一种航空遥感器动力学环境试验工装的设计与分析

Design and Analysis of a Kind of the Aerial Remote Sensor’s Dynamics Environment Test Fixture

航空遥感器振动试验是航空遥感器研制过程中不可或缺的过程之一,而振动工装的设计则是顺利完成振动试验的关键环节。振动工装性能直接影响到振动试验的真实程度和可靠程度。本文设计了某型航空遥感器振动工装,并通过工程分析及振动试验对其特性进行分析及试验验证。振动试验结果表明,振动工装振动传递率为1.12,可真实地传递振动台施加给遥感器的振动及冲击,其固有频率及振动传递率满足设计及使用要求。

Aerial remote sensor vibration test is one of the indispensable processes in the aerial remote sensor manufacturing,and designing the vibration test Fixture is the key node for completing the vibration test successfully.Vibration fixture’s performance directly affects the reliability.A certain type of aerial remote sensor vibration fixture is designed in this paper.The CAD analysis and vibration test are introduced.The vibration test results shows that the vibration transmission rate of the vibration fixture is 1.12,which can truly carry vibrations vibration and impact to the remote sensor.
