摆线内啮合齿轮泵转子的应力和应变状态的研究
Published 2013-01-01“…Using the urea pump(a cycloid pump) of SCR exhaust emission system as the object of study,the stress and deformations of the pump during the operation process by using the finite element method and the ANSYS program are analyzed.According to the research,it shows that the two kinds of load which the rotor received are respectively the torque of the input shaft of the inner rotor and the hydraulic load resulted from the pressure of the liquid between the tooth displacement chambers.The tooth stresses are not even and both the strain and deformation trends are different are also discovered.Therefore,the axial gap between teeth and radial clearance between the pump body and rotor occur which leads to the internal leakage of pump and seriously influence the pump working pressure and the volume efficiency and life of the pump.Least but not last the paper illustrates a way to determining the load range for pump: the loading of the pump should not higher than stress(equal to the maximum pressure stress of PEEK,that is,and at the same time,the radial clearance and the axial clearance should not exceed the extreme values and assumed for a particular size of the pump,that is and.…”

STUDYING AND CALCULATION OF THE POTENTIAL ENERGY FOR TWO OF MOLECULES [TRIMETHYL GALLIUM AND TRIETHYL GALLIUM,] BY SEMI EMPIRICAL PROGRAMS
Published 2023-01-01“… In this research, the potential energy and vibration frequencies for two of an non-liner molecules [ (C3H9Ga) and (C6H15Ga)] have been studied and calculated by using the semi-empirical theoretical programs in method (MNDO/PM3) where the geometric space shape of two molecules has been calculated by using initial and final matrices that include bonds length, the angle between bonds, dihedral angles and the charge of each atom in the two molecules, which have been drawing a curved of potential energy per molecule where the drawing was adopted to change the length of the bond (Ga-C) in the each molecule compared to what is obtained from the values of energy and it was total energy calculate for each molecule at equilibrium distance was (-553.044 eV) at equilibrium distance (1.8327 ) and (-1003.53726 eV) at equilibrium distance (1.8344 ) for the two molecules, respectively, and from the carve of the potential energy was the spectroscopy dissociation energy per molecule account it was equal to (4.508 eV) and (4.70991 eV) respectively . …”

Outage probability based power allocation and relay selection algorithm in cooperative communication
Published 2013-10-01“…The relay selection and power optimization of multi-relay cooperative communication network under a joint sum power constraint was considered.A low complexity lay selection and power allocation algorithm was also pro-posed in amplify-and-forward cooperative network aiming at minimizing the probability of system outage.In this scheme,optimal power allocation among source and relay nodes was conducted.According to the SNR,an optimal relay node set was selected and a power allocation factor leading to lower system outage probability was obtained by steepest descent method.This algorithm did not need large quantity of l statistical information and equal power condition.It can obtain the best set of relay nodes under optimal power allocation only by solving the arranged matrix on the basis of Sig-nal to Noise Ratio.Simulation results show that the proposed relay select and power allocation algorithm,under the same conditions,compared in the outage probability in erent relay node set among several algorithms,achieves better performance in outage probability and power efficiency.…”
