摘　　要：针对飞机起落架深孔型腔加工时切削应力大、刀具损耗严重、生产周期长的问题,提出一种深孔型腔电解加工技术。通过制定的深孔型腔电解加工方案设计了加工流道结构,同时利用Comsol软件对深孔型腔电解加工过程中的电场、温度场进行数值模拟仿真,得到加工间隙内电场、温度场工艺参数的分布变化规律。最后,通过试验实现了起落架深孔型腔结构的高质量制造,获得制件实测点和理论点的平均误差为0.148 mm,型腔表面粗糙度最大值为Ra1.81μm。A electrochemical machining technology(ECM) aimed at deep hole cavity was proposed to address the problems of high cutting stress,severe tool wear and long production cycle for aircraft landing gear.The machining channel structure was designed through the developed deep hole cavity ECM scheme,and the electric field and temperature field during the deep hole cavity ECM process were numerically simulated using Comsol software to obtain the distribution and variation of process parameters of the two fields within the machining gap.Finally,high-quality manufacturing of the landing gear deep hole cavity structure was achieved through experiments,with an average error of0.148 mm between the measured and theoretical points of the workpiece,and a maximum surface roughness of Ra1.81 μm.
