摘要
基于Hyper Works软件采用等效质量法对该油底壳空壳、含3.5 L机油和含7 L机油状态进行有限元约束模态的求解。最后结果表明,随着机油量的增多,对油底壳的固有频率和振型有较大影响。
Based on the HyperWorks software, equivalent mass method was used to solve the finite element constrained modal of the empty shell, 3.5l oil and 7L oil. The results show that the natural frequency and mode of the oil sump are greatly affected by the increase of oil volume.
