| In view of the problem that the traditional process method was difficult to remove the axile interference fitting parts and
easily cause damage to the fitting surface，a new kind of disassembly system was designed according to the power and transmission
characteristics of ultrasonic vibration. The interference fitting parts decomposed from the shaft parts under the combined action of axial force
and high frequency axial vibration. The vibrator of system was designed mainly by the transfer matrix method. Through the comparative test
of vibration disassembly，the disassembly effect was verified from the peak value of the disassembly pressure，the surface temperature and
the surface quality of the test article. The test results show that ultrasonic vibration can effectively reduce the axial disassembly force required
for decomposition，improve the disassembly efficiency of the axile interference fitting parts，and will not cause damage to the fitting surface. |
