根据某双层开启桥的综合性能要求，设计了一种液压悬挂系统。通过模拟某沿海地区的风载历程及悬挂系统竖直载荷，并基于 workbench 及 Fe-safe 软件对悬挂系统做了二轴疲劳分析。分析结果表明，悬挂系统能承受的最小载荷谱块数为1×107＞36500块（100年），满足疲劳要求。它采用workbench及Fe-safe联合仿真对液压悬挂系统进行疲劳分析，为类似多轴疲劳问题分析提供了思路。

A hydraulic suspension system was designed according to the overall performance requirements of a double bascule bridge. Two shaft fatigue analysis of the hydraulic suspension system was performed based on workbench and Fe-safe after the wind load history of certain coastal area and the vertical load of the suspension system were successfully simulated. The result shows that the suspension can bear load spectrum blocks 1×107 pieces which is bigger than the number of load spectrum blocks of the design lifetime(36500 pieces of 100 years). The workbench and Fe-safe were used to perform the fatigue analysis of the hydraulic suspension system which can provide ideas for the analysis of similar multiaxial fatigue problems.
