摘要：在无线能量传输系统中，两个线圈之间的互感系数是影响传输效率的关键性因素之一。当两个线圈之间的相对空间位置变化时，对不同空间位置下两个线圈之间互感系数的计算就显得尤为重要。针对多层平面螺旋圆线圈，基于聂以曼公式提出了一种改进的互感系数的理论计算方法。计算出两个线圈之间出现轴心偏移、横向偏移以及角度偏移情况下的互感系数，并与有限元仿真和实验测量结果进行对比，验证了所提出理论计算方法的正确性。该计算方法可以计算任意空间位置下多层平面螺旋线圈之间的互感系数，而且适用于螺线管线圈和单层平面螺旋线圈，为线圈的设计和优化提供了理论依据。

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

Abstract: Capillary is a kind of widely used throttling device. Because of the existence of liquid laminar and non-laminar flow in capillary tube, the flow calculation is more complicated. In view of the fluid characteristics of the liquid through the capillary, a capillary flow differential pressure control system is designed, which explores the characteristics of capillary differential pressure flow. 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.

摘要：惯导系统是精确制导武器中不可或缺的重要组成部分。在战术级或小型化产品上通常要对每个产品进行单独温度误差补偿等措施以抑制环境温度的影响。因此在生产线上，需要对光纤陀螺惯导系统的测温部件进行专门的标定，通过调整环节使其与基准温度源的误差保持在一定的要求范围内。通过对测温电路的分析，提出来一种测温电路调试方法，对三温度点测试法得到的测试数据进行线性拟合，结合调试电阻对拟合曲线的斜率和截距的影响关系调整调试电阻的大小，即可快速完成测温电路的调试。实际测试证明该方法是可行的。

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.

Abstract: At present, most of test control systems are controlled separately by subsystems, which leads to the low degree of automation and information. With the development of large thrust liquid rocket engineering and the upgrading of hardware equipments, the reliability of the test systems must reach a higher level, especially for the applications with less operators in multi-links, multistates and multi-parameters envirment. A dual-machine parallel redundancy control system based on redundant s7-417h PLC for liquid rocket tests is designed in this paper.Some ways to improve system reliability including hardware, peripheral protection circuits, anti-interference and error prevention software, redundant Ethernet are explained. And also, the hardware reliability indexes of the key system equipment are quantified.
