摘要
建立了带有预定时标齿轮四杆机构连杆轨迹的数学模型 ;导出了计算机构实际尺寸和安装位置尺寸的数学公式 ;提出了通过对连架杆摆角算子进行快速Fourier变换 (简称FFT) ,建立其数值图谱库 ,经过模糊识别进行连杆轨迹尺度综合的方法 ;
Mathematical model for track of connecting rod in geared four-bar linkage with predetermined clock is established, and the mathematic equations for calculating actual dimensions of mechanism and positional dimensions of installation are derived. By means of conducting Fast Fourier Transformation(FFT in short) on side link swinging angle operator to build its numerical atlas library and through fuzzy recognition a method is put forward for carrying out dimension synthesis of track of connecting rod. Finally, a calculational example of synthesizing the track dimension of connecting rod in geared four-bar linkage is given out.
