摘要目的研究运输过程中梨因振动引起的损伤以及其粘弹性的变化。方法利用振动台模拟运输条件，用DASP对信号进行采集并进行分析，用质构仪对梨果实进行粘弹性分析，并建立相应的流变模型，进行参数识别。结果梨果实的损伤体积和加速度传递率随振动加速度的增大而增大，随频率的增大而减小；梨果实的蠕变量随振动时间的延长而增大，随振动频率的增大而减小；相同振动加速度下低频对梨果实的运输最为不利，相同振动频率，振动加速度越大，对梨损害越严重。

Abstract：Objective Study damage caused by vibration and the changes of viscoelasticity of the pear in the process of transportation. Transportation is simulated with vibrator. Method Signals are collected and analyzed by DASP, viscoelastic analysis of pear was tested by a texture analyzer and the corresponding rheological model was established. Result The damage volume and acceleration of pear fruit increased with the increase of vibration acceleration and decreased with the increase of frequency; The creep of the pear fruit increased with the vibration time, and decreased with the increase of the vibration frequency; under the same vibration acceleration, low frequency was detrimental to the carriage of pear. Under the same vibration frequency, the stronger the vibration intensity was, the more serious the damage to pears.

Key words： pear acceleration transfer ratio the damage volume creep
