A. High Frequency Pulsator POWER SWING MOT高頻動態(tài)疲勞試驗機(jī)技術(shù)資料 由優(yōu)鴻專業(yè)技術(shù)工程師為您提供
The resonance-testing-machine POWER SWING is a universal testing-system with an unbalanced mass exciting system. The system provides fatigue testing capabilities for axial, bending and torsion load. The vibration system is designed as a three-mass-system. In order to vary the testing frequency additional masses are available. The dynamic drive is done by an unbalanced mass drive which drives the flexible SPRING ACTION system. The controlled static load is introduced by a gear motor which drives a ball screw spindle. The static drive unit is mounted beneath the mounting table and offers adjustable limit switches. In the set up mode the static drive unit can be operated with a manual control. The force value can be displayed on the display of the control unit. The test system can be used force, displacement or strain controlled.
The testing machine will be delivered with a flange-type load cell as standard. Additional transducers (displacement, strain) are available.
POWER SWING MOT是通用的試驗系統(tǒng)，由不平衡電機(jī)提供激勵驅(qū)動。疲勞試驗機(jī)可進(jìn)行軸向、彎曲和扭轉(zhuǎn)載荷的疲勞試驗（需配合夾具）。共振系統(tǒng)在3組質(zhì)量體系的基礎(chǔ)上設(shè)計而成。動態(tài)載荷由不平衡電機(jī)加載，靜態(tài)載荷由齒輪/鏈條變速電機(jī)加載。
靜態(tài)驅(qū)動單元安裝在試驗臺下部，并且提供可調(diào)節(jié)的限位開關(guān)。靜態(tài)驅(qū)動單元可以手工控制，試驗載荷可以在控制系統(tǒng)的顯示器上顯示。系統(tǒng)可以以載荷、位移和應(yīng)變控制來操作、試驗。試驗機(jī)在交貨時將會配置一個標(biāo)準(zhǔn)的法蘭盤形式的試樣。系統(tǒng)可以附加位移、應(yīng)變傳感器。
The design of our high frequency pulsator series POWER SWING contains some innovations, described in the following:
特點
Test area and mounting table enlarged about 1.5 times
共振時外力做功的效率達(dá)到*，此時系統(tǒng)內(nèi)的彈性能與運動能互相轉(zhuǎn)化，外力僅用于克服阻尼力（相位相反）所以功耗極低。設(shè)備保證測量數(shù)據(jù)可靠性和準(zhǔn)確度,安全穩(wěn)定。
Huge testing strokes up to 8/10 mm
Frequency range 30…115 Hz, changing of the frequency range is possible
共振式疲勞試驗機(jī)由于工作頻率高，所用試驗時間可顯著縮短.電機(jī)共振式高頻動態(tài)疲勞試驗機(jī)頻率可達(dá)150Hz
Modern and ergonomic design
High optimum ergonomic
Digital controller with real-time processing
Usage of carrier-frequency measuring amplifier
Unsensitive to lateral forces, that means the POWER SWING is the worldwide unique Component resonance testing machine, which is also usable for asymmetrical gripping devices
Improved acoustic qualities, by build-in the swinging head into the system table and using sound insulation
Durable, fatigue strength proof and maintenance free dynamic excitation system with unbalanced motor drive
Extremely high accuracies
High control accuracy, due to optimized control routines
very accurate controlling of the static drive, due to servo drive
New extensive software – Modules for almost all applications
LCF tests
Classification according the Rainflow method
RANTEC-Technology, service load test simulation
Evaluation software LabMOTION for statistical analysis like s/n curves (Wöhler-curves) and stair case step tests
對于， 系統(tǒng)提供位移、頻率偏差檢測功能。在測試中，一旦試件萌生初始裂紋，共振頻率會發(fā)生偏移，一旦到達(dá)設(shè)定的頻率偏移值，會自動停機(jī)，同時可從監(jiān)視器上實時檢測曲線可以觀察到頻率和載荷的變化。之后，通過探傷劑對試件探傷，很容易找到裂紋萌生位置和長度
Different layouts for test protocols available
Hierarchical operator management (definition of different usage rights, for example calibration function)
Digital working hour meter (free configurable with intervals, alerts for calibration, reset able)
Very easy and intuitive operation of the system
Extremely low testing costs (less than 1% compared to servohydraulic testing machines) 由于試件產(chǎn)生裂紋導(dǎo)致剛度下降進(jìn)而引起共振頻率下降，據(jù)此控制系統(tǒng)可設(shè)置自動停機(jī)，如：共振頻率下降1Hz，系統(tǒng)判定為試件失效。這樣，一批試件的失效標(biāo)準(zhǔn)將統(tǒng)一，對均值壽命、標(biāo)準(zhǔn)差的估計更為準(zhǔn)確。設(shè)備有安全停機(jī)和緊急停機(jī)保護(hù)功能,并在停機(jī)后加載系統(tǒng)自動卸載的功能
Automatically crack recognition, due to frequency drop method (resonance principle)設(shè)備不要求很大的場地，特殊設(shè)計的地基，運行中噪聲也很小，因此，便用方便，搬運容易、對環(huán)境污染小。設(shè)備可連續(xù)工作。
