某型舰载电子机柜的减振器设计

为了提高电子机柜在工作中的可靠性与稳定性,除了加强电子机柜本身的强度设计,还可以采用整体的隔振缓冲系统来提高其抗振、抗冲击能力。结合无谐振原理设计一种舰载用的新型减振器结构并计算其结构参数,利用ANSYS Workbench建立有限元仿真模型,根据舰载环境下的振动和冲击特性对其进行有限元分析,最后通过环境振动和冲击试验对仿真分析结果进行验证,结果表明所设计的减振器满足舰载环境的振动和冲击要求,并可为以后的结构参数优化和新的减振器结构的设计提供参考。

Design of Shock Absorbers for a Shipboard Electronic Cabinet

In order to improve the reliability and stability of working state of electronic cabinets, in addition to strengthening the strength of design of the electronic cabinet itself, the overall vibration isolation system can be uesd to improve its anti-vibration, impact resistance. Based on the non - resonant principle, a new type of damper structure for shipboard was designed and its structural parameters were calculated. The finite element simulation model was established by ANSYS Workbench. Additionally，the finite element analysis was carried out according to the vibration and impact characteristics in shipboard environment. Finally, the simulation results were verified by environmental vibration and impact test: the designed shock absorber met the vibration and shock requirements of the shipboard environment. Moreover，it can provide reference for the future optimization of structural parameters and the design of new shock absorber structure.
