Efforts must be made to accelerate the establishment of a radio management technology system in beijing , to improve the overall capability of spectrum management , radio signal monitoring , interference analysis and radio equipment testing 加快构筑北京市无线电管理技术支撑体系,全面提高频谱管理、无线电信号监测、干扰分析和无线电设备检测能力。
An discriminantt rule to transfer interference analysis from three dimensional space to two dimensional space is presented with consideration of shape and volume of two booms in the case . and practical analysis is applied on simplified model of two booms by the discriminant rule . the method presented discriminate simply , calculate quickly and has importantly applied value 在考虑双臂形状与尺寸的情况下,提出了一种将干涉分析由三维空间转化为二维平面的判别准则,并将干涉判别准则在双臂的简化模型上进行了实际的分析,该方法判别简单、计算速度快,具有重要的实用价值。
On the platform of the 3ds max and max script , the 3d modeling , motion simulation and interference analysis for the new type of parallel machine tool are developed in the virtual environment . based on it , the reliable foundation is provided for checking the dynamic and static interference problems of machine tool structure design , verifying the rationality of path planning , and appraising the technological process and the rationality of the processing parameters of parts 基于3dsmax和maxscript脚本语言开发平台,在虚拟环境下进行了并联机床的实体建模、运动仿真和干涉分析,为检查机床结构设计中的动静态干涉问题、验证轨迹规划的合理性、实现对零件可加工性及加工参数的合理性评价提供了可靠的依据。
