Lab Assignment 2: What is the maximum disk temperature of the disk? Objective - Mountain Bike with a disk brake and a rider is going down a 30 degree steep hill with a steady speed of a few mph, while engaging the disk brake. By using SolidWorks, study the maximum disk temperature. Brake Disk and Brake pad spec: Brake Disk Outer Diameter - 20cm Brake Disk Inner Diameter - 2cm Thickness – 0.7cm Brake disk material – stainless steel Total heat flux on brake pad area – 10000W/m2 Heat transfer coefficient on the exposed area – 746W/m2-K Environmental temperature – 298K Brake Pad OD – 20cm Brake Pad ID – 15cm Extended angle – 60 degree With the provided brake disk requirements and assumptions, the thermal study on SolidWorks showed that the maximum disk temperature is XXX

Unformatted text preview: FEM Lab Assignment ‐ 2 Mountain Bike with a disk break. Rider is going down a 30o steep hill with a steady speed of a few mph, while engaging the disk brake. The total heat flux from the brake to the brake disk is 10000 W/m2. Cooling is facilitated by air blowing over the exposed brake disk with a heat transfer coefficient of 746 W/m2‐K. Given: Disk is solid (do not model the complex shape shown in the figure) with an OD of 20 cm, ID of 2 cm and a thickness of 0.7 cm The material is stainless steel There are two brake pads applied at opposite sides of the disk The footprint of the brake pad on the disk has an ID of 15 cm, OD of 20 cm and extends over an angle of 60o....
