Abstract

Fuzzy theory and multi-objective optimization technology were applied to design fuel injector pump plunger spring based on consideration on its force condition. The mathematical model for the multi-objective optimization design was built under the objective of the maximal fatigue safety coefficient, the minimal weight and height, with the design variable of wire diameter d, mean diameter D and working circle n. Then, the fuzzy solution of multi-objective optimization were use to solve the model. Practical example of calculation shows that, the plunger spring’s weight, wire diameter and spring height increases a little but the fatigue safety coefficient improves by 10.35% and 12.45% respectively, and the mean diameter reduced obviously.
