Abstract: Y-Type rolling mill with three roller is a new kind of wire mill.The three-dimensional models of rolling are established by Pro/E. Based on the finite element analysis software ANSYS/LS-DYNA, the rolling process of wire by Y-type rollers is simulated. The rolling piece movement is analysed. Stress and strain of Y-type roller are also analysed.

Abstract: Simulation model of Hydraulic steering system with flow amplification, which is widely used in traffic engineering machinery, is established in AMESim8.0.0 environment. Through the structure analysis of the system's three compositions, which are priority valve, steering gear and steering cylinder, are modeled by using the library of HCD. According to parameters of the actual structure of the system, the simulation parameters are set to every component of the model. Under the circumstances of step signal with different angle, rotation, and load force, the simulation results of the model turn out to be in accordance with the characteristic of the real system, which indicates feasibility and reliability of the model to specific performance analysis and optimization design.

Abstract: The traditional color matching method for textile dyeing by experiences cannot meet the needs of modern production for color matching in textile dyeing. In order to solve this problem, a mathematical model for the three stimulus values CMY and the dye weight concentrations has been established by collecting and analyzing the actual data from a factory. We analyze this model by polynomial least square approximation and polynomial regression, and then we solve the dye concentrations with the Newton iteration method. Verification results show that the error between the experimental values and the actual values is very small. So this model has higher accuracy, and it can be used in actual productions.

Abstract: Fruit sorting machine of weighing type was used most widely in fruit grading market, which study on its structure adopting traditional 2D plan method is too abstract to modify hardly. Therefore a new weighing type of fruit sorting machine was designed using Solid Works, through which the design is for stents, tray institutions, transmission system and sprocket shaft of the sorting machine was realized, and 3D model for the motor reducer and bearing socket was built so that the overall assembly for the fruit sorting machine was achieved. Afterwards,3D modeling, virtual assembly as well as compute clash and primary FEM analysis were carried out for parts of machine. The application results show that Solid works is beneficial to new agricultural machinery design, which shall shorten the development cycle and improve the design quality.

Abstract: With the development of the hardware in Chinese iron industry, scheduling technology is becoming key obstacles that hold back the further development in iron enterprise. And the scheduling theory about the process of steelmaking-continuous casting can’t fit the actual production. To improve this situation, we manage to develop the system the combine the editable Gantt chart and optimization models. On one hand, this system can use Gantt chart to show dispatcher real-time schedule and allow dispatcher reschedule on Gantt chart. On the other hand, the system can detect the change dispatcher made and use the optimization model to complete the whole schedule. In a word, this system takes advantage of the scheduling ability of dispatcher and the high speed calculation of computer to reschedule efficiently.

Abstract: As a substantial power loss, the high speed automotive hydraulic power steering outputs normally exceeds the system actual demands, which is one of the practical difficulties of that kind of power steering. A new type of variable displacement of double-action vane pump based on the study of a patent is described in this issue, which could be applied in the auto steering pump. Considering of the severe energy cost in existing hydraulic power steering system, the recommended pump could compensate the rate. Based on the pump principle, the interior structure design of the pump could be improved to achieve saving energy. A rational pump structure is designed for lower energy lost according to the research on the characteristics of the variable mechanism under various speed, working conditions of the improved vane pump structure and the energy saving theory. Compared to the traditional double-action vane pump, the new vane could not only keep the advantages such as balance of radial suffer force for rotor but also change the displacement automatically according to different speeds. The transformation regulation applying on the variable mechanism floating block under different rotating speeds is analyzed derived according to the engineering dynamics principles and the dynamics model of variable framework is set up in the same way. Some MATLAB simulations are utilized to show a theoretical feasibility proof of the project.
