摘要
复杂光机部件图像采集地面仿真平台姿态扰动发生装置,是一种航空相机地面空中环境模拟装置。文中主要通过分析现有振动器,并结合其优点,设计出一种新型的仿真平台,用以实现在地面实验室中对航空相机进行空中飞行环境的模拟,从而进行探究影响航空相机拍照质量的影响因子,进而可以研制出解决该影响因子的云台,并可以测试云台的合理性。以及基于ADAMS虚拟样机并联机构运动学和动力学特性分析,为仿真平台整体结构的优化设计提供理论依据和主要参数。
The Attitude disturbance generator of the ground simulation platform for the image acquisition of the complex optical machine is an aerial camera ground air environment simulation device. Based on the analysis of the existing vibrator and its advantages, a new simulation platform is designed to simulate the aerial flight environment of aerial camera in the ground laboratory, which can be used to explore the influence factors which affect the photographing quality of aerial camera, and then develop a cloud platform to solve the impact factor. And the rationality of the PTZ can be tested. Based on the analysis of kinematics and dynamics characteristics of the parallel mechanism of ADAMS Virtual prototyping, the theoretical basis and main parameters are provided for the optimization design of the whole structure of the simulation platform.
