落搥試驗機的原型 The prototype of the drop test 南 臺 科 技 大 學 Southern Taiwan University
前言 本落槌試驗機用來模擬測試物品掉落或是撞到的測試,目前主要測試物品是水果,測試完可將水果切片觀察水果損壞之面積大小等,以及使用示波器可以得到時間與電壓之資料。 The drop test machine used to simulate the test items falling or hit, the main test items are fruit, make fruit slices when finished testing, we can observe the size of the fruit was damaged, as well as the use of an oscilloscope can be time and voltage data.

結論 以不同的高度來進行落槌試驗,可得知測試時所需之最大電壓,以及從切片水果的損壞程度,可判斷落槌墜落高度與水果損壞程度和最大電壓成正比。 At different heights to drop test, the test result data is the maximum voltage, and the extent of damage from sliced fruit, so the height of the drop fall and fruit extent of damage and maximum voltage are direct ratio.
