Abstract

This publication deals with the optimization of a linear generator (LG) intended for use in a hybrid power train design for a vehicle. The system in which the LG is integrated is called free-piston linear generator (FPLG). The free-piston linear generator is able to convert chemical energy into electrical energy by using a combustion process. By optimization of the LG it is possible to reduce the fuel consumption significantly. In this publication the function and the characteristics of the free-piston linear generator will be explained first. Then the surrounding system and its effect on the FPLG and the linear generator will be pictured. This is important for the understanding of the adaptation and optimization of the linear generator to the system. After this the way of the optimization and adaptation process is pictured. It is based on a 2-D and a 3-D FEA model which is controlled by a database software. After the presentation of the calculated results a comparison between the calculation and a physically existing linear generator is presented. In the next chapter the expected fuel consumption based on a systemsimulation is illustrated. At the end of the publication a summary is given.
