| 摘 要： | 在结构设计解决周视光电观瞄设备的动态密封问题后，动密封所带来的摩擦力矩就成为周视光电稳定的重要制约因素。通过对3种典型应用动密封原理的周视光电观瞄设备分析研究，着重分析了动密封的摩擦力矩对结构、稳瞄精度的影响，并结合实际工程应用给出3种动密封形式所对应的摩擦力矩分析和估算方法，提供给稳瞄和结构设计人员，以期对后续稳瞄系统设计有所帮助。最后在同一周视转台上，对3种动密封进行了试验验证并进行分析计算，得出磁流体是解决周视光电设备动密封较好形式的结论。

| Abstract: | In order to solve the dynamic sealing of the panoramic electro-optical aiming device, through analysis of three typical kinds sealing principle of the panoramic electro-optical aiming device, the influence of friction torque of dynamic sealing on structure and accuracy of stabilized platform was analyzed. Combining with application of engineering practice, three kinds of sealing corresponding to the friction torque analysis and estimation methods were given, in order to help the follow-stabilized platform system design. Experiments of three kinds of dynamic sealing were analyzed and calculated respectively. Results indicate that magnetic fluid is the better way to solve the problem of dynamic sealing of electro-optical devices. |
