Improved Dynamic Calibration Method of Micro Electronic Piezo Gauge Based on Weighing Data Fusion and Correlation

为确保微型电子测压器在高温、高压、高冲击的实测环境中的测试精度,缩短校准周期,设计了模拟火炮膛内压力环境下的微型电子测压器动态校准系统,并从"虚拟"标准测试系统的建立和测压器动态灵敏度的计算两方面介绍了原始和改进的动态校准方法。对比分析其结果可知,改进的动态校准方法不仅能提高微型电子测压器的测试精度,而且能有效缩短校准周期,从而验证了改进的动态校准方法的可行性和合理性。

To guarantee testing precision of micro electronic piezo gauge in the test environment of high temperature, high pressure and high impact, and to reduce calibrating period, its dynamic calibration system under the simulation environment of artillery chamber pressure was designed, and two dynamic calibration methods were presented through establishing the virtual standard testing system and calculating its dynamic sensitivity. The results show that the improved dynamic calibration method can improve its testing precise and reduce calibrating period, and verify the feasibility and rationality of improved dynamic calibration method.
