Abstract: The purpose of this study is to evaluate the accuracy of a simulation model for the Rotary Friction Welding (RFW) process of AA6061 aluminum alloy. RFW, widely used in the aerospace and automotive industries, is known for producing strong welds with minimal heat-affected zones (HAZ). Using ABAQUS software, a numerical model was developed to simulate key aspects of the process, such as heat generation, material flow, and axial shortening. The simulation results were compared with experimental data and previous studies to validate the model’s accuracy. The comparison demonstrated the model’s ability to closely replicate reality welding conditions, making it a reliable tool for optimizing welding parameters and improving the RFW process for AA6061.

Abstract: ABAQUS is a powerful software for simulating nonlinear material models with complex thermo-mechanical behavior. Its robust capabilities make it particularly suitable for simulating the Rotary Friction Welding (RFW) process. In this study, ABAQUS was utilized to simulate the RFW process of AA6061 aluminum alloy, focusing on key aspects such as weld morphology, temperature distribution, and axial shortening. The simulation results were analyzed and validated against theoretical foundations of the RFW process and previous research, demonstrating the model's high reliability. These findings highlight the potential for further development of the simulation model for various applications, aimed at enhancing the efficiency and effectiveness of RFW in industrial applications.

Abstract: The adjustment test of steering column is an important parameter for automobiles safety, but the unified standard and test method are not yet formed. Build parameterized model of steering column internal and external spline shafts, and analysis the contact stress changes in the movement process using Abaqus/standard. The movement speed of 5 mm/s in the x, y direction as example, and stress distribution of regulating movement are obtained. Experimental result shows that the maximum overall stress grows with the adjusting movement speed growth, and its in conformity with actual parts failure.

Abstract: The quality of high speed machining is directly related to dynamic characteristics of spindle-toolholder interface. The paper established normal and tangential interactions of BT spindle-toolholder interface based on finite element contact theory, and analysed free modal in Abaqus/Standard. Then the result was compared with the experimental modal analysis. It shows that the finite element model is effective and could be applied in the future dynamic study of high-speed spindle system.

Abstract: This article took the PC main board as a research object and simulated how to optimize the position of the desktop main board pads. The static stress analysis was executed using ABAQ -US/Standard. The objective was to reduce the local deformation of computer main board occurs when the connector was inserted and extracted during the assembly process, preventing the chips and capacitances on the main board from becoming invalid. The simulation results showed that the FEA method with Abaqus can be used to predict the main board performance and structure optimization.

Abstract: As a universal finite element method commercial software, ABAQUS has been widely used in scientific research and engineering applications. However, convergence difficulties are familiar issues while carrying out damage and fracture analysis. Several methods, which are helpful to avoid these convergence problems, are presented in this paper. Baseline simulations about damage initiation and propagation in composites indicate that a larger value of viscous regularization causes the peak of the reaction force to be higher. A smaller viscosity parameter is better than bigger one. Other advanced techniques, include using automatic stabilization and customized general solution controls, are adoptable to improve convergence in ABAQUS/Standard analysis. The results of the paper are expected to provide guidance for the new user of ABAQUS.
