摘要：

In　the　process　of　shell　design　of　a　100kW　single　screw　expander,　the　fundamental　research　on　the　screw　chamber　walls　thickness　is　still　lacking.　Thin　wall　may　cause　deformation　and　the　damage　possibility　of　the　inlet　passage.　Thick　wall　will　increase　the　weight　of　the　expander　and　led　to　assembly　problem　and　transportation　inconvenience.　In　this　paper,　static　finite　element　analysis　on　cast　shell　of　the　100　kW　single　screw　expander　was　carried　out.　By　calculating　stress　distribution　and　deformation　of　the　expander　shell　under　1.5　times　of　the　design　pressure,　the　authors　find　the　thickness　of　gate　rotor　chamber　walls　and　inlet　passage　walls　as　15　mm　is　acceptable,　but　the　thickness　of　screw　chamber　walls　should　be　at　least　35　mm.　©　(2014)　Trans　Tech　Publications,　Switzerland.
