摘要

摘要:
为寻求提高批量电液伺服阀分辨率一致性的制造工艺方法，针对滑阀副径向尺寸公差范围内参数摄动作用下卡紧力大小的不确定性，建立了径向卡紧力数学模型，获得了径向尺寸参数摄动下的滑阀副径向卡紧力分布特性。建立了工艺参数与径向卡紧力分布特征参数之间映射关系的响应面代理模型，并据此开展了滑阀副径向卡紧力分布特征参数对工艺参数的全局灵敏度分析。结果表明：径向卡紧力服从Weibull分布，改变阀芯圆柱度相比改变径向间隙对滑阀副径向卡紧力影响较小。相比减小径向间隙变动范围，降低径向间隙下限值对提高径向卡紧力一致性更加有效。而相比降低径向间隙下限值，减小径向间隙变动范围对从整体上减小径向卡紧力更为显著。

Abstract:
In order to find a manufacturing process method for improving the resolution consistency of batch electro-hydraulic servo valves, a radial clamping force distribution model was established to describe the uncertainty of clamping force under parameter perturbation within the radial dimension tolerance range. And the distribution characteristics of the radial clamping force of spool valve couples were obtained. Furthermore, a response surface surrogate model of the mapping relationship between process parameters and radial clamping force distribution characteristic parameters was established. On this basis, global sensitivity analysis of radial clamping force distribution characteristic parameters to process parameters was carried out. The results showed that with the perturbation of radial dimension parameter, the radial clamping force was subject to Weibull distribution. Compared with the radial clearance, spool’s cylindricity had less effect for radial clamping force. Compared with reducing the variation range of the radial clearance, reducing lower limit of radial clearance was more effective to improve the consistency of radial clamping force. Compared with reducing the lower limit of radial clearance, reducing the variation range of radial clearance was more significant to reduce radial clamping force as a whole.
