| Abstract: | In order to solve the loading measurement problem in special structure static test, the design method of static test based on PVDF piezoelectric film is introduced. According to the features of PVDF film and static test, calibration method for PVDF sensor with gasbag is given. Finally, a cylindrical shell test with radial pressure is conducted to validate the effectiveness of present method. |
