Stress Analysis Project
Abstract
Stress Project
1. Introduction The clutch used in automotive applications is generally a single plate dry clutch. In this type the clutch plate is interposed between the flywheel surface of the engine and pressure plate.
1.1 Operation & Methodology: Basically, the clutch needs three parts. These are the engine flywheel, a friction disc called the “clutch plate” and a pressure plate. When the engine is running and the flywheel is rotating, the pressure plate also rotates as the pressure plate is attached to the flywheel. The friction disc is located between the two. When the driver has pushed down the clutch pedal the clutch is released. This action forces the pressure plate to move away from the friction disc. There are now air gaps between the flywheel and the friction disc, and between the friction disc and the pressure plate. No power can be transmitted through the clutch. When the driver releases the clutch pedal, power can flow through the clutch. Springs in the clutch force the pressure plate against the friction disc. This action clamps the friction disk tightly between the flywheel and the pressure plate. Now, the pressure plate and friction disc rotate with the flywheel.
2. Problem Statement Our analysis is based on the clutch plate of an automobile which is also known as the clutch friction disc. Our objective is to calculate the maximum stresses on the clutch disc by using the octahedral and maximum shear stress criteria. We are using the analytical as well as the computational methods and we will compare them.
3. Analytical Method We are using the clutch disc of a Corolla GLI 1.6 VVTI Engine Car for our analysis. The data collected from different sources is under:
Outer Diameter: 212.6mm (Outer Radius Ro= 106.3 mm)
Inner Diameter: 139.5mm (Inner Radius Ri= 69.75 mm)
Centering Diameter: 26.6mm (Centering Radius= 13.3 mm)
