查询词典 fan window

According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

选择矩形窗、三角窗、hanning窗和blackman窗生成4种11步移相算法，对振动误差和相移误差的分析验证了旁瓣小的hanning窗和blackman窗生成的算法对误差的灵敏度要小；再选择hanning窗生成了移相间距为π/2的5，11，15，39，51，76和101步7种移相算法，仿真验证了步数越多主瓣越小，对振动抑制能力越好，但需要更高的微位移器移动精度来获得有效的干涉条纹。

This blowing fan has a hub connected to the rotating shaft of a motor and a number of blades mounted on the outside surface of the hub at fixed intervals to flow air in the centrifugal direction of the fan. Although this fan is produced in a shape of axial fan or diagonal fan by integrally forming the separate turbo blade on the tip or trailing edge of the rotor blade, the blowing noise can be reduced in addition to the increase in the entire wind quantity of the fan by embodying the optimum set angle of the turbo blade.

In some conventional fan revolution speed control methods, variable control of the number of revolutions of a cooling fan is performed by a process comprising steps of detecting an actual temperature of cooling target fluid, ie fluid to be cooled by the cooling fan, such as hydraulic oil and circulating radiator cooling water for cooling an engine (such cooling water is hereinafter referred to as coolant), determining a target fan revolution speed by a system of a proportional integral control unit based on the difference between the actual temperature detected and a target temperature, and changing the fan revolution speed based on the target fan revolution speed so as to bring the actual temperature of the cooling target fluid down to the target temperature.

在一些传统风扇转速控制方法，控制变量的数目革命的一个冷却风扇，是由一个过程组成的步骤检测到一个实际温度冷却目标流体，即流体被冷却，由冷却风扇，如液压石油和散热器循环冷却水用于冷却发动机（如冷却水是以下简称为制冷剂），确定一个目标风扇转速由一个系统的比例积分控制单元基础上的差异，实际温度检测和目标温度，并改变风扇转速的基础上，针对风扇转速，使实际温度的冷却液指标下降到目标温度。
