在仿真研究中,路面激励取为白噪声、正弦波和锯齿波,悬架类型采用被动悬架、 pid控制半主动悬架、神经网络控制半主动悬架三种。 - Base on the model founded , this paper assessed the ride performance by analyzed the root mean square value of power spectral density of acceleration of z - axis and round y - axis rotation acceleration at the driver ’ s seat . the root mean square value of suspension working spaces and dynamic tyre loads were also analyzed . base on the assessing system of vehicle ride performance , the root mean square
根据模型建立的实际情况,对车辆标准载荷情况下的平顺性指标进行了计算,对人体感受到的振动采用了垂直方向和绕横轴转动方向的加权振级来评价,计算了车辆悬架系统的动挠度均方根值和各车轮相对动载荷均方根值的情况,全面的评价了车型的平顺性。 - The research result demonstrates that along with the increment of reynolds number , the root mean square value of outer fluctuating magnitude of the external diameter in fall frequency band increases , the root mean square value of fluctuating magnitude of the external diameter in high frequency band decreses , demonstrating that the fluctuation of flexible pipe wall changes fluctuation don field of original rigid pipe , large - size eddy motion increases and small - size eddy motion decreases , this reduces energy loss and increases friction reduction effectiveness
研究结果表明:随着雷诺数的增加,全频带的外径脉动的均方根值加大,但高频带外径脉动的均方根值减小,说明柔性管管壁脉动确实改变了原刚性管的脉动流场,大尺度涡的运动加剧,低尺度涡运动减弱,从而使得能量损失减少,减阻效果增大。 - ( 2 ) data - processing module , its functions is using dsp processor to designdigital filter for the receiving signals , work out the root mean square values and phaseangle , then the phase compensation technique is applied to modify the signals , at lastexport the combining frame data . to data - output module . ( 3 ) data - output module , its functions is transmitting combining frame data toethernet controller , then send the data to the protective device
( 2 )数据处理模块利用dsp处理器对接收到的数据信号进行数字滤波设计,求出相应的均方根值及相位角,并对信号进行相位补偿,最后将数据组帧后传给数据输出模块; ( 3 )数据输出模块将组帧后的数据传送到以太网控制器,继而发送给二次保护测控设备。
