In this paper, the basic principle, secondary software development and practical application of viscous damper vibration reduction technology are studied. The viscous damping coefficient velocity function equivalence method is used, and the secondary development is carried out in the finite element software ANSYS through program compilation, and the operation interface of the velocity function equivalence method is established. On this basis, the complex vibration problems of an existing building are studied, and the arrangement and installation of viscous dampers are guided on site. Through comparative analysis, it is concluded that the UIDL program and APDL macro command stream in the finite element software ANSYS can be used to establish the operation interface of the speed function equivalent method, which makes the method have better applicability and operability, improve the work efficiency and facilitate the popularization and application. By adopting the nonlinear viscous damper damping technology, before the structure and equipment produce strong vibration, the damper first enters the energy dissipation state, produces large damping, greatly consumes vibration energy, and rapidly attenuates the dynamic response of the structure and equipment to ensure the safety and normal use of the structure and equipment. The field dynamic test results and the finite element analysis results both show that the viscous damper vibration reduction technology based on the velocity function equivalent method has a significant vibration reduction effect, and is an effective means to solve the existing building vibration problems.
