An interpolating reproducing kernel particle method for two-dimensional (2D) scatter points is introduced. It eliminates the dependency of gridding in numerical calculations. The interpolating shape function in the interpolating reproducing kernel particle method satisfies the property of the Kronecker delta function. This method offers a mathematics basis for recognition technology and simulation analysis, which can be expressed as simultaneous differential equations in science or project problems. Mathematical examples are given to show the validity of the interpolating reproducing kernel particle method. © 2014 Chinese Physical Society and IOP Publishing Ltd. Source

A two-dimensional axisymmetric viscoplastic thermal-mechanical coupling finite element model was established with welding parameters and thermal-physical properties of materials to numerically simulate the continuous driven friction welding of ring-shaped 35Cr2Ni4MoA high-strength steel workpieces. The changes of temperature field, stress-strain field and axial shortening were analyzed, and the amount of axial shortening and flash shape during welding were measured and compared with the calculated results. The results show that the simulated flash shape and axial shortening in the welded joint agreed well with the experimental ones. The developed finite element model will be beneficial to formulate proper friction welding procedures. Source

In order to address the poor continuity of the three-dimensional blade morphology caused by the conventional design method that is based on the projection theorem for isoclinic angles, we present a strategy for designing the blade thickness of the hydraulic torque converter (TC) with the characteristics of the National Advisory Committee for Aeronautics (NACA) airfoil. By defining the subsection constraints of the NACA airfoil, the designed blade can meet the fluid-structure interaction requirements of the hydraulic TC, and confirm its airfoil function. In addition, based on the airfoil function and the rules for a ruled surface, we derived the blade thickness and normal thickening direction, and then obtained the blade thickness vector of the hydraulic TC, which realized the blades thickness design (called the normal thickening method, for short). Taking the blade design of the twin-turbine TC as an example, we used this method and the projective method for isoclinic angles to establish the model. By comparing the computational fluid dynamic (CFD) simulation and rack test results, we found that by using the proposed method, the design parameters of the blades could be effectively reduced. The designed drop-like blades could improve the efficiency of the hydraulic TC, and an automatic blade design can be realized. © 2016, Editorial Board of Journal of Harbin Engineering.
