1. Introduction



Quarter model of end bell case and end cap.
Restraints are Symmetry and fix vertically on the flange inner edge. Also radial restrint on the connector port of the fend bell.
Pressure loads on all exterior surfaces.
Contact surface pairs: 1. mating flange surfaces (global), 2. two each plug lands (node-surface contact, no penetration)



Note:

Do not base your design decisions solely on the data presented in this report. Use this information in conjunction with experimental data and practical experience. Field testing is mandatory to validate your final design. COSMOSWorks helps you reduce your time-to-market by reducing but not eliminating field tests.
