**高频疲劳试验机歷史沿革

**高频疲劳试验机歷史沿革
Max E. Russenberger,現代諧振式試驗科技之父,及高频疲劳試驗機的原型機发明人。
1.在三○年代末期,Max E. Russenberger先生首先接觸到這類的測試技術。後來,他成為儀器公司Alfred J. Amsler &Co.的資深主任工程師,在那裡他*設計諧振式測試系統,而獲致了世界性的成就。
2.在1964年,Max E. Russenberger成立了自己的事業。他新公司Z獨特的目標,在設計和製造動態材料試驗系統。而其Z主要的產品系列,便是高頻諧振式振動器,換言之,就是諧振式試驗機。
3.後來,之前在Amsler的同事Erwin Muller也加入了公司,成為事業上的夥伴。而RUMUL這個名稱,便是來自他們名字上的縮寫。
4.在1978年,Roland Berchtold接手公司經營。從此,公司正式名稱改為RUSSENBERGER PRUFMASCHINEN AG。但RUMUL的簡稱仍然繼續沿用。
5.在1989年,公司遷居到Rhinefall附近的Neuhausen,空間比較寬裕的新地點。
諧振式試驗機的概念由Max E. Russenberger在1938年所創立。
在1995 Jurg Berchtold加入公司,負責軟體撰寫及產品開發
Roland Berchtold成功地改良了先前的系統觀念。目前的結構體在使用上可做泛用型的搭配,為零件測試方面開創了嶄新的契機。
工作原理
1.諧振式試驗機利用動態荷重重疊於靜態荷重上,能施加應力於試片或結構上。
2.動態荷重係由振盪系統 諧振器依自然頻率作動所生成。此一振盪系統包括砝碼及彈簧,而整個結構及測試試片也組成份子之一。
3.在這裡討論的機器一般是使用全共振量;也就是說,操作點是位於共振曲線上的頂點。諧振器事實上是由電磁系統所誘發。
4.由於共振的結果,功率消耗非常低約20到500瓦特。工作頻率則是在 50 到 600 cps
應用與優勢
1.此機器經常用於疲勞測試S/N-曲線,或是壞力學上,諸如預裂性或裂紋成長測試。 這是和伺服油壓機種比起來,這種裝備的優點。
2.對所有高負荷周期數的測試來說,諧振式試驗機是Z有利的運用。因為高試驗頻率可以有效縮短試驗時間,降低功率能源的消耗。
3.伺服油壓機種有伺服缸、伺服閥和油壓幫浦,跟它比起來,諧振式試驗機因為有耐磨的結構,並不需要維修保養,自然也降低了維修保養上的成本支出。
