It has sufficient strength to withstand increases in internal pressure and flexibility so that it can expand and contract because it has an accordion-like structure with many-plates. In the hydraulic excavator, the bellows exhaust pipe connects the engine and the muffler. It is heated by high-temperature exhaust gas and also exposed to thumping vibration from the engine and the body. To ensure pipe reliability in these harsh conditions, we have to develop a technique to evaluate the bellows strength accurately in the design phase. In this study, on the basis of theoretical formulas listed in the Japanese Industrial Standards (JIS), we developed a bellows analytical model by using single shell elements with equivalent stiffness. Also, we modified the model by considering the contact effect to achieve higher accuracy. Then we evaluated the bellows exhaust pipe model which contains modified bellows models by comparing calculation results and measurements in the modal testing and the tensile shear test. From the results, we confirmed that the developed model can imitate the vibration characteristics and stress distribution accurately. In the next step, we will develop a prediction technique for dynamic stress on the bellows that occurs when the excavator is operating."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282680492007301","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163287"}],"foaf:name":[{"@language":"ja","@value":"川下 道宏"},{"@language":"en","@value":"KAWASHITA Michihiro"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Hitachi,Ltd., Hitachi Research Laboratory"},{"@language":"ja","@value":"(株)日立製作所 日立研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680492007300","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163288"}],"foaf:name":[{"@language":"ja","@value":"大野 孝之"},{"@language":"en","@value":"OHNO Takayuki"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Hitachi Construction Machinery Co.,Ltd., Research Div."},{"@language":"ja","@value":"日立建機(株) 研究本部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680492007297","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163289"}],"foaf:name":[{"@language":"ja","@value":"星 暁生"},{"@language":"en","@value":"HOSHI Akio"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Hitachi Construction Machinery Co.,Ltd., Research Div."},{"@language":"ja","@value":"日立建機(株) 研究本部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680492007299","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163290"}],"foaf:name":[{"@language":"ja","@value":"伊藤 健児"},{"@language":"en","@value":"ITO Kenji"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Hitachi Construction Machinery Co.,Ltd., Research Div."},{"@language":"ja","@value":"日立建機(株) 研究本部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680492007296","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163291"}],"foaf:name":[{"@language":"ja","@value":"下平 貴之"},{"@language":"en","@value":"SHIMODAIRA Takayuki"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Hitachi Construction Machinery Co.,Ltd., Research Div."},{"@language":"ja","@value":"日立建機(株) 研究本部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282680492007298","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000303163292"}],"foaf:name":[{"@language":"ja","@value":"宍道 康彦"},{"@language":"en","@value":"SHINJI Yasuhiko"}],"jpcoar:affiliationName":[{"@language":"en","@value":"UniCarriers Co.,Ltd., Product Development Div."},{"@language":"ja","@value":"ユニキャリア(株) 開発本部"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"21879761"}],"prism:publicationName":[{"@language":"en","@value":"Transactions of the JSME (in Japanese)"},{"@language":"ja","@value":"日本機械学会論文集"}],"dc:publisher":[{"@language":"en","@value":"The Japan Society of Mechanical Engineers"},{"@language":"ja","@value":"一般社団法人 日本機械学会"}],"prism:publicationDate":"2015","prism:volume":"81","prism:number":"828","prism:startingPage":"15-00114","prism:endingPage":"15-00114"},"reviewed":"false","url":[{"@id":"https://www.jstage.jst.go.jp/article/transjsme/advpub/0/advpub_15-00114/_pdf"}],"availableAt":"2015","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Modal%20analysis","dc:title":"Modal analysis"},{"@id":"https://cir.nii.ac.jp/all?q=Modeling","dc:title":"Modeling"},{"@id":"https://cir.nii.ac.jp/all?q=Simulation","dc:title":"Simulation"},{"@id":"https://cir.nii.ac.jp/all?q=Optimization%20probrem","dc:title":"Optimization probrem"},{"@id":"https://cir.nii.ac.jp/all?q=Strength%20design","dc:title":"Strength design"},{"@id":"https://cir.nii.ac.jp/all?q=Modal%20analysis","dc:title":"Modal analysis"},{"@id":"https://cir.nii.ac.jp/all?q=Modeling","dc:title":"Modeling"},{"@id":"https://cir.nii.ac.jp/all?q=Simulation","dc:title":"Simulation"},{"@id":"https://cir.nii.ac.jp/all?q=Optimization%20probrem","dc:title":"Optimization probrem"},{"@id":"https://cir.nii.ac.jp/all?q=Strength%20design","dc:title":"Strength design"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1361981470851729408","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Modal Assurance Criterion"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204092729728","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Stress Analysis of Multilayer Bellouws"},{"@value":"多層ベローズの応力解析"},{"@language":"ja-Kana","@value":"タソウ ベローズ ノ オウリョク カイセキ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679742034304","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Study on Hydroformed Bellows.
