AI Technical Summary

Technical Problem

In the process of aero-engine assembly, when it is necessary to detect runout of precision surfaces in complex configurations and conditions, different measuring equipment needs to be customized, which leads to waste of resources and low detection efficiency. Moreover, the finite-point measurement method has many error factors and is difficult to optimize.

Method used

The Monte Carlo method is used to generate simulated data. The true concentricity and error concentricity are calculated from the simulated data. The measurement point location and equipment error are taken into account to optimize the finite point measurement method.

Benefits of technology

It improves the accuracy and efficiency of aero-engine circular runout measurement, increases the assembly qualification rate, and provides a basis for optimizing finite-point measurement methods.
