This paper gives an amended stiffness model of simple beam. Single-cylinder hydraulic machine upper beam as an example, amended stiffness model is established. Using orthogonal test method to determine the test program and carrying out finite element analysis to each test program. For the purpose of constructing the amended simply beam stiffness model, the overdetermined equations is established. By solving the overdetermined equation, the amended simply beam stiffness model is obtained. The error between the amended stiffness model results and the finite element analysis is less than 20%, so the amended model has certain validity.
