摘　　要：基于新型控制阀配气阀芯的配气原理,建立了配气阀芯主进、排气孔通流截面积计算公式。对马达原有配气阀芯的配气量进行理论计算,根据计算结果,对现有配气阀芯的结构进行优化。利用气动马达专用测试平台测试马达在改进前后的配气阀芯时输出的扭矩和功率。探讨了传统配气阀芯与优化后新型配气阀芯对气动马达动力性能的影响。结果表明,对配气阀芯结构上的优化是合理的。Based on the valve principles of the valve spool of the new gas control valve ,the cross-sectional area cal- culation formulas of the main gas valve inlet and vent through-flow is established. The special test platform of the air motor can be used to test the torque and power of the output of the motor before and after the improvements the valve spool. The effects about the dynamic performance of the new and traditional pneumatic motor gas valve spool was ex- plored.The results show that the optimization of gas distribution valve structure is reasonable.
