To calculate the shafting load distribution, a mechanical model for shaft alignment was set up based on strain and transfer matrix method, with which actual bearing load and elevation were calculated by measuring the section strain values, while the influence coefficients of hearing load measured by changing the bearing elevation. Results show that the actual measurements agree well with that of the theoretical calculation, proving the strain and transfer matrix method to be effective, which has many ad- vantages such as easiness in implementation, effectiveness in modularity and strong ability in dealing with complex structures.
