摘　　要：针对地面用干式生化分析仪在航空机载工作环境中结构强度低、易损坏失效的问题,提出了系固强度改进与隔振设计方法,并利用有限元分析和力学试验进行效果验证,改进后的强度安全裕度在1.5以上,减振效率可达到56%,设备性能指标满足质控标准,满足了航空力学要求.Due to the low structural strength and poor vibration isolation,the ground dry biochemical analyzer will suffer from damage and functional failure in the airborne working environment.A design method was proposed for the strength improvement and vibration isolation of dry biochemical analyzer,and verified by finite element analysis and mechanical tests.The results show that the strength safety margin can be more than 1.5,the vibration isolation efficiencies can be up to 56%,the performance index meets the quality control standard,and meets the requirements of aeromechanics after improvement.
