RESEARCH ON PANORAMIC SURFACE DEFORMATION MEASUREMENT AND ANALYSIS METHOD FOR SPHERE STRUCTURE

  • Spherical structures, due to their outstanding mechanical properties and spatial efficiency, play a crucial role in fields such as aerospace, precision manufacturing, and civil engineering. However, the geometric characteristics of spherical surfaces—such as pronounced curvature, complete circumferential coverage, and full-field deformation—present substantial challenges for high-precision three-dimensional measurements, Existing research on spherical surface deformation measurement is currently inadequate to fulfill the pressing demands of both engineering applications and scientific research. To address this, this paper proposes an innovative multi-camera Digital Image Correlation (DIC) system architecture tailored for spherical surface measurement, a simplified, stable, and high-precision "1-6-1" multi-camera DIC system was developed and applied to pressurized deformation measurements of bamboo-woven Cuju and polymeric inflatable spheres, the system successfully performed full-circumference, full-field, high-precision deformation measurements on spherical surfaces, Through detailed analysis of the evolutionary patterns and mechanical response mechanisms of deformation fields on both Cuju and inflatable spheres, the feasibility of the "1-6-1" multi-camera DIC system for full-field deformation measurement and mechanical research on spherical surfaces was conclusively validated.
