基于可靠性优化的机载显控设备结构设计

摘要

文中提出了基于可靠性的优化设计方法,并将该方法应用到机载显控设备的结构设计过程中。通过热、振动应力分析发现设备的薄弱环节,并针对薄弱环节对该设备的设计进行了优化,从而提高设备的抗振性能和散热能力。在上述分析与优化基础上,进行该设备的可靠性分析与优化,确保设备的可靠性指标。最后对设备的环境适应性与可靠性指标进行了试验验证,表明了该优化设计方法的有效性。%Optimization design method based on reliability and its application to structure design of cockpit display and control device are presented in this paper.The capability improvement of anti-vibration and heat transformation can be achieved by optimization design of unsubstantial parts detected by vibration analysis and thermal analysis.Reliability of cockpit display and control device can be guaranteed based on reliability analysis and optimization.The effectiveness of this optimization method has been proved by the tests for environment adaptability and reliability parameters.
