20.500.12556/RUL-102247 Optimizacija zaskočnega mehanizma za pozicioniranje palice na tripodni kontroli dostopa Optimizing the lacking mechanism for positioning the bars to tripod access control device Pri snovanju mehanizma tripodne kontrole dostopa smo se soočili z dvema problemoma. Treba je bilo določiti primerno silo za solenoidni aktivator in preveriti potencialno kritične napetosti v revolverju. Do rezultatov smo prišli z analitičnim izračunom in numeričnimi simulacijami. S preskusom prototipa smo validirali izračune in potrdili končno obliko mehanizma palice in zaskočke. Izračuni in simulacije so pokazali ustreznost drugega koncepta, pri katerem bo potrebna dodatna obdelava stične površine med zaskočko in palico, saj je treba zagotoviti koeficient trenja, ki je manjši ali enak 0,2. In the process of designing a mechanism of a tripod access control device we were confronted with two problems. First, it was required to determine the appropriate force for the solenoid actuator as well as search for any potential critical tension in the revolver. We obtained the results by using an analitical calculation and numerical simulations. As a result of conducting the prototype tests our calculations were verified and the final design of the mechanism bars and ratchet was confirmed. However, the calculations and simulations exhibited a better suitability of the second concept that does not require an additional approach regarding the contact surface treatment of the bars and ratchet, for the desired friction coeficient to be smaller than or equal 0,2. tripodna kontrola dostopa numerična simulacija solenoidni aktivator zaskočka statični preračun tripod access control device numerical simulation solenoid actuator ratchet static calculation true false false [Ž.
