| 摘 要： | 本文运用流固耦合有限元法，对有润滑油存在的油底壳进行了耦合模态计算，发现润滑油的存在对油底壳的模态频率和振型影响较大。由于流体的存在，使油底壳的模态频率大幅下降，振型也发生了较大变化。本文还通过计算对上述影响进行了数值预报。

| Abstract: | The oilpan's coupled modes are calculated by applying fluid-structure coupled FEM,when some lubricating oil remains in the oilpan.It is discovered that the existence of lubricating oil affects the oilpan's modes to such extent that the mode frequency decreases dramatically and great changein mode shape appears.And the above mentioned effects can be predicted numerically via calculation. |
