摘　　要：本文根据三维非稳态传热理论,考虑强制对流散热,分别建立了风冷式和水冷式振动台线圈的传热模型,得到线圈散热量的计算公式。分析了进风路径、动圈运动和腔体内空气回流对风冷式振动台冷却的影响,并给出了相应的解决策略。同时,通过仿真推导出了线圈的沿程阻力系数和弯管阻力系数。在不影响磁场强度的前提下,对水冷式振动台线圈导线的过水截面积进行了优化,提升了水冷效率。本研究可为振动台的冷却设计提供参考。In this paper,considering the three-dimensional unsteady heat transfer theory and the forced convection heat dissipation,the heat transfer models of the moving coils of air-cooled and water-cooled shaking table are established respectively,and the calculation formula of heat dissipation of the moving coil is obtained.The influences of air inlet path,the periodic motion of moving coil and air concussion in the cavity on the cooling of air-cooled shaking table are analyzed through simulation,and the corresponding solutions are given.The frictional drag coefficient and the curve resistance coefficient of the moving coil are also derived through simulation.Without affecting the magnetic field strength,the cross section area of the coil conductor of water-cooled shaking table is optimized,which improves the water-cooling efficiency.The study of the paper provides a reference for the cooling design of the shaking table.
