Dempfirovanie Kolebaniy Dissipativno-Neodnorodnykh Mekhanicheskikh Sistem

Rassmatrivayutsya lineynye mekhanicheskie sistemy s konechnom chislom ili schetnym mnozhestvom stepeney svobody. Sistema soderzhit nasledstvenno uprugie elementy. Predpolagayutsya izvestnymi raspredelenie mass sistemy, mekhanicheskie kharakteristiki deformiruemykh elementov. Stavitsya zadacha opredeleniya dissipativnykh kharakteristik i napryazhenno-deformirovannogo sostoyaniya (NDS) sistemy. Vynuzhdennye kolebaniya proiskhodyat pri nalichii impul'snykh i periodicheskikh vneshnikh vozdeystviy. Zadacha opredeleniya chastot i dekrementov sobstvennykh kolebaniy sistemy, sostoyashchey iz deformiruemykh chastey s razlichnymi mekhanicheskim svoystvami, svedena k probleme sobstvennykh znacheniy. V zadache o vynuzhdennykh kolebaniyakh vozdeystviya predpolagayutsya impul'snymi ili periodicheskimi. Podlezhat issledovaniyu dempfiruyushchie svoystva sistemy. Rassmatrivaemaya problema predstavlyaet soboy obshchuyu postanovku dinamiki dissipativno odnorodnykh i neodnorodnykh mekhanicheskikh sistem. V nastoyashchey rabote obshchaya postanovka dissipativno-neodnorodnykh sistem i metody resheniya primenyayutsya k problemam vibrozashchity, seysmostoykosti podzemnykh sooruzheniy i seysmologii.
