The case study reports on the analysis of the tolerance stack for a Smart Solenoid End Assembly (see Fig. 13). In carrying out the study the stack failure severity can be taken as S = 4 and the customer required a 'worst case' analysis. The primary design requirement was to control the plunger displacement to 0.8, 0.2 mm.

The analysis of the components in the tolerance stack using the TCE software is tabulated below in Table 1.
