摘要
以声振法为基础,对西瓜进行了成熟度模型假设,并用有限元理论计算和试验模态分析相结合的方法,对西瓜的振动特性及其与成熟度之间的关系进行了初步研究,取得了一些结果.
This paper deals with non destructive evaluation on watermelon. Hypothetic model of maturity is established based on the method of sound and vibration. Dynamic finite element analysis(FEA) and experimental modal analysis are applied to determine the relationship between the vibration characteristics and its maturity of watermelon resulting in some valuable results.
