Using the finite element method and CAD SolidWorks Simulation, the relationship between the geometric parameters of workpieces and the error in processing flat surfaces of levers caused by elastic deformations of the workpiece due to the application of holding force is established. In this paper, we developed a method for determining the error of processing flat surfaces that occurs from fixing, compiled a model for determining the error by the finite element method, and calculated the error of processing flat surfaces that occurs from fixing for workpieces with different geometric parameters. As a result of the study, the relationship between the value of the center distance of workpieces and the error in processing flat surfaces of levers caused by elastic deformations of the workpiece due to the application of holding forces was determined.

A new method which combines the holography interference technique with the finite element method for determining the distribution of vibration amplitudes and stresses of gas turbine compressor blades is presented in this paper. In comparison with the ordinary electrical strain gage method, the present method has the advantage that there is no limitation to the number of measuring points and good results can be obtained even at high order modes.
