Disc Brake Test Bench: Braking Torque and Temperature Rise

Approx. component budget: Rs. 12,000 - 17,000

Objective

Measure how braking torque, stopping time and disc temperature change with applied force and initial speed.

What you will build

A motor-driven shaft with a flywheel, a scooter disc and caliper, a brake lever with a force gauge, a speed sensor and an infrared or thermocouple temperature sensor.

Results you can expect

• Stopping time and deceleration vs brake force
• Braking torque
• Disc temperature rise vs number of stops
• Brake fade behaviour

What you will learn

Brake design, conversion of energy to heat and friction behaviour, key topics in automotive testing.

Tools and notes

IR sensor + Arduino, speed sensor, Excel. Use a strong frame and guards, and do not touch the hot disc.

Resume points from this project

• Built and tested Disc Brake Test Bench: Braking Torque and Temperature Rise; objective: measure how braking torque, stopping time and disc temperature change with applied force and initial speed.
• Measured and analysed stopping time and deceleration vs brake force and braking torque; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
