Abstract
The invention relates to a three-axis high-impact sensor calibration adapter device based on a Hopkinson rod, and belongs to the technical field of weapon testing. Specifically, it includes the Z-direction anvil body calibration adapter device for Z-axis shock sensitivity and X-axis and Y-axis lateral sensitivity calibration, and the XY-direction anvil body calibration transfer device to realize Y-axis shock sensitivity and X-axis and Z-axis lateral sensitivity calibration. Calibration, or calibration of X-axis shock sensitivity and Y-axis and Z-axis transverse sensitivity; applied to the calibration experiment of Hopkinson rod high shock acceleration sensor, two sensor calibration adapters jointly complete the calibration of the calibrated high shock three-dimensional MEMS acceleration sensor Calibration of three-axis shock sensitivity and three-axis transverse sensitivity; can accurately obtain the relationship between each axial response and transverse response of high-impact three-dimensional MEMS acceleration sensors; has the advantages of strong shock resistance and high overload resistance.
Description
technical field The invention relates to a three-axis high-impact sensor calibration adapter device based on a Hopkinson rod, and belongs to the technical field of weapon testing. Background technique With the rapid development of high technology and its wide application in the military field, the use of precision guided weapons to focus on and destroy important military targets, economic targets and other targets with strategic potential in the battlefield is a major aspect of high-tech local wars. features. Due to the huge impact and damage effect of the ground-penetrating explosion on the target, it is one of the important technologies to improve the power of weapons to vigorously develop various hard target penetrating weapons, especially deep-penetrating weapons. In the ground penetration test of hard target penetration weapons, it is of great significance to understand the impact dynamic characteristics of the projectile and target interaction process for the developm...
