Finite Element Modeling of Compressor Discharge Tubes
نویسندگان
چکیده
Discharge tubes in hermetically sealed refrigeration compressors are often a source of fatigue failure which is not serviceable and necessitates the replacement of the compressor. The finite element method can be used to model the discharge tube to help prevent such failures and to reduce costs by optimizing the tube. This investigation considers techniques for modeling discharge tubes with finite elements and predict1ng the dynam1c motion and dynamic stresses in the tube during compressor operation. The relative merits of direct versus modal time integration techniques are studied specifically to evaluate which techniqne is most accurate and efficient.
