“…Different influence of the angles on the final calculation is demonstrated, for example, by a contribution in the proceedings. [9] Using the input data from Tables 3 and 4, the required sizes of inertia forces are calculated, which must correspond to the permissible load-carrying capacity-traction force (LC) of the used fastening straps. The inertia forces are calculated for the x and y axes, for each of the three fastening methods and for two different sizes of friction factor (for µt = 0.3 and model value for µw = 0.6).…”

The paper identifies possible ways of fastening military vehicles on rail freight wagons using textile fastening straps and then compares particular methods. The comparison includes, besides used methods—diagonal lashing and V-shape diagonal lashing, the previously used method of lashing—slope lashing, which is currently not allowed to use. To calculate the inertia forces affecting the cargo, respectively the fastening straps, appropriate methods in accordance with EN 12195–1 have been chosen. In the discussion part, recommendations in relation to the fastening of military vehicles on rail freight wagons are introduced.

Cargo security during road transportation particularly presents a current topic in the context of transport safety. One of the key factors influencing the magnitude of impact (acceleration coefficients) during transportation is the quality of the road networks. Acceleration coefficient values directly affect the rate of inertia forces influencing the cargo. Given that the inertia force magnitudes (acceleration coefficients) are not known prior to commencing the actual transport, acceleration coefficient values known from regulations or otherwise (for example, empirically) certain established values must be used. Values of acceleration coefficients were established in EN 12195-1, a regulation typically used within the European Union. This chapter covers the approaches of this standard and provides comparison of acceleration coefficients established through regulations with those measured. Data (coefficient acceleration) from both highway transport and unpaved roads (in off-road conditions) were measured and statistically processed for comparison purposes. The transportation model presented subsequently demonstrates differences in the magnitude of inertia forces using three sets of dataacceleration coefficients obtained from the standard, from highway transport, and from off-road transport. At the same time, these secured cargoes were set into an insufficient context, where unsuitable or insufficient security of the cargo represents one of the significant risks in the occurrence of an accident.

This article presents the results of a study of the braking process in terms of assessing the longitudinal loading condition of transported cargo. The existing methods of securing cargo do not take into consideration the type of vehicle used to transport the cargo. This may result in cargo not being transported in compliance with the principles of proper cargo protection. This paper discusses the differences in maximum deceleration values achieved by different types of vehicles that are structurally suitable for freight transport. As a result of these differences in deceleration values, the values of forces acting on the transported cargo are also different. This paper presents and analyses the results of road tests that entailed the heavy braking of two vehicles structurally suitable for freight transport. One of them was a delivery vehicle, while the other was a semi-trailer truck. The experiment was carried out in six measurement series. Four of them were performed on an asphalt pavement, while the other two on a concrete pavement. One series included ten brake tests. Deceleration values registered during the tests were later used to determine the values of coefficient Cx, which were then compared with standardised values. It has been shown that failure to take into account in the selection process of cargo securing equipment, vehicle category, and type and condition of the pavement can result in cargo displacement and even traffic incidents.
