A good agreement was obtained between the simulation and experimental results. The method was then applied to a double-row tapered roller bearing (DRTRB) to analyze the complex coupling behavior of its roller-raceway. The ball-disk tribotest shows that the wear coefficient rises with the increase of load and sliding velocity, in which thermal effect plays an important role. As to the friction-wear behavior of roller-raceway, the dimensionless mild wear coefficients under 4 kN and 5 kN are 4.51×10−9 and 1.06×10−8, respectively. Further study reveals that the contact stress coupled by thermal effect is obviously larger than the uncoupled and a larger load will result in higher contact pressure and produce more friction heat. As a result, the temperature on the friction interface rises to 100.5°C from 50.5°C when the load changes to 10 kN from 4 kN, and the wear rate increases to 2.45×10−3 μm/s from 1.60×10−4 μm/s. Moreover, the temperature and wear rate increase with the rise of slip ratio, and the growth rates decrease when the slip ratio reaches 0.3.","PeriodicalId":118501,"journal":{"name":"2018 9th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124187915","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}

The results reveal that the critical dewetting stress increases with increasing the particle-matrix interface fracture surface energy, or decreasing the radius of the filled solid particles. In other words, it is more difficult for the particle-matrix interface to fail as the critical dewetting stress increases. Finally, the conclusions obtained from the developed expression are consistent with the typical uniaxial tensile test results of hydroxyl-terminated poly butadiene (HTPB) propellant, which indicates that the developed expression of the critical dewetting stress is valid. Furthermore, the test results also indicate that the effects of loading temperature and strain rate on the dewetting are mainly due to the variations of the parameter in the critical dewetting stress with different loading conditions.","PeriodicalId":118501,"journal":{"name":"2018 9th International Conference on Mechanical and Aerospace Engineering (ICMAE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127135948","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}
