摘要
光电测量吊舱工作于高速、高空、高风载、高振动条件下,且受制于其气动特性,故体积无法太大,因此吊舱舱体内部的结构部件需要完全适应上述苛刻条件,且做到结构紧凑。首先分析了吊舱头部局促空间的设计要求。该吊舱头部最大外形尺寸为390mm×600mm。但该空间内包含三对轴承、四个框架、两套可见光电视系统、一套光路快速控制系统及相关的电路、控制陀螺等元器件。因此在如此狭小的空间内合理配置如此多的系统必须进行相应的结构优化设计与分析。根据充分的论证分析提出了一系列设计要求。根据设计要求对吊舱头部关键部件进行了参数计算、型号选择、结构设计。应用MSCPATRAN软件对基座和横滚框架进行了有限元模态和静力学分析,验证了设计的合理性。
The optic-electronic measure pod works under the condition that high speed, high altitude, high weed carry and many librations. And the bulk of the pod is not too big which is enslaved to the air characteristic. So the inner structure of the pod should entirety fit that rigor condition. And the structure should be gathering together. First of all, the pod head design was analyzed, which was the most important requirement-cramped space. The pod head maximum size was 390 mm×600 mm. But the space contained three pairs of bearings, four frame, two sets of visible light TV system, a set of optical path of rapid control system and related control circuit, the gyro etc. Therefore, to carry on the corresponding structure optimization design and analysis for the system is reasonable in such narrow space configuration. According to the full demonstration analysis, a series of design requirements was put forward . Based on the design request, the parameters of important parts of the pod head were calculated with model chose and structure design. The mode and statics of radix seat and the across rolling frame were analyzed based on the MSCPATRAN software which can validate the structure design rationality.
