在适当简化试验系统之后,通过绘制交流液压系统的分段集中参数功率键合图,完成了推导液压系统的整个状态方程。最后再利用对封装系统的管道长度还有频率和管道内径等这些参数值的变动,找出参数对本课题中交流液压系统管道相位还有传输效率等等的影响情况。本课题对这些不一样形状管道的具体特征,通过Pro/E软件来完成系统液压管道内部具体振动的区域建模,再通过CFX模块来完成域物理条件定义和最后的结果处理,并且最后得出流体流经每种不一样管道的具体速度矢量分布图还有对应的不同压力分布图,探究了流体在各种不一样的频率下流经每一种形状管道时的压力还有速度的不同流场特性。
After properly simplifying the test system, the entire state equation of the hydraulic system is derived by plotting the power bond graph of the sectioned centralized parameters of the AC hydraulic system. At last, the influence of the parameters on the pipeline phase and the transmission efficiency of the AC hydraulic system in the subject is also found out by using the changes of the pipeline length and the pipe diameter of the package system. The subject of these different shape of the pipe for the specific characteristics of the system through the Pro / E software to complete the hydraulic system within the specific vibration of the regional modeling, and then through the CFX module to complete domain definition of the physical conditions and the final results, and finally draw The fluid flow through each of the different pipe-specific velocity vector maps and the corresponding pressure distribution maps explored the different pressures and velocities of the fluid flowing through each of the shaped pipes at various frequencies characteristic.
