英文摘要: |
In order to explore the dynamic characteristics of a new type horizontal axis washing machine with inverted pendulum suspension structure, the
vibration characteristics were studied. Firstly, the force analysis of the suspension system was carried out, the axial force and tangential force of the dampers were discussed and the
mechanical description was established. Furthermore, the vibration model of the roller washing machine was established by virtual prototype, the suspension system description was
integrated into the whole machine through the secondary development, and the correctness of the simulation was verified through experiments. Finally, the dynamic characteristics of the
traditional structure, the improved suspension structure and the inverted pendulum structure were compared. The results show that the new type washing machine has a marked improvement
on transient vibration of dehydration of the washing machine. It is of great significance to vibration and noise reduction of the horizontal axis washing machine. |
