摘要
将激光干涉法应用于冲量摆冲量测试中, 分析了主要的测量不确定度, 在测量过程中给出了相应的处理方法。在利用累计峰值个数来计算最大摆角的常规方法基础上, 新增加了一套独立、互补的数据处理方法, 使其具有双精度测试效果, 结合这两种方法可扩大适用范围并提高了测量的可靠性。
Abstract
The laser interferometry is employed in the ballistic pendulum measurement, and the main uncertainties of measurement are analyzed. In the measurement process, the corresponding treatment methods are provided. A new set of independent complementary data processing methods is added on the basis of the original method that calculates the maximum swing angle with the accumulated peak amount. The combination of these two methods has the double precision test effect and can expand the applicable scope and improve the measurement credibility.
