To reduce tyre/road noise, the concept of poroelastic road surfaces (PERS) was invented. PERS is a road surface material that is porous, and at the same time, it is flexible because of the substantial amount of rubber granulate content (from 20% to 85%). The rubber and stone particles are bound by polyurethane resin instead of bitumen. It was feared that in case of fire, because of the high content of rubber and polyurethane, there may be considerable emission of potentially hazardous substances (such as hydrogen cyanide) from burning PERS. Tests performed by the Technical University of Gdansk show that the emission of toxic gases is rather small and that the surface does not promote car fire, even when soaked with fuel. Car fire with fuel spill on PERS is less dangerous for passengers than car fire on dense road surface as the fire is spreading much slower. The article presents results of laboratory and road experiments carried out within FP7 'PERSUADE'. Copyright © 2014 John Wiley & Sons, Ltd.

One of the priority for military force is modern land platform development. Similar goal is in European Defense Agency, there plan to future fighting vehicles develop. The paper present simulation research of future wheeled Armored Fighting Vehicles. The paper included original simulation model for AFV taking in consideration EBS and ABS systems and simulation test result for typical road test also present experimental verification. Experimental research studies of vehicles are of high cognitive importance. However, they are expensive, time-consuming and sometimes dangerous, especially when they refer to edge safety parameters of a vehicle motion. Their scope can be limited if researchers conducting the studies have at their disposal a mathematical model of the vehicle motion and dynamics and a simulation program allowing for carrying out research in "virtual space." A start-up of the simulation process requires gathering a relevant and require amount of data. If the simulation research studies that have been conducted are used for experimental verification, it is essential to obtain them to carry out a "package" of a series of experiments and a detailed design documentation analysis.

The paper presents an instrumented vehicle that was equipped with measuring systems to perform complete dynamics tests, especially in off-road conditions. The equipment consists of four wheel dynamometers, a steering robot, and a differential GPS system together with an inertial platform, a non-contact vehicle speed sensor, and an on-board computer with software to control the devices and collect experimental data. The four wheel dynamometers measure six elements; based on strain gage force transducers, it measures three orthogonal forces and three moments. The steering robot can control the steering wheel of the vehicle at a variety of excitation modes; it can carry out typical vehicle dynamics tests (ISO 7401, ISO 4138, ISO/TR3888, etc.) as well as custom engineered tests at a wide range of setting parameters (steer angle rate up to 1600 deg/s). The differential GPS system gives true time vehicle kinematics data (velocities, accelerations, angles, etc.) at 10-ns sample rate and 20-mm accuracy. The base vehicle, a Suzuki Vitara 4 × 4, required no special modifications or changes to install the measuring equipment. The paper also describes typical tests performed with the use of the instrumented vehicle together with sample results. © 2011 ISTVS. Published by Elsevier Ltd. All rights reserved.
