20.500.12556/RUL-185909 Razvoj dinamskega modela jamske kobilice (Troglophilus neglectus) za karakterizacijo vibrosenzornih mehanizmov žuželk Development of a Cave Cricket (Troglophilus neglectus) Dynamic Model for Characterization of Vibrosensory Mechanisms in Insects Žuželke se pri iskanju partnerjev in medsebojnem sporazumevanju pogosto zanašajo na substratno vezano vibracijsko komunikacijo. Te vibracije je mogoče izkoristiti tudi za namensko vplivanje na vedenje žuželk oziroma za zatiranje škodljivcev (biotremologija). Jamska kobilica (Troglophilus neglectus, red Orthoptera) je nočno aktivna vrsta, ki tovrstno komunikacijo uporablja za dvorjenje v neposredni bližini partnerja. Vibracije zaznava s subgenualnim organom v nogi. Razumevanje prenosa teh vibracij skozi nogo do subgenualnega organa je ključno za razumevanje vibrosenzornih mehanizmov žuželk in njihovega biotremološkega potenciala. Z uporabo Denavit-Hartenbergove formulacije smo razvili dinamski model kinematične verige in z lasersko vibrometrijo izmerili frekvenčne prenosne funkcije petih osebkov. Iz 30 merilnih točk najkakovostneje izmerjenega osebka smo z dvostopenjskim optimizacijskim postopkom identificirali 16 mehanskih parametrov modela. Nato smo z modelom raziskali korelacijo med pozicijo in modalnimi lastnostmi kobilice. Insects often rely on substrate-borne vibrational communication to locate mates and communicate with one another. These vibrations can also be exploited to deliberately influence insect behavior or to control pests (biotremology). The cave cricket (Troglophilus neglectus, Orthoptera) is a nocturnal species that uses this form of communication for close-range courtship. Vibrations are sensed via the leg's subgenual organ. Understanding this transmission through the leg to the organ is key to understanding insect vibrosensory mechanisms and their biotremological potential. Using the Denavit–Hartenberg formulation, a dynamic model of the kinematic chain was developed and the frequency response functions of five individuals were measured by laser vibrometry. Using the 30 measurement points of the best-measured individual, 16 mechanical model parameters were identified with a two-stage optimisation procedure. The model was then used to investigate the correlation between posture and the modal properties of the cricket. jamske kobilice modalna analiza frekvenčne prenosne funkcije Denavit-Hartenbergovi modeli vibrosenzorni organi identifikacija parametrov cave crickets modal analysis frequency response functions Denavit–Hartenberg models vibrosensory organs parameter identification true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-08-22 08:32:12 2026-08-22 08:32:17 2026-08-23 04:09:55 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 288200 48617.pdf 48617.pdf 1 5EB6EEE46F825530F69762A7B29742BD 5225ec57a477c878ed41e4b7b8dcc945b9f9a4238389c8059f76aa0632843702 d3f4f011-9df2-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244916 Fakulteta za strojništvo 0 0 0
