AbstractA hollow auxetic cylinder lattice structure (HCLS) is proposed with tapered three-dimensional reentrant cells (TRCs) and connecting plates. The compressive performance of HCLSs studied by finite element analysis (FEA) compression test. show excellent energy absorption negative Poisson's ratio properties as well unique rotational deformation mode during compression. influences structural parameters on the HCLS are further studied. values maximum rotation angle H-hs2.0 minimum (MPR)...
The problem of injury protection for pedestrian is a research hot spot in traffic safety, and simulations are important tools. In the process design simulation experiments, gaits become more important. Hence three gait serials (walking, running emergency) were found through observing reconstructing 150 vehicle-pedestrian collision videos. Further studies had that speed different among there significant difference between Pedestrian Speed Before Collision (PSBC) at Instant (PSIC) same serial;...
Pedestrians suffer significant injuries from ground contact, but attempts to reduce them have been limited. A recent study using multi-body simulations showed contact injury may be improved by controlling vehicle braking. The aim of the is assesses whether controlled braking would beneficial in real-world collisions. PC-Crash was used reconstruct 150 freely available pedestrian video Pairwise comparison actual versus then performed for each case. Pedestrian evaluation metrics included head...
To predict the classification of pedestrian landing mechanism in pedestrian-vehicle collisions, 1303 reconstructed real collision cases were selected, and relevant data from before, during, after collisions extracted. A total sets with eight parameters obtained via significance analysis, correlation collinearity analysis. Then, Backpropagation Neural Network (BPNN), Genetic Algorithm (GA) optimized BPNN (GA-BPNN), Principal Component Analysis (PCA) (PCA-BPNN), (PCA-GA-BPNN) used to construct...
Cyclists are vulnerable road users and often suffer head-neck injuries in car-cyclist accidents. Wearing a helmet is currently the most prevalent protection method against such injuries. Today, there an ongoing debate about ability of helmets to protect cyclists' from injury. In current study, we numerically reconstructed five real-world impact accidents, incorporating previously developed finite element models four cyclist evaluate their protective performances. We made comparative injury...
The knowledge about the injury source and correlation of riders in car-electric bicycle accident will be helpful cross validation traces vehicle safety design. In order to know more information such kind knowledge, 57 true accidents were reconstructed by PC-Crash then data on collected directly from cases. These validated some existing research results firstly, 4 abnormal cases deleted according statistical method. Finally, conclusions can obtained remaining 53 Direct injuries head right leg...
In order to access the maximum benefits of controlled vehicle braking in reducing ground related injury, based on a basic simulation test sample, which include 24 simulations with three velocities, four pedestrian sizes and two gaits, 10176 were conducted by Madymo. After comparative study, we found that caused injury will not increase if is starting reduce at time head first contact WIC/HIC can be maximally reduced 88.9% 75.6% respectively controlling efficiently. Through further analysis...
As the use of electric self-balancing scooters (ESSs) increases, so does number related traffic accidents. Because special control method, mechanical structure and driving posture, ESSs are prone to various single-vehicle accidents, such as collisions with fixed obstacles falls due failures. In ESS accident scenarios, rider's head injury is most frequent type. this study, several typical single-ESS scenarios reconstructed via computational methods, risk riders' head/brain assessed in depth...
