Minimisation of the explosion shock wave load onto the occupants inside the vehicle during trinitrotoluene charge blast

Abstract

The aim of this study was to elaborate identification method of crew overload as a result of trinitrotoluene charge explosion under the military wheeled vehicle. During the study, an experimental military ground research was carried out. The aim of this research was to verify the mine blast resistance of the prototype wheeled vehicle according to STANG 4569 as well as the anti-explosive seat. Within the work, the original methodology was elaborated along with a prototype research statement. This article presents some results of the experimental research, thanks to which there is a possibility to estimate the crew's lives being endangered in an explosion through the measurement of acceleration as well as the pressure on the chest, head and internal organs. On the basis of our acceleration results, both effectiveness and infallibility of crew protective elements along with a blast mitigation seat were verified.

A Numerical Analysis of the Working Machine Tyre Inflation Process to Ensure Operator Safety

“…The main area of flow is marked with a blue arrow, and the red dashed arrow shows where the flow was tangential to the tyre surface. This publication focuses on a case in which a safety cage was not used, and the overinflation of a large tyre to 1.1 MPa can lead to fatal head injuries [17,18].…”

“…In Figure 3, the example safety cage manufactured by RLM Distributing is shown beside a computer-aided 3D model created by the authors for the LENA Wilkow company. This publication focuses on a case in which a safety cage was not used, and the overinflation of a large tyre to 1.1 MPa can lead to fatal head injuries [17,18].…”

The Application of Microelectromechanical Systems (MEMS) Accelerometers to the Assessment of Blast Threat to Armored Vehicle Crew

“…The protection of crews of military vehicles became a pre-eminent issue in NATO countries with the emergence of the first analyses and consequences of military operations in Iraq and Afghanistan. Based on the statistics of contemporary military operations or stabilization missions, it is estimated that in approximately 60% of cases, mines and improvised explosive devices (IEDs) are the principal cause of death or serious injury to soldiers [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ].…”

“…Standard criteria for assessing the risk to life of the crew apply to those parts of the body classified as most vulnerable to injuries: lower limbs, thoracic-lumbar spine, cervical spine and head, and chest and internal organs [ 4 ]. Analysis of data from the wars in Afganistan and Iraq shows that soldier mortality was most frequently associated with brain injury, and the most frequently injured part of the body were the lower limbs, resulting in amputation or fracture [ 4 , 5 , 8 , 9 , 10 ].…”

Identification of the shockwave effect onto Explosive Ordnance Disposal (EOD) personnel during controlled airblast of TNT charge

“…The proper processing of the recorded signals is also an important issue (Krzystała et al, 2016). NATO AEP-55 Vol.…”
