A procedure for centrifugal axial clutches (CENTAX) design was developed. This procedure consists in the use of three hardwired independent programs through a routine developed in Matlab. Initially the designer fills a table in Excel with parameters necessary to the simulation to be done by the Matlab. These parameters are: data of the initial geometry of the clutch, data of the materials to be used in the construction of the clutch, engine power curve, or the set from the clutch will receive power and data from the joint load, that is, of the system which the clutch will transmit power. In such a way, when initiating the program in Matlab, this will execute the reading of the initial data in Excel, that in set with the Simulink will process them returning through graphs from coupling force, rotation and transmitted torque, the results of the simulation. In the case of the results are not in accordance with the specifications, the designer has the option of redimensioning the clutch modifying the initial values in Excel and restarting the program in Matlab. This part of the procedure could be repeated until the answers of the system are in accordance with its objectives. A chosen time the dimensions of the clutch, the designer initiates the Solid Works, as the drawing technician in 3D and the plants are parametric with the same spread sheet in Excel, these already will be redimensioning and duly quoted, ready for the impression and sending for the production line and therefore, the sequence of tests.
