Abstract

A találmány tárgya legalább két irányban változást érzékelő giroszkóp.Lényege, hogy tartalmaz közös tengely (A) körül elterülő belső éskülső peremmel határolt, lényegében síkbeli, gyűrű vagy abroncs alakúvibrációs rezonátorelemet, a rezonátorelemet cos n1Q (ahol n1 <2 egészszám) síkbeli vivőmódusban megrezegtető kialakítású vivőmódus-gerjesztő egységet, a rezonátorelemet rugalmasan megtartótartóegységet, amely tartóegység a rezonátorelemet a tartóegységhezképest a vivőmódus-gerjesztő egység hatására rezgésbe jönni engedőnvan kiképezve, továbbá a rezonátorelem síkbeli kitérését érzékelővivőmódus-érzékelő egységet, valamint a rezonátorelemnek a giroszkópx-tengely körüli elfordulására válaszképpen adott cos nQ (ahol nértéke n1+1 vagy n1-1) nemsíkbeli válaszmódusbeli kitérését érzékelőx-irányú válaszmódus-érzékelő egységet és a rezonátorelemnek agiroszkóp y-tengely körüli elfordulására válaszképpen adott sin nQ(ahol n értéke n1+1 vagy n1-1 és megegyezik az x-irányú válaszmódus n1értékével) nemsíkbeli válaszmódusbeli kitérését érzékelő y-irányúválaszmódus-érzékelő egységet.
