UD Unholtz-Dickie

UD振動機《全世界最好的振動機系統》

主要用於實驗室的振動模擬,對待測物產生一個預先規劃好的振動時域訊號施加破壞應力藉以了解及評估待測物的容許破壞及法規允收標準

它利用一個振動機本體,內有直流線圈及交流線圈,產生磁場及相對的力,使得Armature可以上/下運動產生振動激勵,並且透過一個旋轉機構,使得振動機可以執行X,Y,Z等三軸向加載在測試物上,甚至於45°的特別振動角度要求加載

 

它可以執行的應用有

Mil-Std Testing

Package Testing

Environmental Stress Screening

Accelerated Life Testing
