Imininingwane yomkhiqizo

Amathegi womkhiqizo

Isimo sokudlidliza nokuvezwa kwamagama kuvame ukusetshenziselwa ucwaningo lobunjiniyela nolwezesayensi, njengakwakhiwayo, imishini nakwezinye izinto zobunjiniyela, imvamisa kuyadingeka ukugwema isimo sokuphakama kwemisindo ukuqinisekisa ikhwalithi yobunjiniyela. Kwamanye amabhizinisi we-petrochemical, ulayini we-resonance phenomenon usetshenziselwa ukuthola ukuminyana kuketshezi nokuphakama ketshezi, ngakho-ke ukudlidlizeliswa okuphoqelelwe nemisindo kuyimithetho ebalulekile yomzimba, edume kakhulu kwi-physics kanye nobuchwepheshe bobunjiniyela Ukunakwa. Ithuluzi lisebenzisa uhlelo lokudlidliza imfoloko njengento yocwaningo, amandla kagesi kagesi kagesi othokozisayo njengamandla athokozisayo, kanye nekhoyili kagesi njengenzwa ye-amplitude ukukala ubudlelwano phakathi kokudlidliza kwe-amplitude nokushayela imvamisa yamandla, nokutadisha ngenkani isimo sokudlidliza nokuzwakala komsindo nomthetho wawo .

Ukuhlolwa

1. Fundisisa ubudlelwano obuphakathi kwe-amplitude namandla okuvama kwesistimu yokudlidliza imfoloko yokuqondisa eqhutshwa ngamandla angaphandle ngezikhathi ezithile. Linganisa futhi uhlele ijika labo lobudlelwano, bese uthola imvamisa yesonance nobukhali besistimu yokudlidliza (leli nani lilingana nenani le-Q).

2. Linganisa ubudlelwane obuphakathi kokudlidlizela nobukhulu bezingalo ezilinganayo zemfoloko yokuhlenga. Thola ifomula yobudlelwano phakathi kwemvamisa yokudlidliza f (isb. Imvamisa ye-resonance) kanye ne-block mass m enamathiselwe ezingalweni zemfoloko yokuhlenga endaweni ethile.

3. Thola ubukhulu bensimbi yamabhulokhi amaningi ananyathiselwe izingalo zemfoloko yokuhlenga ngokukala imvamisa ye-resonance.

4. Linganisa imvamisa ye-resonance nobukhali bemfoloko yokushuna lapho ushintsha ukwakheka kokudlidliza nokwandisa amandla okudambisa imfoloko yokuhlela futhi uqhathanise.

Ibhukwana lemiyalo liqukethe ukucupha kokuhlola, imigomo, imiyalo yezinyathelo ngezinyathelo, nezibonelo zemiphumela yokuhlolwa. Sicela uchofoze Ithiyori Yokuhlola futhi Okuqukethwe ukuthola eminye imininingwane ngalezi zinsiza kusebenza.
