Safety CAE Finite Element Calculation for Pressure Cooker of Plateau Field Kitchen Unit

Abstract

The core equipment of plateau field kitchen unit is pressure cooker for staple food, the safety and reliability of which are the key of this project, and therefore, mechanics modeling analysis is carried out. The working theory of pressure cooker is to increase the boiling point of water by enhancing the pressure inside the cooker, so as to speed up the cooking process. In fact, the pressure cooker is a small-scale pressure container when using, normally its working pressure reaches some tens and hundreds Kpa. People pay more attention to its safety and dependability. The traditional way to increase the bearing capacity of container is usually to thicken the wall of container, by doing so, not only the manufacturing cost is increased, but also the weight, thus it is inconvenience in using and bringing. Therefore, in order to make optimum structural design of pressure cooker, reliable analysis on mechanical strength and stiffness are carried out.
