Safety evaluation for oven structures using parametric method
설계 변수법을 이용한 밥솥 체결 구조물의 안전도 평가
- Published : 2008.08.31
The structures of induction heating type pressure rice cooker are consisted of oven. top heater plate and locking ring. Because the pressure is applied to their structures, those should be necessary to do the safety evaluation. In this paper, structure analysis is performed for oven structures by using finite element method and as a results, optimal thickness is achieved. Especially, analysis fur anisotropic layered material is performed because oven is made of both stainless steel and aluminum. And both von Mises and Tsai-Wu failure criterion are applied for safety factor. Parametric method is used in order to get the optimal thickness for oven and top heater plate.
