摘要

三坐标测量机在机械零件的高精度检测中得到了广泛的应用。为了提高航空发动机叶片廓形测量的效率和精度，研究了一种基于萤火虫算法的航空发动机叶片廓形测量采样方法。然后，在一次仿真中与等弧长采样算法(EAS)和等参数采样算法(EPS)进行比较，表明所提采样算法的采样质量优于其他两种算法。最后，通过叶片型线的实验验证了该算法的有效性。仿真和实验结果均表明，该方法可以通过测量较少的点来保证测量精度。

A sampling method based on improved firefly algorithm for profile measurement of aviation engine blade

Coordinate Measurement Machines (CMMs) have been extensively used in inspecting mechanical parts with higher accuracy. In order to enhance the eﬃciency and precision of the measurement of aviation engine blades, a sampling method of proﬁle measurement of aviation engine blade based on the ﬁreﬂy algorithm is researched. Then, by comparing with the equal arc-length sampling algorithm (EAS) and the equi-parametric sampling algorithm (EPS) in one simulation, the proposed sampling algorithm shows its better sampling quality than the other two algorithms. Finally, the eﬀectiveness of the algorithm is veriﬁed by an experimental example of blade proﬁle. Both simulated and experimental results show that the method proposed in this paper can ensure the measurement accuracy by measuring a smaller number of points.
