Study on Elastohydrodynamic Lubrication of Viscoplastic Fluid and Mechanism of Collapse and Failure of Lubricating Film
Doctor Zhang Yongbin's thesis
2000
Liu Jianping pieced together his doctoral thesis by plagiarism, mainly from Zhang Yongbin's doctoral thesis. She doesn't have her own job at all, and she makes up data at will and manipulates data artificially, which is particularly bad. Some materials are listed below:
1. Liu Jianping's Chinese abstract is actually the same as Zhang Yongbin's. She wrote Zhang Yongbin's specific work (the main contents listed in her abstract (2)-(7)) into the Chinese abstract, which is more explicit.
2. The second page of Liu Jianping's doctoral dissertation, "Research Status of Rheological Model 1.2. 1", plagiarized Zhang Yongbin's doctoral dissertation from pages 15 and 16.
3. Liu's third page, "Logarithmic Rheological Model of 1.2. 1", was copied from the dissertations of 16 and 17.
4. The Evans-Johnson model on page 5 of Liu was copied from another paper by Zhang Yongbin:
Yongbo Zhang, et al., Elastohydrodynamic lubrication model of molecular film: Part I-Analysis progress, International Fluid Mechanics Research, 2003, Vol.30, 542-557.
5. The section "Calculation of line contact film thickness 1.2. 1" on page 8 of Liu's paper is copied from page 1-3 of his paper.
6. The section "1.2.2 Calculation of membrane thickness" on page 9 of Dr. Liu's dissertation was plagiarized from pages 3-4.
7. Liu 1 1 Page "1.2.3 Current situation of theoretical and experimental research on film failure" is copied from the published dissertation page 9-1.
8. Liu 12 "10.3 the significance of this study" plagiarized the self-published dissertation 13- 14.
9. Liu 14-22 pages are probably copied from other people's works.
10. On page 22 of Liu's section "Analysis of physical conditions of lubricating film slip", a document of Zhang Yongbin, namely the document marked by Liu [125], was quoted at will, but this section was actually copied from pages 35-37 of the dissertation. Liu Biao's document [125] has nothing to do with "the physical conditions of lubricating film sliding".
1 1. Liu copied the paper from page 23, figure 2-2, page 36, figure 2-4.
12. Figure 2-3 on page 24 of Liu Zi's dissertation; Figure 2-2 on page 2 1.
13. Liu's pages 25-37 are probably copied from other people's works and copied according to Zhang's dissertation 18-27.
14. Liu copied the paper on pages 37-39 and 46-47.
15. Liu copied the paper from page 39, figure 2-page 47, figure 2-5.
16. Liu published his dissertation on page 40 of Calculation Results of 2.8 and page 48 of Calculation Results of 2.2.6.
17. Liu Di 4 1 Page "The Influence of Slip-Roll Ratio of 3. 1 on the Characteristics of Non-Newtonian Fluids", copied from the self-taught thesis page 49 "Some Typical Results of 3. 1". Among them, Liu deliberately tampered with several words: changing "limited to 2.0m/s" in Zhang Wenzhang to "less than 2.0m/s" and changing "slip-roll ratio" in Zhang Wenzhang from 0 ~ 2.06 to "slip-roll ratio S is 0 ~ 2.2"; However, these changes are simply ridiculous. "Less than 2.0m/s" means that Liu hasn't calculated the rolling speed, and I don't know what she calculated. She misinterpreted the meaning of "limited" in Zhang Wenzhang, but it was actually "equal", while the slip-roll ratio calculated by Liu was 2.2, which was impossible. In Zhang's paper, under the same working conditions, the slip-roll ratio can only reach 2.06.

Among them, Liu also made artificial random changes to the data, such as changing "the slip-roll ratio is greater than 0. 174" in Zhang Wenzhang to "the slip-roll ratio is greater than 1.0" (this random change is absurd). In Zhang's paper, "When the slip-roll ratio is 1.95, 2.0 and 2.06, the minimum oil film thickness is 40nm, 2 1nm and 1nm respectively" is changed to "When S is 1.90,1. 438+0nm and 65 In Zhang's paper, the minimum film thickness is as low as 65,438+00 nm when S=2.06, while in Liu's paper, the minimum film thickness is 65,438+00 nm.

In fact, these formulas are copied from the regression formula (3- 13) and formula (3-65438) on page 96 of her dissertation. In order to hide people's eyes and ears, she changed the variables CP, UB 1, K 1, N 1 and rth in Zhang formula into variables respectively.

75. On page 76, Liu said that she had done a lot of calculations herself, and regressed more than 65,438+000 sets of data for the maximum Hertzian pressure range of 0.75 GPA to 5.0 GPA, and regressed the formulas (5-5) and (5-6) in the paper. Her formulas (5-5) and (5-6) are very similar to those (3- 19) and (3-20) obtained by regression on page 105 of dr. zhang's paper. This phenomenon is impossible, because the maximum Hertzian pressure range of Zhang regression formula is 0.7GPa~4.5GPa, which is based on 40 sets of data regression. There are obvious differences between Liu and Zhang in regression calculation, but the regression formulas given are so similar. It can only be said that Liu made up the sentence that "the maximum Hertzian pressure range is 0.75 GPA to 5.0 GPA, and returned to 100 sets of data", which actually copied Zhang's regression formula. In order to hide people's eyes and ears, she changed the coefficient "5.809" and index "0.554", "0.78 1" and "-0.263" in Zhang's formula (3- 19) to coefficient "6.02" and index "0.56" and "0" respectively.
