The Stability

The tool falling and vibration faults often occur in the process of tool changing, In order to improve the stability of the tools on automatic tool changer, a new structure of the manipulator is presented. The new manipulator contains two-point locking instead of the original one-point locking, and the tools can be clamped more tightly. When the old manipulator is slotting the tool, the forces are analyzed, and the working load and parameters is determined by calculating and analyzing the output curve of manipulator. The three-dimensional model is built in ADMS, and the validity of the new designed manipulator is verified by the simulation in a limit state. The simulation result shows that the new manipulator can increase the ability of tool clamping effectively.

Simulation Results

Two kinds of three-dimensional model are built to simulate the gas entrainment process through a small break in the horizontal coolant pipe at the bottom of the stratified flow. The results were compared with the two-dimensional simulation results and the experimental data. In terms of the two-phase distribution, the simulation results agree well with the experimental data and show much superiority compared with the two-dimensional model. The results verify the reliability of model building, condition setting and calculating method qualitatively and quantitatively. In general, after gas entrainment, the average velocity over cross section increases obviously, but the mass flow rate decreases contrarily. This is because that void fraction meanwhile reduces the fluid density. In addition, it is found that the larger the void fraction of vapor is, the higher the average discharge velocity of the fracture cross-section fluid is. Besides, with the larger internal and external pressure difference, the gas volume fraction and the flow velocity in the break increase, resulting in the mass flow rate increasing along with them. However, since the critical height increases as well, the total loss amount of liquid in the stable effluent stage decreases, and the time before entrainment becomes shorter.

Lapping Machine

The V-groove angle of the machine is considered as one of important factors affecting the processing and the ball’s precision. To study its effect, the three-dimensional model of RDP lapping machine is built and a series of simulations at different V-groove angles are carried out, using the software ADAMS based on the RDP principle. The influence of three parameters including spin angle, spin angular velocity and revolution angular velocity are discussed by observing and analyzing the simulation results. It is concluded that some optimized V-groove angles can improve the sphericity of ball; some ones can induce the balls to move back and roll during some periods of the processing.
