| Abstract: | According to the special thin-walled rotating body structure of the thrust chamber parts, the laser scanning measurement method is applied to the non-contact measurement to avoid the measurement error caused by the contact deformation caused by the contact force in the conventional contact measurement. The cavity structure or parts' blocked can be measured by using reflection method. The inaccuracy that was generated in the coordinates exchanging can be avoided due to single station mode. In this paper, analyzes the process methods. And this method can be certificated though actual parts measurement experiments. The measurement problem of thrust chamber parts is solved effectively. Reflection laser scanning measurement method can be extended to other similar large-size thin-wall parts. |
