| Abstract:The analysis and investigation for side plate connecting bolt fracture of both domestically-produced and imported air coolers on diesel engine PA6B was carried out. And by finite element analysis, improvement measures were put forward. Analysis for several measures was done respectively , and the optimal scheme was determined and used in the repairing of the initial produced air coolers. The subsequent air coolers were produced in accordance with the optimal design scheme and such kind of failures had been solved thoroughly since then. |
