CAE Study on Dynamic Environments of the Space Optics Remote Sensor

空间光学遥感器所经受的主要力学环境是在运载、发射过程中的动力学环境,尤其是遥感器所经受的各种振动载荷,它直接关系到遥感器结构的稳定性,是影响遥感器在空间能否正常工作的关键因素。采用CAE技术对空间光学遥感器进行动态刚度及动力学载荷响应分析,旨在考查空间光学遥感器抗外界干扰能力和运载、发射、试验过程抗破坏能力。研究结果表明,空间光学遥感器具有较高的刚度,能够抑制动力学环境干扰,保持良好的动态特性,空间光学遥感器方案可行。

The main mechanics environments that the space optics remote sensor have to stand are dynamic environments in the course of transfer,launch,especially various kinds of vibration.It straightly influences the stability of optics remote sensor and is the main interfere factor of normally work in the space.The structure of the space optics remote sensor is analyzed on dynamic mechanical performance and dynamic response by means of CAE technology in order to investigate the abilities to avoid the external disturbance and damage during transfer,launch and dynamic experiment.The research result indicated that the space optics remote sensor has higher rigidity and can suppress the interferer of dynamic environment and hold good dynamic characteristic.The designed scheme of space optics remote sensor is feasible.
