How Finite Element Calculations Improve Hyper Compressor Performance and Lifetime Available to Purchase

The basic design of actual hyper compressor was performed around 40 years ago, in a time when the use of computers was limited and most of the design calculations were made by hand. In our days most parts are significantly improved with the support of finite element calculations. In this paper the benefits of such an optimization will be highlighted by several examples like the compressor central valve, the flexible rod coupling or even the overall compressor vibrations. In addition the modeling of some for hyper compressors typical manufacturing processes like autofrettage will be discussed.
