To research relationship of pressure drop with structure parameters of pleated stainless steel filter core of the hydraulic pipelines, a mathematic model between the structure parameters of filter core and pressure drop was constructed. The optimized struc- ture parameters of the filter core for XYZ-100 lubricant machine in the working state were searched, and the optimized structure parameters were simulated with FLUENT software. The calculated values were contrasted with the simulated values. It is shown that the opti- mized structure parameters calculated by the theoretical model are feasible.研究液压管路过滤系统褶型不锈钢滤芯的结构参数和压降之间的关系，建立滤芯结构参数和压降之间的数学模型。寻求XYZ-100稀油站所使用的过滤器滤芯的最优结构参数，并用CFD软件FLUENT对理论计算的最优结构参数进行数值模拟，将理论结果和模拟结果进行对比，结果表明：通过理论模型求得的最优结构参数是可行的。
