针对某舰船产品和贮运架整体结构振动试验存在的周期长、成本高等问题，提出应用商用有限元软件Ansys开展虚拟振动试验的一般方法和流程。运用此方法对整体结构开展了模态计算、谐响应分析、瞬态计算和疲劳分析等仿真计算，结果表明该方法合理可行，可完成对结构振动性能的验证，能够实现对物理振动试验中稳定性试验和耐振性试验的真实模拟。
Aimed at such problems as long period and high cost in the vibration test of the overall structure of a kind of ship product and storage and transportation frame, the general method and process of virtual vibration test using Ansys software were proposed. This method was used to carry out simulation calculations such as modal calculation, harmonic response analysis, transient calculation and fatigue analysis. The calculation results show that this method is reasonable and feasible. Based on this method, the verification of structural vibration performance could be completed, and the real simulation of stability test and vibration resistance test in physical vibration test could be realized.
