Pētot velosipēda un braucēja kustīb

Pētot velosipēda un braucēja kustības stabilitātes jautājumus bija interesanti apskatīt, kā divriteņa rāmi ietekmē velobraucēja radītās slodzes, ja tiek izvēlēti trīs dažādi divriteņa rāmja materiāli. Divriteņa rāmja modelis ir izveidots 3D CAD (Computer-aideddesign) virtuālajā vidē programmā SolidWorks. Rāmja rasējumu var apskatīt pielikumā nr. 5. Par pamatu divriteņa rāmja projektam tika izmantots 20 collu kalnu divriteņa rāmis, kas paredzēts 28 collu ratiem. Divriteņa rāmja ģeometrija veidota no interneta resursiem iegūta Fantom 29er modeļa bāzes, izmantojot tā pamatizmērus, pārējie parametri ņemti no rokasgrāmatas HandbookforBicycleMechanics. [25] Pētījumā rāmja konstrukcija sastāv no dažāda diametra caurulēm, kuras SolidWorks Simulation statiskajā analīzē definētas kā čaulas. Darba mērķis ir noskaidrot, kā mainīsies statiskās analīzes rezultāti, mainot divriteņa rāmja materiāla īpašības.
Attēlā 5.3. var apskatīt, kā tiek pieliktas slodzes rāmim. Tiek pieņemts, ka divriteņa rāmis tiek fiksēts divās pozīcijās: aizmugurējā rata stiprinājuma vietā fiksējot to, kā nekustīgu savienojumu un vietā, kur paredzēta priekšējās dakšas slodzes ietekme ar elastīgu fiksāciju, pieņemot, ka dakša ir ar amortizatoru. Pielikto slodžu lielumu un sadalījumu var apskatīt attēlā 5.4.

Researching the bike and rider movement stability issues was interesting to see how the bike frame affects the resulting load velobraucēj if you select three different bike frame material. Bike frame model is created in a 3D CAD (Computer-aideddesign) virtual environment in SolidWorks. Frame drawing can be viewed in annex No. 5. On the basis of a bike frame project was used 20-inch mountain bike frame for 28 inch wheel. Bike frame geometry made of internet resources get a Phantom 29er models base, using the principal dimensions of the rest of the parameters taken from the Guide HandbookforBicycleMechanic. [25] the study frame construction consists of different-diameter pipes that SolidWorks Simulation static analysis defined as the shell. The objective of the work is to find out how to change static analysis results by changing the bike frame material properties.In the picture you can see how 5.3 is applied to the load frame. It is assumed that the bicycle frame are fixed in two positions: rear wheel mounting location sensing how rigid connection and where the front forks for loading effects with flexible fixation, assuming that the fork is with shock absorber. Loads applied to the size and distribution can be viewed in Figure 5.4.

Researching the bike and rider motion stability issues it was interesting to see how the bicycle frame affects cyclists pressures when selected in three different bicycle frame materials. Bicycle frame model is created in 3D CAD (Computer-aideddesign) program SolidWorks virtual environment. Frame drawings can be viewed in Annex no. 5. On the basis of the bicycle frame design was used in 20-inch mountain bike frame for 28-inch cart. Bike frame geometry is made ​​up of Internet resources obtained Fantom 29er model-based, using the principal dimensions, other parameters taken from the manual HandbookforBicycleMechanics. [25] The study frame construction consists of different diameter pipes for SolidWorks Simulation static analysis defined as shells. The goal is to find out how to change the static analysis results, changing the bike frame material properties.
Figure 5.3. can be viewed as being applied in a time-frame. It is assumed that the bicycle frame is fixed in two positions: the rear wheel attachment instead of fixing the rigid coupling and the place where the intended effect of the front fork load with flexible fixation, assuming that the fork is a shock absorber. Applied load size and the distribution can be seen in Figure 5.4.
