dc.description.abstract |
In this work, a wind turbine shrink disk is used as the research object to investigate
load-carrying performance of a multi-layer interference fit, and the theoretical model and finite
element model are constructed. According to those models, a MW-level turbine shrink disk is
designed, and a test device is developed to apply torque to this turbine shrink disk by hydraulic jack.
Then, the circumferential slip between the contact surfaces is monitored and the slip of all contact
surfaces is zero. This conclusion verifies the reasonability of the proposed models. The effect of the
key influencing factors, such as machining deviation, assembly clearance and propel stroke, were
analyzed. The contact pressure and load torque of the mating surfaces were obtained by building
typical models with different parameters using finite element analysis (FEA). The results show that
the minimum assembly clearance and the machining deviation within the machining range have
little influence on load-carrying performance of multi-layer interference fit, while having a greater
influence on the maximum assembly clearance and the propel stroke. The results also show that the
load-carrying performance of a multiple-layer interference fit can be ensured only if the key factors
are set within a reasonable design range. To avoid the abnormal operation of equipment caused by
insufficient load torque, the propel stroke during practical assembly should be at least 0.95 times the
designed propel stroke, which is significant in guiding the design and assembly of the multi-layer
interference fit. |
