I have to design a braking performance test bench for Toyota Corolla. For that i need to have equivalent mass/ inertia of the car. I have just started my work. I could'nt find any data about engine and flywheel transmission dimensions.
1. Kindly give me some guidelines in which i have to approach this project
2.I have figured out in a paper following data
mass(equivalent)=del(rotational inertia factor)* mass of vehicle
and then this del estimates to del=1+0.04+0.0025G2 G-Overall gear ratio
can we use this estimation for any vehicle or just electric vehicles?
3. Where I can get data for dimensions if I want to calculate the inertia using cad model?
4. "if I use the total resultant force on the vehicle to be used for getting a Torque value using wheel radius and then use longitudinal acceleration for calculating angular accleration and then divide Torque with Angular accelration to get total rotational inertia" will this give the Inertia Equivalent for the car
Hello Faizan,
For testing the various performance criteria of cars usually a setup called "Chassis Dynamo-meter" or popularly known as "DYNAMO" is used in which Brake test is one of the facility. Try looking for more information about the dynamo and you should find what you are looking for.
Best luck!
