“…Deyerl and Cheng [5] demonstrated the use of EDSMAC4 to model the crashes reported by Adamson et al In order to match the automotive damage profiles, the authors had to increase the stiffness coefficients by up to 300% over the nominal A and B value at different areas of the target vehicles. Warner [6] reported on the local effect of vehicle stiffness variations, as related to narrow object (pole) impacts, finding that front axle and A-pillar locations sustained roughly half the crush when compared to centerof-gravity and B-pillar locations for the same amount of energy dissipated. This is consistent with Deyerl's observations regarding car stiffness during motorcycle impacts.…”

E leven instrumented crash tests were performed as part of the 2016 World Reconstruction Exposition (WREX2016), using seven Harley-Davidson motorcycles and three automobiles. For all tests, the automobile was stationary while the motorcycle was delivered into the vehicle, while upright with tires rolling, at varying speeds. Seven tests were performed at speeds between 30 and 46 mph while four low-speed tests were performed to establish the onset of permanent motorcycle deformation. Data from these tests, and other published testing, was analyzed using available models to determine their accuracy when predicting the impact speed of Harley-Davidson motorcycles. The most accurate model was the Modified Eubanks set of equations introduced in 2009, producing errors with an average of 0.4 mph and a standard deviation (SD) of 4.8 mph. An updated set of Eubanks-style equations were developed adding data published since 2009, and advancing from two equations (pillars/axles and doors/fenders) to four equations (axles, pillars/bumpers, doors, and fenders). When applied to the subject tests, the newly developed set of equations produced an average error of 3.5 mph (SD = 4.3 mph). With respect to all available data (N = 99), the equations produced an average error of 0.1 mph and a standard deviation of 5.8 mph. The errors were also analyzed for each of the four equations developed here, and confidence intervals offered. This research, which represents the first detailed analysis of Harley-Davidson motorcycles' collision response, indicates they behave in a manner similar to previously tested motorcycles. Further, the equations developed and presented here give accident investigators a refined method for estimating the impact speed of an upright motorcycle, Harley-Davidson or otherwise, having struck an automobile with its front tire.

Pole side impact is one of the most common types of vehicle collisions. The pole side impact at high vehicle speed induces not only local collapse but also bending of the vehicle body. However, the estimation method of the vehicle speed with consideration of the bending has not been established yet. In the present study, the deformation of the vehicle body at the pole side impact experiment with impact speed of 80 km/h was investigated. The results revealed that the collapse deformation first occurred and then the bending deformation followed. In order to understand the deformation of the vehicle at high-speed pole side impact, lateral local compression test and three-point bending test of rectangular steel tubes were performed. It was found that the deformation of the tube was similar to that of the vehicle at the pole side impact experiment, when the specimen was subjected to the sequential test of lateral local compression and three-point bending. The change in the energy absorbed by the deformation of tube in the sequential test was also found to be similar to that in the vehicle experiment. These similarities are useful to investigate the vehicle collision speed at high-speed pole side impact based on the deformation and the absorbed energy of rectangular metal tubes. : Automobile, Traffic accident investigation, Vehicle collision, Pole side impact, Material testing, Lateral local compression, Three-point bending, Absorbed energy *1 正員，岡山県警察本部刑事部科学捜査研究所(〒700-0816 岡山県岡山市北区富田町 1-3-2) *2 正員，岡山理科大学工学部機械システム工学科(〒700-0005 岡山県岡山市北区理大町 1-1) *3 正員，岡山大学大学院自然科学研究科(〒700-8530 岡山県岡山市北区津島中 3-1-1) *4 正員，科学警察研究所交通科学部(〒277-0882 千葉県柏市柏の葉 6-3-1
