Hydraulic Circuits

For the limitations of the existing hydraulic test bench for experimenting with multi-species of hydraulic components, the additional cartridge valve circuit and multi-way directional valve circuit were designed. The AMESim simulation models of the hydraulic test benchs basic hydraulic circuits were established and simulated. Then the simulation results were compared with the experimental data to get some principles of simulation modeling and optimize the models. These principles were used to simulate the additional hydraulic circuits. Through analysis of the simulation results, theory supports were provided to the optimal design of hydraulic test bench. In this way, the existing hydraulic test bench can be fully used and the suitable components were selected, reducing the waste of resources. Besides, the simulation models can be used as part of the virtual hydraulic teaching.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
