Unformatted text preview: made between the design phase and the operation phase. At the design stage, the designer is expected to specify clearance values that must be met by the mechanism in operation, i.e. taking into account load and temperature conditions. Their effects on part geometry must in turn be computed or simulated so that deflection or strain values can be obtained for both loads and temperature. Corresponding total part deviations can then be used with the Jacobiantorsor model to predict clearances in operation. Product design validation is then completed by comparing the predicted clearance in operation with the corresponding design requirement. The link between product and process validation is at the identification stage of the design phase (fat arrow in figure 2). Indeed, this is where clearance values at assembly (for process validation) and clearance values in operation (for product validation) are defined. Obviously, these two parameters are not independent. The next section addresses specifically the issue by proposing a “PLM synthesis procedure” enabling the design...
