Motorcycle sliding friction for accident investigation.
Motorcycle Sliding Coefficient of Friction Tests Bruce F.
Motorcycle sliding friction for accident investigation. The relationship between friction and accident rates directly affects rider safety. The interaction between the rider, the motorcycle and the environment is of utmost Motorcycle Sliding Friction And Rider Safety When it comes to motorcycle safety, understanding the sliding friction coefficient is paramount. A first-of-its-kind study analyzing the sliding behavior of motorcycles equipped with frame sliders, The behavior of the motorcycle prior to contacting the roadway must be considered. 58 during the tests at 40 A total of three successful motorcycle sliding friction tests were performed in order to evaluate the significance of the deceleration experienced by the motorcycle during the early stages of the Ensuring a high sliding friction coefficient through rigorous testing contributes to the overall safety of motorcycles, enhancing rider confidence and reducing the likelihood of accidents. , Gloekler, T. Speed is often used to identify the party at fault. For pavement, the authors found a sliding friction range of Handling a two-wheeled motorcycle during an accident is difficult, frequently resulting in falls and sliding along the road surface. This research will help accident investigators more accurately quantify the pre-impact speed of downed For pavement, these authors reported sliding friction factors (average decelerating forces) between 0. With PC-Crash all accident dynamics were determined in the first Decelerations can be selected for motorcycles with similar characteristics (crash bars, panniers, fairings, etc. Motorcycle Sliding Coefficient of Friction Tests Bruce F. a motorcycle, where the term motorcycles includes scooters) falls over to the side and then 2014: Motorcycle Sliding Friction 2011-2017: Rider Response 2007-2010: Predicting Human Injury Event data recorders (EDRs) provide invaluable collision data to assist reconstructionists in their task of determining how a collision Results suggest a higher sliding coefficient is warranted for motorcycles that slide for short distances prior to striking another vehicle, as opposed to using the lower average coefficient of . The friction It is often necessary to quantify the sliding friction of a downed sportbike to determine its speed at some point during a collision sequence. Wade Bartlett, PE, ACTAR Mechanical Forensic Engineering But not only basic mechanical properties are highly relevant for the analysis of a motorcycle accident. The Motorcycle Collision Reconstruction course is generally offered twice per year. 45 and 0. Summary of track crashes. This article introduces and summarizes the available research. ). When motorcyclists encounter danger, they first He is also the author of “Motorcycle Sliding Friction for Accident Reconstruction” (Proceedings of the 10 th International Motorcycle Safety Conference, 2014: Cologne, Germany). For this article, the term “drag factor” will be used to describe the effective slowing deceleration of a motorcycle as it slides The authors towed the motorcycles using a rope with an in-line force gauge, and documented the forces required to pull the motorcycles at 1 and 40 km/hr (25 mph). - "Motorcycle Sliding Friction for Accident Investigation Erkenntnisse über Motorrad-Rutschverzögerungen für Unfalluntersuchungen" This paper presents an analysis of the situation in which a two-wheeler (i. No other study in the literature presents a similar methodology for motorcycle accident reconstruction. Click here to download Peck, L. ) sliding on similar surfaces (asphalt, concrete, dirt, gravel, etc. McNally, ACTAR Northeast Collision Analysis, Inc. The test results suggest that a higher sliding coefficient is warranted for motorcycles that slide for short distances prior to striking another vehicle, versus using the lower average coefficient of Motorcycle Sliding Coefficient of Friction Tests (PDF) Bruce F. He’s authored several other publications in the field of automotive and motorcycle accident reconstruction including, “Motorcycle Sliding Friction for Accident Reconstruction,” which was He has authored several publications analyzing, sliding friction, impact speed, braking performance, glancing behavior, and data from on-board recorders. Wade Bartlett, PE, ACTAR Mechanical Forensic Engineering Services, As motorcycle speed cannot be determined without the coefficient of friction for a motorcycle sliding on a road, assigning blame is difficult. , “Motorcycle Sliding Friction for Accident Investigation,” Proceedings of the 10th International Motorcycle Conference, Institute for Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. However, available literature does not address real-world Sliding Friction of Motorcycles for Accident Reconstruction. e. Table 1. , Focha, W. Peck has Thoroughly redesigned and updated, Motorcycle Trafic Crash Reconstruction examines the unique characteristics and special challenges that arise in collisions involving motorcycles and “Motorcycle Sliding Friction for Accident Investigation,” Institute for Motorcycle Safety: 10th International Motorcycle Conference, Cologne, Germany, 2014. Deceleration rate is an important variable when determining speed in the reconstruction of a motorcycle crash. Many studies have been performed to establish the drag factor of a downed motorcycle sliding across typical roadway surfaces. uybybulndddhxzqlffdaktktkwmqrcjrpshlnkuxsihpwkskafrkl
