摘要：在無線能量傳輸系統(tǒng)中，兩個線圈之間的互感系數(shù)是影響傳輸效率的關(guān)鍵性因素之一。當兩個線圈之間的相對空間位置變化時，對不同空間位置下兩個線圈之間互感系數(shù)的計算就顯得尤為重要。針對多層平面螺旋圓線圈，基于聶以曼公式提出了一種改進的互感系數(shù)的理論計算方法。計算出兩個線圈之間出現(xiàn)軸心偏移、橫向偏移以及角度偏移情況下的互感系數(shù)，并與有限元仿真和實驗測量結(jié)果進行對比，驗證了所提出理論計算方法的正確性。該計算方法可以計算任意空間位置下多層平面螺旋線圈之間的互感系數(shù)，而且適用于螺線管線圈和單層平面螺旋線圈，為線圈的設(shè)計和優(yōu)化提供了理論依據(jù)。

Abstract: In the wireless power transfer system, the mutual inductance between two coils is one of the key factors affecting transfer efficiency. The calculation of the mutual inductance between two coils is especially important when the relative spatial location varies. In this paper, an improved calculation method based on Neumann formula for the mutual inductance calculation between multi-layer planar spiral coils is presented. The mutual inductance coefficients between two coils under axial offset, lateral displacement and angular misalignment are calculated and compared with the results of finite element simulation and experimental measurement, and the correctness of the proposed theoretical calculation method is verified. This calculation method can be used to calculate the mutual inductance between the multi-layer planar spiral coils in arbitrary space position and applied to helical coil and single-layer planar spiral coil, which provides a theoretical basis for the design and optimization of coils.

Key words: wireless power transfer; mutual inductance; spatial location; multilayer planar spiral coil

A experiment method is provided for the selection of capillary in different conditions. The system takes the single-chip microcomputer as the controller.By controlling the micro-air pump, constant pressure difference is provided for both ends of the capillary tube. Pressure sensors are used for pressure detection at both ends of the capillary tube.

Luoyang Quality and Technical Supervision and Testing Center, Luoyang 471000, China Abstract: Inertial navigation system is an indispensable part of precision guided weapons. In a tactical or miniaturized product, individual temperature error compensation and other measures are usually used to suppress the influence of ambient temperature. Therefore, it is necessary in the production lines to calibrate the temperature measuring components of fiber optic gyroscope inertial navigation system and keep the error with the reference temperature source within a certain range through the adjustment. Based on the analysis of temperature measuring circuit, a debugging method is put forward for the rapid adjustment of the temperature measuring circuit, which adopts threetemperature-point test method to measure temperatures, performs the linear fitting of the test data, and adjusts the debug resistance combined with the influence of the debugging resistance on the slope and intercept of the fitted curve. The test results show that the method is feasible.
