Numerical Simulation Studies of the Gravity Dam of Magnesia Concrete

The adding of magnesia expanding agent can effectively control the generation of concrete dam fissure, and can play the effect of simplifying the temperature control measure , shortening the time limit of the project , improving the economic benefits and so on . This study will use the Abaqus CAE software to analyze the gravity dam of magnesia concrete . Check the features of magnesia concrete by comparing the adding one and the no adding one , and summarize the results of the numerical value simulation and compile the software to provide the theoretical basis for the numerical value simulation of magnesia concrete dam.

Optimization Design for Automotive Interior Trimmings Based on Moldflow

Took the auxiliary fascia console lid of automotive interior trimmings for example, the preliminary plastic was designed by Pro/Engineer, then the Moldflow analysis on the plastic was performed. Those irrational factors of both injection technical parameters and structure of the plastic, which would occur in the injection molding process, were modified after analyzing simulation results. The rational plastic was obtained by repeating simulation and optimization, which indicated that the simulation-based optimization could improve the plastic quality and efficiency of injection molding. Meanwhile, the comparisons of mode locking force and molding time between microcellular foam and non-foam injection molding were also carried out, which showed the significance of numerical value simulation in injection molding processes.
