“…Based on the simulation results of the design, the vehicle continued moving after impact with the concrete barrier. Borovinšek et al (2007) conducted large-scale crash tests using a heavy truck to calculate side deflections for road safety barriers. The simulation of the crash test using the LS-DYNA program was conducted under the same conditions following the European Standard.…”

“…Laboratory models have been used in other studies to test impact loads, Gabauer et al (2010). Theoretical finite element method (FEM) is used by several software, in particular LS-DYNA and ANSYS programs, to simulate concrete barriers and vehicles, Itoh et al (2007a); Se-Jin et al (2008); Consolazio et al (2003); Borovinšek et al (2007); Zhong et al (2009) ;Wang et al (2013). One of the most critical road transportation problems is the protection of road users.…”

Concrete barriers prevent vehicles from entering the opposite lane and going off the road. An important factor in the design of concrete barriers is impact load, which a vehicle exerts upon collision with a concrete barrier. This study suggests that a height of 813 mm, a base width of 600 mm, and a top width of 240 mm are optimum dimensions for a concrete barrier. These dimensions ensure the stability of concrete barriers during vehicle collisions. An analytical and experimental model is used to analyze the concrete barrier design. The LS-DYNA software is utilized to create the analytical models because it can effectively simulate vehicle impact on concrete barriers. Field tests are conducted with a vehicle, whereas laboratory tests are conducted with machines that simulate collisions. Full-scale tests allow the actual simulation of vehicle collisions with concrete barriers. In the vehicle tests, a collision angle of 25°, collision speeds of 100 km per hour, and a vehicle weighing more than 2 t are considered in the reviewed studies. Laboratory tests are performed to test bridge concrete barriers in static condition.

“…Apart from the technical aspects of FEM approach (like hardware availability or time-consuming simulation), the biggest challenge is to correctly select material properties of a colliding vehicle and its surroundings [1,2]. Therefore, there are observable trends to decompose complex mesh models into arrangements which are less composite [3][4][5][6][7]. FEM model is capable of representing geometry and material details of a structure.…”

Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this work, a brief overview of different vehicle crash modeling methodologies is proposed. The acceleration of a colliding vehicle is measured in its center of gravity-this crash pulse contains detailed information about vehicle behavior throughout a collision. A virtual model of a collision scenario is established in order to provide an additional data set further used to evaluate a suggested approach. Three different approaches are discussed here: lumped parameter modeling of viscoelastic systems, data-based approach taking advantage of neural networks and autoregressive models and wavelet-based method of signal reconstruction. The comparative analysis between each method's outcomes is performed and reliability of the proposed methodologies and tools is evaluated.

This paper presents application of physical models composed of springs, dampers and masses joined together in various arrangements to simulation of a real car collision with a rigid pole. Equations of motion of those systems are being established and subsequently solutions to obtained differential equations are formulated. We start with a general model consisting of two masses, two springs, and two dampers, and illustrate its application to represent fore-frame and aft-frame of a vehicle. Hybrid models, as being particular cases of two mass-spring-damper model, are elaborated afterwards and their application to predict results of real collision is shown. Models' parameters are obtained by fitting their response equations to the real vehicle's crush coming from the acceleration measurement analysis. For full-scale experiment and created models we perform both: kinematic and energy responses comparative analysis.
