| 1 | An efficient design tool based on FEM for evaluating effects of components properties and operating conditions on interaction of tire with rigid road显示文摘It is noted that any variation in operating conditions has a considerable effect on the tire/road interaction. Furthermore,choosing a range of proper values for carcass stiffness is very essential for both tire safety and effective driving action. In this work,an elaborated 3D model fully compliant with the geometrical size of radial tire 185/60 R15 is worked up, for evaluating the effects of components properties and working conditions on deformation and stress/strain fields created inside the tire. For the simulation, the tire structure is assumed to be composed of tread, carcass ply, and bead. The mechanical behavior of rubber as main component of tire is described by Mooney-Rivlin material model. The comparison of the obtained results and laboratory tests demonstrates the validity and high accuracy of analysis. | Moslem Namjoo Hossein Golbakhshi | 2015 | Journal of Central South University2015，22，1： | 7 |
| 2 | Numerical simulation of tire/soil interaction using a verified 3D finite element model显示文摘The compaction and stress generation on terrain were always investigated based on empirical approaches or testing methods for tire/soil interaction.However,the analysis should be performed for various tires and at different soil strengths.With the increasing capacity of numerical computers and simulation software,finite element modeling of tire/terrain interaction seems a good approach for predicting the effect of change on the parameters.In this work,an elaborated 3D model fully complianning with the geometry of radial tire 115/60R13 was established,using commercial code Solidwork Simulation.The hyper-elastic and incompressible rubber as tire main material was analyzed by Moony-Rivlin model.The Drucker-Prager yield criterion was used to model the soil compaction.Results show that the model realistically predicts the laboratory tests outputs of the modeled tire on the soft soil. | Namjoo Moslem Golbakhshi Hossein | 2014 | Journal of Central South University2014，21，2： | 6 |
| 3 | Thermo-structural analysis on evaluating effects of friction and transient heat transfer on performance of gears in high-precision assemblies显示文摘The high precision assemblies with considerable radial interference should be accompanied by heating and cooling processes.However,the mechanical properties of metals are greatly affected by thermal operations.So,for evaluating the stress distribution and distortion of teeth profiles in a gear/shaft assembly,a transient thermal analysis is necessary for finding the change in mechanical properties.The friction on the contact surface is another important parameter in interaction of the gear with the shaft.Evaluating the gear stress and deformation fields for several modes of heat transfer and friction coefficients showed that the maximum radial or tangential stresses on contact surface of the joint may have more than 8%increase by increasing friction coefficient;while the intensity of heat transfer at cooling stage has lower effect on stress distribution. | Hossein Golbakhshi Moslem Namjoo | 2017 | Journal of Central South University2017，24，1： | 3 |

| 10 | A direct probe of the evolutionary history of the primordial universe显示文摘Dear Editors,Direct measurements of the evolution of the scale factor of the universe a(t)have played central roles in cosmology.By measuring the relation between the distance and redshift of galaxies,Hubble and Lamaitre[1]discovered the expansion of the universe,providing the first evidence for the Big Bang model.Such measurements have been done in exquisite precisions in modern days using the type Ia supernovae as standard candles,leading to the discovery of the late time acceleration of the universe[2].These measurements laid | Xingang Chen Mohammad Hossein Namjoo Yi Wang | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，10： | 0 |
