Abstract
This study tries to obtain the spring constant of welded metal bellows through
experimental and numerical method respectively. The prediction of spring constant plays a great
role in the design and application of the welded metal bellows. To derive the spring constant of the
bellows, we employ commercial package to build up 2 axi-symmetric FEM models by using plane
42 and shell 51 elements. In the experiment, we use UTM to measure the spring constant of the
bellows. And, the predicted spring constant resulting from the analysis is compared with the
experimental one to discuss the rationality of spring constant analysis. The analytical results
correspond well with experimental data and hence explaining the validity of FEM model.
