Optimal design on toroidal roller bearing is realized, in which inner geometry parameters are considered as design variables, while the static load rating, fatigue life, wear life and high stress at roller ends are chosen as objectives. 首先对圆弧滚子轴承进行优化设计,以轴承内部几何尺寸作为设计变量,提出以静承载能力、疲劳寿命、磨损寿命以及修形滚子边缘高接触应力的缓解这四项作为优化设计的目标。
Inner geometry parameters are deemed as design variables. The four objectives are static load rating, fatigue life, wear life and maximum stress in the rib respectively. 以轴承内部几何尺寸作为设计变量,提出将静承载能力、疲劳寿命、磨损寿命以及挡边中最大应力值这四项作为优化设计的目标。
A non-contact measuring instrument based on image detection technology is developed to measure the fiber ferrule inner hole geometry parameter. 为了测量光纤插针内孔的几何参数,研制了一种基于图像检测技术的非接触式光纤插针内孔几何参数测量系统。
The advantages of the CRT with optimized inner surface geometry include less virtual image distortion and higher strength against air pressure because of larger radius of the inner surface curvature. 采用此设计方法制作彩色显像管,既能得到失真较小的显示图像,又能使显示屏内表面曲率半径较大,提高显示屏抵抗大气压力的能力。
