This article is about casting process of tensioner pulley bracket, which includes solidification simulation, mould filling simulation and defect forecast, using ViewCast software. The scale and location of the shrinkage defects were shown in simulation results. Solidification results demonstrated that the casting defects were not eliminated by the casting technology. The optimized scheme was obtained by replacing and adding chills. The optimization scheme was calculated and the simulation results shown that the reasonable casting process was obtained and the process has been proofed by the productive practice.

The V-method foundry is an advanced casting technology compared with traditional sand casting. The Pro/E software was used to generate three-dimensional model of cast parts. The solidification process of the automotive axle casting with V-method foundry was simulated by the numerical simulation software, ViewCast. The location and scale of the shrinkage defects caused by the original process were predicted. According to the simulation results, the position of the flange round cooled too fast, which blocked the feeding passage of the round near sprue. The reason was that solidifying sequence was unperfected. The casting process was optimized by means of adding runner and chill. Progressive solidification can be obtained and the shrinkage defects can be eliminated or transferred by the improved technology. The reasonable casting process was obtained and the process has been proofed by the productive practice.

“…The traditional single scale structure simulation is unable to analyze the large-scale civil engineering structure fatigue damage. Based on the material multi-scale analysis method, multi-scale FEM is adapted for complex structure analysis and damage assessment [7][8] . The crack problem exists generally in each material and engineering structure.…”

The fatigue performance of steel truss integral joint is analyzed based on multi-scale FEM. Numerical results are verified with experimental ones. The fatigue performance of steel truss integral joint is analyzed using a sea-crossing suspension bridge as its background. The 1:2 scale model fatigue test is taken. After 2e6 time load loops, the stress situation of integral joint is stable and fatigue performance is satisfactory for requirements. The multi-scale FEM, whose main researching part adopts three-dimensional elements while the connecting component adopts the common beam element, can reduce the computational cost. The connection elements are used to connect the beam elements and threedimensional elements. The connection element has two joints, one of which has six degrees of freedom, three translation degrees of freedom and three rotational degrees of freedom, all degrees of freedom being coupled. The multi-scale FEM and the experimental one yield very close results The multi-scale FEM can provide an accurate simulation of the main research part and ensure the fatigue life forecast so as to simplify the calculation. This method is high efficient and feasible. The multi-scale FEM provides a new and reliable method for the fatigue performance of structure analysis.
