Model Based Design of Pressure Profiles for Pyrotechnic Actuator using SPH Method & LS-OPT Solution

The design of Pyrotechnic Pistons is subjected to many unknowns, its methodology sometimes consists of many experiments in a trial & error process. This paper presents the design process of such a device. In this work a model–based design process was applied using LsDyna © model and LsOpt © optimized solution obtaining upper and lower bounds for the pressure profiles of a pyrotechnic piston device. The numerical solution decreases the number of required experiments in the design process and cuts its costs.
