Abstract

In order to improve the accuracy and reliability on measuring grain loss, a research scheme of dynamic strain sensing using piezoelectric patches is put forward. Kinetic model of the grain and straw impacting sensor is analyzed by vibration theory of plates and shells, vibration model about sensitive element of the grain loss sensor is set up. The paper discusses the vibration shape and distribution of dynamic strain about low order modes of sensitive element in order to choose the sensing position of piezoelectric patches reasonably and construct piezoelectric sensor arrays. The grain and straw impacting sensor is proceeded on test bench. The analysis result is compared with the measure result obtained by the dynamic signal analyzer, the conclusion showed experiment results is well coincided with theory results. These are help to devise monitor for grain loss of combine and amend its parameters.
