从轴承的接触理论和提出的振动模型所得到的计算方法,可以计算镜筒旋转轴支承的动、静力承载能力,支承刚度,镜筒的径向和扭转振动频率。把这些参数都用轴承的结构因素——滚子半径、轴承节径、密合因素、充填系数、接触角等来表示。由此可对光学跟踪仪器在总体设计时考虑镜筒振动频率的情况下,更合理的选定镜筒旋转铀的支承型式。并给出ATT的计算实例。
Based on the contact theory of the bearing and the calculation method of the proposed vibration model, the dynamic and static bearing capacity, the bearing stiffness, the radial and torsional vibration frequency of the lens barrel can be calculated. These parameters are used bearing structural factors - roller radius, bearing section diameter, close fit factor, filling factor, contact angle, etc. to represent. This makes it possible for the optical tracking instrument to take into account the tube vibration frequency in the overall design case, and to select a more reasonable mode of support for the rotation of the lens barrel. And give the calculation example of ATT.
