is given by step time which depends on the runtime and varies accordingly by using lookup table gear ratio which takes as input gear ratio and obtained outputvallues.
Study:-4
CVT ratio:-
CVT shaft speed:-
The given below figure shows the baja ATV with dashboard using of lookup table which consists throttle meter and brake input in the dashboard instead of giving input through signal builder and reset the blocks and the subsystemare common in the above baja ATV model without dash board.The main concept of using dashboard is study the results by using varying the input vallues of break and throttle and which shows the velocity and speed of the engine.The gear ratio is maintained.As the gear ratio varies the torque also varies gear ratio is directly propostional to the torque which increases by the gear ratio.At the max torque the speed and velocity is decreases.
Conclusion:-
The overall process the simulation we are obsereve the models of both with dasbboard and without dashboard and i verifing the all vallues of the varition of velocity and shaft speed and Cvt ratio and torque and input then signal builder and lookup tables observed the all vallues of the models.
