摘要

为深入研究电磁斥力机构的多物理场耦合及其在产品设计中的影响，采用理论建模和仿真实验的方式，以温度场为媒介对典型电磁斥力机构运动参数进行多物理场耦合建模，统筹分析电场、磁场、温度场、应力场等多物理场的耦合效应。首先，通过实验验证仿真模型的准确性；其次，对比分析顺序耦合与直接耦合之间的差异，归纳出单次动作时多场耦合对电磁斥力机构运动参数的影响；最后，通过多场耦合的仿真研究分析不同环境、不同工况下电磁斥力机构各运动参数的变化情况。仿真结果表明：温度场对单次动作的影响可以忽略；温度场对复杂工况下斥力峰值、速度峰值等机构运动参数的影响超过5%；随着温度升高，机构安全系数降幅可达18%，温度超限对机构的寿命影响较大。该文研究对复杂工况下的机构运动参数及其寿命研究的准确可靠性有重要意义。

Abstract

Theoretical modeling and simulation experiments are used to deeply research the multi-physical field coupling of electromagnetic repulsion mechanism（ERM） and its influence in product designs. The motion parameters of typical ERM are modeled by multi-field coupling which takes the temperature field as the medium

moreover

the multi-field coupling effects of electric field

magnetic field

temperature field and stress field are overall analyzed. Firstly

the accuracy of the simulation model is verified by experiments. Secondly

the differences between sequential coupling and direct coupling are compared and analyzed

the influences of multi-field coupling on the motion parameters of ERM during single motion are summarized. Finally

the variations of motion parameters of ERM in different environments and working conditions are analyzed through the simulation of multi-field coupling. The simulation results show that the influence of temperature field can be ignored during single motion. The influences of temperature field on the motion parameters such as peak value of repulsion and peak value of velocity are more than 5% under complex conditions. As the temperature rises

the safety factor of the mechanism decreases by 18%

and the overrun of temperature has great impact on the life of the mechanism. The research in this paper is of great significance to the accuracy and reliability of the research on the motion parameters and the life of the mechanism under complex working conditions.
