1Planetary Gear Profile Modification Design Based on Load Sharing Modelling显示文摘In order to satisfy the increasing demand on high performance planetary transmissions, an important line of research is focused on the understanding of some of the underlying phenomena involved in this mechanical system. Through the development of models capable of reproduce the system behavior, research in this area contributes to improve gear transmission insight, helping developing better maintenance practices and more efficient design processes. A planetary gear model used for the design of profile modifications ratio based on the levelling of the load sharing ratio is presented. The gear profile geometry definition, following a vectorial approach that mimics the real cutting process of gears, is thoroughly described. Teeth undercutting and hypotrochoid definition are implicitly considered, and a procedure for the incorporation of a rounding arc at the tooth tip in order to deal with corner contacts is described. A procedure for the modeling of profile deviations is presented, which can be used for the introduction of both manufacturing errors and designed profile modifications. An easy and flexible implementation of the profile deviation within the planetary model is accomplished based on the geometric overlapping. The contact force calculation and dynamic implementation used in the model are also introduced, and parameters from a real transmission for agricultural applications are presented for the application example. A set of reliefs is designed based on the levelling of the load sharing ratio for the example transmission, and finally some other important dynamic factors of the transmission are analyzed to assess the changes in the dynamic behavior with respect to the non-modified case. Thus, the main innovative aspect of the proposed planetary transmission model is the capacity of providing a simulated load sharing ratio which serves as design variable for the calculation of the tooth profile modifications.IGLESIAS Miguel FERNáNDEZ DEL RINCóN Alfonso DE-JUAN Ana Magdalena GARCIA Pablo DIEZ Alberto VIADERO Fernando 2015Chinese Journal of Mechanical Engineering2015,28,4:9
2Hepatic flow is an intraoperative predictor of early allograft dysfunction in whole-graft deceased donor liver transplantation: An observational cohort study显示文摘BACKGROUND Early allograft dysfunction(EAD)after liver transplantation(LT)is an important cause of morbidity and mortality.To ensure adequate graft function,a critical hepatocellular mass is required in addition to an appropriate blood supply.We hypothesized that intraoperative measurement of portal venous and hepatic arterial flow may serve as a predictor in the diagnosis of EAD.AIM To study whether hepatic flow is an independent predictor of EAD following LT.METHODS This is an observational cohort study in a single institution.Hepatic arterial blood flow and portal venous blood flow were measured intraoperatively by transit flow.EAD was defined using the Olthoff criteria.Univariate and multivariate analyses were used to determine the intraoperative predictors of EAD.Survival analysis and prognostic factor analysis were performed using the Kaplan-Meier and Cox regression models.RESULTS A total of 195 liver transplant procedures were performed between January 2008 and December 2014 in 188 patients.A total of 54(27.7%)patients developed EAD.The median follow-up was 39 mo.Portal venous flow,hepatic arterial flow(HAF)and total hepatic arterial flow were associated with EAD in both the univariate and multivariate analyses.HAF is an independent prognostic factor for 30-d patient mortality.CONCLUSION Intraoperative measurement of blood flow after reperfusion appears to be a predictor of EAD;Moreover,HAF should be considered a predictor of 30-d patient mortality.Pablo Lozano Lominchar Maitane Igone Orue-Echebarria Lorena Martín Cristina Julia Lisbona María Magdalena Salcedo Luis Olmedilla Hemant Sharma Jose Manuel Asencio JoséAngel López-Baena 2019World Journal of Hepatology2019,11,9:4
