Opis:: On the work one described chosen problems concerning of threats of the crew of the armoured personnel carrier with dynamic loads during crushing the obstacle. One paid attention on the lack of regulations regulative this problems. One described the general construction, and also worked out model of the armoured personnel carrier and crashed object. To the modelling one used the software LS-DYNA, using the method of finite elements. One gave also conditions for carrying out the numeric research. On the work one placed example results of numerical tests, deformations and stresses in the hull of the vehicle and in the crashed gate. One placed also example-courses of the speed and accelerations of chosen elements of the vehicle and people inside. On the basis on received results of simulation research one evidenced high level threats of the crews, liable to be effective with serious offences, particularly of the head and the spine. One qualified also directions and the range of further works targeting the improvement of the safety of the crew, in this taking into account the use of investigative dummy man. To further research one proposed models of dummy man Hybrid III, which for the necessity of taking in to consideration of additional elements of the equipment of soldiers (e.g. the helmet, the weapon, the bullet-proof vest) must be however properly modified. One pointed also on the necessity of working out the additional protective devices and also formulate the methodology of the experimental research.

Opis:: The work describes chosen problem connected with using of armoured personnel carriers (APC) in the frame of military operations. The soldiers inside the APC are exposed to dynamic loads and shock which are, among other things, an effect of collision with other vehicle or terrain obstacles. In military vehicles, which design is based on a rigid frame or integral body, there is no technical solution to mitigate the effects of a crash. The only applicable means of protection against the effects of collisions are lap belts and helmet designed to protect the head. Preliminary research shows that this kind of equipment is not sufficient. In the work an assessment of the influence of chosen solutions of safety belts and helmets on dynamic loads of carrier’s crew during collision with a rigid obstacle are presented. In simulation researches the HYBRID III dummies models have been used and calculations were carried out in LS-DYNA system. The work shows the numeric test results. Behaviour of the dummies during the impact on both the driver and crew member were presented. To assess a risk of injury standard indicators of crash test were used, including: maximum value of the head acceleration and the maximum values of the forces and moments in the neck. The distributions of these parameters were presented. The assessment of applied passive safety systems was made from the point of view of treat to soldiers inside a carrier.

Opis:: The work describes chosen problem connected with using of armoured personnel carriers (APC) in the frame of stabilisation and peacekeeping mission. The new type of tasks appears: ramming obstacles such as fences, entry gates, light engineering obstacles and also pushing other vehicles aside the road in order to obtain trafficability. The main threat in such situation is a risk of serious injury of soldiers inside vehicle. The lack of a crumple zone increases a value of acceleration acting on the crew. In the work models of driver and crew member seats used in the APC were showed. To the tests a Hybrid III 50th male dummy model in a seated position were used, which is a good representation of the average population of men. To the modelling LS-DYNA software was applied. The work shows the numeric test results. Behaviour of the dummies during the impact on both the driver and crew member were presented. To assess a risk of injury standard indicators of crash test were used, including: maximum value of the head acceleration, the criterion HIC and the maximum values of the forces and moments in the neck. The distributions of these parameters were presented. Results of simulation indicated that velocity and location of dummies has large influence on levels of dynamic loads. To further research is proposed to take into consideration models of dummy with additional equipment of soldiers (e.g. a helmet, a weapon, a bullet-proof jacket).

Opis:: The paper presents problems related to dynamic loads of armoured personnel carriers design as well as soldiers located inside them. During tactical operation, there is often the need for ramming other vehicles or terrain obstacles in order to provide road possibility. The lack in armoured vehicles, commonly used in cars crumple zones, will result in large values of accelerations. This can cause significant risk to the crews of vehicles. In order to assess the exposure of soldiers while overcoming terrain and engineering obstacles experimental studies were performed covering a carrier’s collision with a rigid barrier and ramming of all-terrain vehicle. In the paper the research conditions and used measurement equipment were described. A four-wheel SKOT personnel carrier and Tarpan Honker car, out of service, was used for the tests. The tests were carried out within the area of the Military Institute for Armoured and Automotive Technology in Sulejówek. During crash tests, anthropomorphic measurement equipment – Hybrid III 50th Male Dummy type – was used for recording the values of loads affecting the soldiers. The article presents some results of experimental studies. The values of the carrier’s body accelerations in driver’s and landing troop compartment were compared as well as dynamic loads of test dummies. The results obtained during vehicle ramming prove that these types of actions do not cause serious threats for the members of the carrier crew.

Opis:: The results of the experimental research on the influence of the special vehicle movement conditions on the body shell and the vehicle crew dynamic load will be presented in the paper. ROSOMAK Wheeled Armoured Personnel Carrier (Wheeled APC), the basic version, was the subject of the research. The research work was aimed at analysis of the dynamic loads resulting from the deterministic inputs and driving on the selected types of surfaces generating random kinematic inputs. The personnel carrier service conditions, measuring apparatus, and testing methods will be described. The vertical accelerations of the selected points of the vehicle, and deflection of the prime and second suspension of the vehicle left side were measured. The time and the acceleration RMS value spectrum charts for the selected implementations will be presented. The cumulative statistics will be shown in the form of a table. The conclusions regarding the influence of the road surface on the personnel carrier driver's working comfort will be formulated. The assessment of the suspension quality will be included in the conclusions. Driving on the smooth surface is comfortable. However, the road surface worsening causes decreased proficiency sense until the exposure limit boundary is reached when the vehicle drives on a poor quality cobble road with 50 km/h speed. The vehicle basic version is not fitted with the seats for assault troops, therefore the influence of the road irregularities on the centre of mass of the body shell, and the driver's and commander's seats were determined. It is recommended to make further tests on the personnel carrier combat and special versions.
