Izmera vodil freze na zaletišču Letalnice bratov Gorišek : magistrsko delo

Mikelj, Teja (author), Koler, Božo (mentor), Urbančič, Tilen (co-mentor)

Na Letalnici bratov Gorišek se za izdelavo zaletne smučine uporablja freza. Njen položaj se regulira z bočnima vodiloma, po katerih se ta premika. Detajlne točke za določitev geometrije vodil so določene na mestih, kjer so pritrdilni vijaki. Dosedanja kontrola položaja vodil, ki vključuje izmero vrha vodila, se izvaja s klasično polarno izmero. V magistrskem delu smo kot alternativno in inovativno možnost predstavili uporabo nastavka s tremi prizmami Leica GMP 101. Konstrukcija nastavka omogoča enolično določitev središča vodila. Določili smo funkcijski in stohastični model izravnave koordinat karakteristične točke nastavka po metodi najmanjših kvadratov ter testirali njegovo splošno uporabo. Primerjali smo razlike med obema metodama, ter ocenili skladnost posamezne metode s projektiranimi vrednostmi. Ugotovili smo, da v splošnem obe metodi podajata podobne vrednosti razlik od projektirane krivulje. Metoda izmere z nastavkom je primerna za določanje položaja detajlnih točk vodil freze.

• Title: Measurement of technical device's rails at the inrun on the Flying hill of Gorišek brothers : master thesis

Abstract

At the Flying hill of Gorišek brothers a technical device is used to make the inrun. Its position is regulated by the lateral rails on which it moves. The detail points for determining the geometry of the rails are placed on points with the screws, determined by the top of the rail. Current control of the rail position is carried out by the polar surveying method. In our master’s thesis we present using a platform with three prisms Leica GMP 101 as an alternative and innovative possibility. The construction of the platform enables unique determination of the center of the rail. We determined the functional and scholastic model of the coordinates of the characteristic point of the platform adjustment according to the least square method and tested their general use. We compared the differences between the two methods and evaluated the compliance of individual methods with the design values. We found out that in generally both methods give similar differences from design curve. Method with platform for three prisms is suitable for determining position of detail points of tehnical device.
