【摘要】 基于振动的蚕茧无损检测方法的基本原理,是通过测试蚕蛹振动的能量特征值来闻接得到蚕蛹的重量.在测试过程中每次测量的结果差异较大,简单的数据处理方法会给确定振动参数指标带来困难.从统计的观点出发,分析了蚕蛹振动的特点,检验了蚕蛹振动数据的分布形式,推出了在满足一定精度条件下必需的测量次数.更多还原

【Abstract】 The basic principle of the pod’s non-destructive measuring based on vibration is that silkworm chrysalides’ weight can be indirectly obtained by measuring the vibration energy eigenvalue of silkworm chrysalides. In the process of measuring, measuring resuits differ from each other. It s difficult to deter mine vibration parameter with the norm simple data processing. Provided with certain precision the neces sary measuring times can be determined through analyzing the vibration character of silkworm chrysalides and verifying the data distribution of silkworm chrysalides’ vibration in terms of statistics.更多还原
