COMPUTERISED CALCULATIONS OF AUTOMOBILE CLUTCH ASSEMBLY

The calculation process of automobile friction disc clutch assembly has been aided via the creation of a special computer program . Input data to the program is different parameters of the vehicle and road . The program will determine the design dimensions according to materials used for the clutch assembly parts and design parameters values. It will perform all required calculations , checkings and modifications required for the complete design regarding the friction plate,pressure plate,clutch springs and clutch shaft. Sutch a program beside helping the designer in his main job,it gives him also the possibility to study the influence of some design parameters on the assembly performance. As an example for the study of changing design parameters on the performance,a special routine is written to give the effect of changing the thickness of pressure plate on the increase of its temperature during the clutch slip . another routine is written to study the effect of road inclination angle on the clutch temperatur rise. The presented p-ogram was applied to make the calculations and analysis of the Jeep car (GAZ-69) as a real example of applications.
