**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。

 

 

 

 

Resonant Testing Maschine TESTRONIC

 

The concept of the resonant testing machine TESTRONIC is based on the latest possibilities in resonant testing machine engineering.
Many decades of experiences in devlopingmanufacturing of resonant testing machinesalso our continuous task to support our customers in their testing needs are the benefit .

The main application for a resonant testing machine are tests with a large number of load cycles. On the machine table with T-Nuts is possible to perform complicate test arrangements. The daylight of 500 mm between the columns allows the installation of a furnace, environmental or vacuum chamber.

Resonant Testing Maschine VIBRO-FORTE

 

The resonant testing machine VIBRRO-FORTE is the latest development of RUMUL.
The design of the VIBRO-Forte 500 is based on a strict further development of the resonant system MAGNODYN. An ideal solution has be found to test long shape components like fasteners, reinforcement steel bars, etc.roundflat specimens. The changeable frequency range is between 50160 Hz depending on the stiffness of the specimen. Noteworthy is the low weight of a testing machine at this high capacity.

resonant testing machines can stress specimens or structures with a dynamic load superimposed to a static load. the dynamic load is generated by an oscillating system resonator which runs in its natural frequency. the oscillating system consists of massessprings whereas the structure or the specimen which has to be tested is also part of.
