In this paper,the three dimensions finite element analysis on a 2 pad tilting pad bridge bearing load cell in large turbine generator sets has been made.The influence of the boundary condition on the stress or strain field of sensor is studied.The results from the study shows that the finite element models are correct,possess better calculation precision and it is can be used to the optimal structural design on a 2 pad tilting pad bridge bearing load cell.
