In this paper, the Two-Step design method was applied successfully for the vibration reduction of a T-shaped plate structure and each design step was verified consistently by both FEM and hammering test. Especially, it was confirmed that a newly-devised FRF test method with damping sheet attached on the test-specimen can simulate a structure with heavy damping ratio of 0.1 and show the good agreement with the FRF calculated by FEM.","PeriodicalId":211622,"journal":{"name":"Transactions of the Society of Automotive Engineers of Japan","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121399166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance engine thermal efficiency, it is important to improve the engine anti-knock quality and to decrease the engine cooling heat loss.

This paper describes the thermal flow in the engine by using CAE and a single cylinder engine. It is shown that CAE can simulate engine thermal flow quantitatively. CAE can also demonstrate that cooling the upper part of the liner on exhaust side gives large effect on improving the anti-knock quality.
