“…To improve modelling efficiency, both the vehicle motion model and the quasi-static fence model outlined above involve only those collapse mechanisms which are assumed to have a primary effect on the predicted vehicle and fence response.

A computer simulation has been developed at The University of Sheffield that predicts the impact performance of roadway wire rope safety fences. Effective use of this simulation for design, or other purposes, requires it to be validated by showing that the predicted vehicle motion and fence response closely represent that of the real system. Two distinct validation studies are described in the current paper. The first compares the major results of eight impact tests undertaken at the UK Motor Industry Research Association and a further four impact tests undertaken at the Swedish Road and Transport Research Institute with the simulation predictions. The close prediction of the test results validates the use of the simulation as a design tool for a range of fence designs and impact conditions. The second validation study compares, in detail, the test results and simulation prediction for a single test. This suggests that, if required, results may be improved further by considering suspension effects in the vehicle model, and by a better understanding of frictional effects at the rope-post and the rope-vehicle contacts.

“…Simulationof cable barrier crash dynamics was first published in 2001[4], This study investigated a roadside safety wire rope fence and the algorithm developed was based on the analysis of a large amount of roadside safety cable barrier crash test data. The algorithm was validated with crash test data involving small vehicles with acute angle of impact.…”

Perimeter security cable barriers are widely used by various agencies all over the world to defeat threat vehicle penetration. New barrier designs require crash test validation prior to implementation. Full-scale vehicular crash tests are costly, whereas designs via finite element simulations are time consuming and require specialized skills. Based on full-scale crash tests, an innovative and simple algorithm has been developed to model the progressive failure of security cable barriers. A multi-body approach based on the first principles of physics was developed to substantially reduce computer runtime. The solution algorithm uses a large number of small time steps. Nonlinear vehicle and cable forces and deformations are calculated based on compatibility conditions. This methodology has been validated against three full-scale crash tests. This cable barrier model, displaying simulation results graphically in a time series, provides realistic response parameters of a security cable barrier design in less than 10 minutes of runtime with reasonable accuracy.
