Zasnova krmilnega ter merilnega sistema laboratorijske naprave ročičnega mehanizma

Vozelj, Vid (author), Čepon, Gregor (mentor)

Kinematika je veja mehanike, ki se ukvarja z gibanjem telesa ali sistema, pri čemer ne analizira vzrokov za nastanek gibanja. Sistemom, ki jih preučuje kinematika, pravimo mehanizmi. Sem spada tudi ročični mehanizem, ki je eden najpogostejših pretvornikov gibanja, hkrati pa je tudi odličen primer za razlago kinematičnih veličin. V ta namen smo izdelali napravo z vsemi potrebnimi pogonskimi in senzoričnimi elementi, ki so potrebni za merjenje kinematičnih veličin ročičnega mehanizma. Izhajali smo iz že prej izdelanega ročičnega mehanizma in ga prilagodili našim ciljem. Dodali smo mu mikroračunalnik z zaslonom na dotik, s katerim bomo prikazovali meritve in krmilili koračni motor, ki smo ga uporabili kot aktuator za ročični mehanizem. Krmiljenje in prikazovanje se bo izvajalo s pomočjo grafičnega vmesnika, ki smo jo izdelali s pomočjo programskega jezika Python. Izmerjene vrednosti naše naprave smo primerno ovrednotili ter jih primerjali s teoretičnimi vrednostmi.

• Title: Design of the control and measuring system for the laboratory lever mechanism

Abstract

Kinematics is a branch of mechanics that deals with the motion of bodies or systems without analyzing the causes of motion. Systems studied by kinematics are called mechanisms. This also includes the lever mechanism, which is one of the most common transformers of motion, and at the same time a great example for explaining kinematic variables. For this purpose, we made a device with all the necessary drive and sensory elements, needed to measure the kinematic sizes of the lever mechanism. We started from a pre made lever mechanism and adjusted it to our goals. We added a microcomputer with touch screen, to display the measurements and control the stepper motor, which we used as an actuator for the lever mechanism. Control and display are performed using a graphical interface created using the Python programming language. The measured values of our devices were appropriately evaluated and finally compared with theoretical values.
