Abstract EN
Transmission towers are structurally complex, which makes it challenging to choose the right place and number of sensors for health monitoring.
In this paper, optimal sensor placement of a cat-head-type transmission tower is conducted by using the Effective Independent Method (EIM) and a method is proposed for calculating the minimum number of sensors for structural health monitoring by combining EIM and Modal Assurance Criterion (MAC).
The method for calculating the number of sensors prescribed in this paper derives a curve that shows the relationship between MAC value and the number of sensors.
It is found that the MAC value decreases with increase in the number of sensors.
When the number of sensors reaches a certain threshold, the curve tends to stabilize.
Then, the number of sensors corresponding to the minimum MAC is proposed as the minimum number of sensors.
Through calculation, the minimum number of sensors of the cat-head-type transmission tower is obtained.
Also, the optimal sensor placement results show that the position of a large number of sensors includes the position of a smaller number of sensors.
