The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00013 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

要約

The performance of vertical herringbone grooved journal bearings has been experimentally conducted to investigate the effects of groove patterns on the pumping sealing of the bearings. A test rig has been designed and fabricated for this purpose, and different herringbone groove patterns on the shafts have been tested at rotational speeds of about 200–2100 rpm. The aluminium shafts are of 46.2 mm diameter and the transparent sleeve (to enable visual observation of liquid lubricant between the shafts and the sleeve) was made of a perspex pipe of 120 mm length. Pressure tappings were made on the sleeve to obtain the pressure pro.les along the shafts. The asymmetrical S-L-S-L (short-long-short-long) pattern, with a groove length ratio of 4.5:5.5, and the symmetrical L-S-S-L (long-short-long-short) pattern, with a groove length ratio of 3:7, show the most promising performance among the herringbone groove patterns considered.
