AI Technical Summary
When PVDF sensors are used for explosive impact load testing, the error capacitance affects the test results, leading to inaccuracy and reduced reliability. Existing technologies have failed to effectively measure and optimize the impact of this error capacitance.
An appropriate impact test setup was used to simulate the explosive load. Voltage signals were acquired using a parallel capacitor and an oscilloscope. The impact of the error capacitance on the test results was calculated. The error capacitance value was measured using a charge-time curve comparison method. The test circuit was optimized to improve accuracy.
It provides a quantitative assessment of the impact of error capacitance on test results, improves the accuracy and reliability of test results, simplifies the operation process, and has wide applicability.
