4WRKE25E350L-33/6EG24K31/A1D3M

4WRKE25E350L-33/6EG24K31/A1D3M初步设计时可以按双喷嘴挡板力反馈两级电液伺服阀进行设计，由于输出性能指标与前面所设计力反馈伺服阀性能指标一样，因此滑阀和双喷嘴挡板阀参数可按力反馈伺服阀设计，取阀芯直径d=5mm，阀芯行程xvm=0.5mm，滑阀面积梯度W=5.14mm，双喷嘴挡板阀喷嘴孔径DN=0.48mm，固定节流孔直径D0=0.21mm，喷嘴挡板零位间隙xf0=30μm。

下面设计计算主要用来确力矩马达、控制器、传感器等结构参数上。

1.力矩马达设计计算

4WRKE25E350L-33/6EG24K31/A1D3M根据电液伺服阀的频宽要求确定力矩马达的固有频率 根据伺服阀的频宽要求，由式（5-82）可求出开环增益

Kdvf=0.707ωb=0.707× 2π× 225rad/s=999.5rad/s

由式（5-61）可确定力矩马达的固有频率

ωmf≥4Kdvf=4999.5rad/s=3998rad/s

为留有一定裕度，这里取最小值的1.2倍，因此ωmf=4800rad/s。

电反馈电液伺服阀开环增益Kdvf大于力反馈电液伺服阀开环增益Kvf，这里取

Kvf=0.5Kdvf=500rad/s

4WRKE25E350L-33/6EG24K31/A1D3M计算反馈杆刚度 参考已有电液伺服阀结构参数，选取表5-1中结构参数。由式（5-18）得力矩马达综合刚度
