摘要
为了获取某轻卡燃油滤清器支架的强度性能,首先基于有限元方法建立燃油滤清器支架的离散化模型,然后激励端加载原型车采集的振动加速度,采用频率响应方法对其进行强度分析,分析结果表明其最大应力值小于材料屈服,满足强度性能要求。最后基于重力场工况对其进行强度分析,分析结果表明其最大应力也低于材料屈服,也符合设计要求,因此该燃油滤清器支架的强度特性能够满足使用要求,安全系数较高。
Aiming at obtaining the strength performance of a light truck fuel filter bracket. Firstly, the discretization model of fuel filter bracket was built based on finite element method. Secondly, the vibration acceleration of prototype vehicle exciting end was loaded, it was strength analyzed by adopting frequency response method, the analysised result showed that its maximum stress was less than yield strength of the material, it could meet strength performance requirements. Lastly, it was strength analyzed based on gravity field working conditions, the analysised result showed that its maximum stress was less than yield strength of the material, it also could meet design requirements, so its strength performance could meet the use requirements, and its safety factor was high.
