This article deals with the theoretical basis for design of a motorcycle frame such as geometry motorcycle, choice shape and material manufacture frame. The is devoted to use simulation tools detect critical points in using Autodesk Inventor 2020 software. results simulations were used production real an electric motorcycle.

This paper presents low cycle fatigue (LCF) life prediction of a coated and uncoated exhaust manifolds. First Solidworks software was used to model the exhaust manifolds. A thermal barrier coating system was applied on the tubes c of the exhaust manifolds, consists of two-layer systems: a ceramic top coat (TC), made of yttria stabilized zirconia (YSZ), ZrO2-8%Y2O3 and also a metallic bond coat ...

BACKGROUND Motorcycle sales, registration and use are increasing in many countries. The epidemiological literature on risk factors for motorcycle injury is becoming outdated, due to changes in rider demography, licensing regulations, traffic mix and density, road environments, and motorcycle designs and technologies. Further, the potential contribution of road infrastructure and travel speed ha...

Motorcycle exhaust (ME) is a major source of air pollution and a potential health hazard in urban areas where motorcycles are a popular means of transportation. The main objectives of this study were to determine the ability of ME to cause cardiotoxicity in rats and investigate the possible mechanisms of toxicity. Male rats were exposed to 1:10 diluted ME by inhalation 2 h daily and Monday thro...

The project aimed to investigate how hazard perception and responding is affected by level of experience as a motorcycle rider and to assess the extent to which hazard perception and responding can be improved by specific training. The literature review showed that car drivers with fewer crashes and older or more experienced drivers respond more quickly on hazard perception tasks and that at le...

Motorcycle safety was a prominent public and political issue during the 1980s largely because of the dramatic increase in the number of deaths and injuries occurring at that time, commensurate with the growth in the number of vehicles and licensed riders (Simpson and Mayhew 1991). Since then, deaths and injuries have declined steadily and, as a consequence, motorcycle safety has become a relati...

If you were to go into a motorcycle-parts department and ask them for a feedback assembly they wouldn’t know what the hell you were talking about. They don’t split it up that way. No two manufacturers ever split it up quite the same way and every mechanic is familiar with the problem of the part you can’t buy because you can’t find it because the manufacturer considers it part of something else...

We investigate how a straight skeleton can be used to approximate a motorcycle graph. We explain how to construct a planar straight-line graph G such that the straight skeleton of G reveals the motorcycle graph of M , for every given finite set M of motorcycles. An application of our construction is a proof of the Pcompleteness of the construction problem of straight skeletons of planar straigh...

Volatile organic compounds (VOCs) and oxygenated VOCs (OVOCs) were measured in Ho Chi Minh City (HCMC) Hanoi, the two largest most populous cities Vietnam. The purpose of this study is to better understand VOC atmospheric composition their role ground-level ozone formation. Online measurements a wide range other pollutants conducted using numerous instruments during different seasons (dry rainy...

This study was conducted on a motorcycle engine that already has bi-fuel, with liquid phase LPG injection. However, when conducting experiments the concentration of substances in exhaust gas, results show hydrocarbon tests different effects. It is possible to see sudden high at some point time. Over time, nozzle tip will gradually form ice around due evaporation and heat collection. When formin...
