round angle 【數學】(360度)周角。

round arm

A concept of step - by - step round angle surface for transition and its mathematic modeling was put forward first time . different fiber placement patterns ( 0 , 90and 45 ply ) and their simulation module were designed . a simulation system for fp - - - - - - simjoint system for satellite triangle conjunction was composted , which include mandrel modeling , fiber placement trace in mandrel simulation and robot ' s kinematics simulation 詳盡描述了構架式衛星接頭的幾何建模過程,針對所研究對象的特點,提出了用于變截面曲面之間過渡的漸進圓角過渡曲面的概念,并建立了相應的數學模型;針對構架式衛星接頭設計了90 、 0和45等不同角度對應的纖維路徑和鋪絲線型仿真模塊。

Based on this model , the effects of geometric and structural parameters , such as injection pressure , rear pressure , length - diameter ratio , inlet round angle - radius ratio and non - axis symmetry of nozzle , on the distribution of the cavitation inside the nozzle are analyzed 基于這一模型進一步分析了噴射壓力、背壓和噴孔長徑比、噴孔入口圓角比、非軸對稱噴孔等幾何結構參數對噴孔內空穴分布的影響。

Simulation results show that better atomization can be realized by enhancing the cavitation intensity via increasing the injection pressure difference or decreasing the nozzle inlet round angle - radius ratio 通過模擬計算可知,提高噴射壓差和減小噴孔入口圓角半徑都可以提高空穴強度,同時也發現提高噴孔長徑比可以使空穴在噴孔出口截面上分布更為均勻。
