Analysis of Deformation and Stress Distribution for Spring Eardrum in the Clutch by the Method of Moire Interferometry 2011-36-0117

The basic function of the clutch, transmitting torque when running, interrupting the flow of power between the engine and gearbox in the changing gears and stopping and protecting the engine and transmission against overload and dampen vibration transmission. The plateau clutch with spring membrane is the system used today. The modern clutches are small and save space in the engine compartment reducing the total weight of transmission, minimizing the resistance to rotation of the motor, providing less mechanical losses. The construction and assembly of the membrane spring clutch assembly is very important, since misalignment of reeds could result in chatter or vibration in clutch pedal, along with the hard drive of the pedal, which can also generate a deformation of the components and thus premature wear of the clutch. The displacement of the diaphragm spring clutch actuation promotes a change in the distribution of stress and strain on your profile as well as the components associated with spring, and the misalignment of the reeds causes this distribution is not uniform. The shadow moiré technique can help to assessment the deformation and stresses on the surface of the membrane spring. Conventional techniques of extensimeter and computer simulation (using FEA tools) of the drive spring are used as a basis for comparison between the results obtained by moiré in order to provide a validation of the technique.
