| Course contents : | Design process - Iterative nature, design office versus method office, machine subsets and elements. Exigencies upon functionality, reliability and cost. Functionality - Dimensions, standards, interchangeability, dimensional chains; dimensional tolerances, geometrical tolerances. Link with the mechanism hyperstaticity. Roughness. Stifness exigencies. Friction : adhesion, bolts, hooping, belts, brakes ; sticking, stick-slip, wear ; how to reduce frictional effects. Design for asssembly and disassembly. Reciprocal dependance of shapes and manufacturing processes. Reliability - Forces evaluation, first design of a shaft, general reliability concepts, mechanical tests of materials, stress limit assesment, the concept of safety. Volumic strength with static and dynamic loads. Hertzian contacts. Rolling bearing calculation. | |||||
