【摘要】 避免水果运输过程中产生共振,是一种非常有效降低水果损伤的方法,对水果的保鲜具有重大意义。本文设计了基于虚拟仪器技术的水果运输损伤诊断系统,并用该系统对"京欣一号"西瓜进行了固有频率检测,其基频范围为139.4-173 Hz,进一步研究发现西瓜的含糖量越高,其基频越低,此研究结果为该品种西瓜的包装、运输和减振方案提供了依据和参考。更多还原

【Abstract】 To avoid frequency resonance of fruit during its transportation,the natural frequency of fruit must be known.The diagnosis system based on virtual instrument technology for fruit bruising during its transportation has been developed,and it can be used to detect the natural frequency of fruit.As system’s application,the natural frequency of"Jingxin No.1"watermelon was measured,the range is from 139.4 Hz to 173 Hz,and the natural frequency of watermelon is lower when it has higher sugar content.The result is useful to packaging, transportation and reducing vibration damaged for"Jingxin No.1"watermelon.更多还原
