Based on the theory of structural sound intensity and the two development in ANSYS, the calculated values are extracted. The vibration energy transmission was visualized by the 3D vector diagram of its related structure established through originPro. The finite element model of the underground powerhouse of a pumped storage power station was established. The sound intensity of each floor of the powerhouse under the action of spiral shell pulsation was extracted and calculated under the two working conditions of power generation and pumping. The transmission path of vibration was analyzed and visualized. The results showed that: Under the condition of power generation, the transverse and downstream vibrations from the spiral case flow channel gradually transfer to the side wall columns, but still mainly wind shield, whereas the left and right bank columns accounted for 70.02% in the vertical vibration transmission. Under pumping condition, the transverse and along-river vibration transmission is dominated by the left and right bank columns, and the vertical vibration transmission is dominated by the wind shield, accounting for 61.22%, which is just opposite to the power generation condition.
