Error Comparision of High-Voltage Electrostatic Voltmeter in AC and DC Measurement 高压静电电压表工频和直流电压的误差比较
Study on Verification of Non-contact Electrostatic Voltmeter 非接触式静电电压表校验研究
In this thesis, one method to measure the stress distribution and one method to measure the SIFs of mode I and mode II cracks using PVDF films and an electrostatic voltmeter of non-contact type are proposed. Experiments were performed to validate those methods. 本论文提出了应用PVDF压电材料和非接触型静电电压表测量裂纹尖端应力分布和Ⅰ,Ⅱ类型裂纹的应力强度因子的实验方法。
