An artificial teat containing a force transducer was constructed to study the forces exerted by the liner on the teat during milking. The objective was to develop a method of comparing the action of different liners under a variety of different milking conditions. The rigid structure of the artificial teat did not provide an accurate representation of a real teat but deformable models used in the past have not proved practical. Initial tests of the teat showed that it gave repeatable results during calibration. When placed in a liner, however, repeatable results could not be obtained if the teat-liner interface was disturbed. The forces that were measured under simulated milking conditions varied with liner wall position and with time. There was a peak and trough prior to a stable asymptotic value being attained and a noticeable time lag behind pulsation chamber pressure. This technique can be used to compare liners when a reliable method of locating the artificial teat within the liner has been developed.
构建了一个装有力传感器的人工乳头，以研究挤奶过程中内衬对乳头施加的力。目的是开发一种方法，用于比较在各种不同挤奶条件下不同内衬的作用。人工乳头的刚性结构不能准确代表真实乳头，但过去使用的可变形模型并不实用。乳头的初步测试表明，在校准过程中它能给出可重复的结果。然而，当放置在内衬中时，如果乳头与内衬的界面受到干扰，就无法获得可重复的结果。在模拟挤奶条件下测量的力随内衬壁位置和时间而变化。在达到稳定的渐近值之前有一个峰值和谷值，并且在脉动腔压力之后有明显的时间滞后。当开发出一种在内衬中定位人工乳头的可靠方法时，这种技术可用于比较内衬。
