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

This paper describes the development and application of an autonomous register and measurement system (ARMS), and the application of microelectromechanical systems (MEMS) accelerometers to the assessment of blast threat to armored vehicle crews. Taking measurements with reference to an explosion is one of the principal issues in the protection of crews of special vehicles. The proposed ARMS reduces research costs and contributes to the development of an autonomous, wireless test stand, applicable in various research areas and industry. The ARMS performs data acquisition with simultaneous measurement in multiple channels. The maximum sampling rate is 100 kHz and the sensor range is ±500 g. This solution is an alternative to cable systems, which have a high energy demand. The functionality of the developed autonomous measuring system is demonstrated experimentally. The paper concludes with a field study of the proposed system and the application of MEMS accelerometers via a mine blast test of a military vehicle at level 4 of STANAG 4569.

ALGORITHM FOR EVALUATING MILITARY TECHNICAL EFFICIENCY OF USING MILITARY VEHICLE EQUIPMENT BY PARTS AND DIVISIONS OF THE NATIONAL GUARD OF UKRAINE IN THE COURSE OF BATTLE ACTIONS (OPERATIONS)

The article argues the relevance of determining the indicator of military-technical efficiency of the use of military automobile equipment by units and subunits of the National Guard of Ukraine when performing battle actions (operations). Currently, special indicators are used to assess the state of military automotive equipment, which are a numerical expression of the gauges or their relationship. Existing methods of planning technical support, methods for predicting the quantitative assessment of the military-technical efficiency indicator of the use of military automotive equipment during hostilities need further improvement. The article proposes to use a comprehensive indicator, a generalized coefficient of military-technical efficiency of using military automobile equipment during combat actions (operations), as an indicator of military-technical efficiency of using military automobile equipment in combat conditions, and to determine directions for increasing the efficiency of using military equipment. Keywords: automotive technical support; military automotive equipment; military-technical efficiency of using military automobile equipment; performance indicators; technical readiness coefficient; machine use efficiency during battle actions (operations)

The Basics of Developing an Alternative Concept for Commercial and Military Vehicle Operation (Random Strategy)

The efficiency of commercial automobiles and wheeled military vehicles mainly depends on the choice of maintenance (M) and current repair (CR) concept. In the paper the difficulties of adapting the (M) and (CR) planning strategies to the structural characteristics of modern transport facilities are pointed out. The advantages of using the (M) and (CR) random strategy for transport facilities based on the stochastic nature of failures and malfunctions are substantiated. Considering the failures and malfunctions as random values and identifying the patterns of their distribution based on γ percentage resources, it is proposed to develop a list of regulated maintenance and repair work, periodicity and labor intensity based on a random strategy, which will increase the efficiency of preserving the technical resource of the rolling stock throughout the entire life cycle of the vehicle.

A detailed approach to autonomous vehicle control through Ros and Pixhawk controllers

A Polaris MRZR military utility vehicle was used as a testing platform to develop a novel, low cost yet feature-rich, approach to adding remote operation and autonomous driving capability to a military vehicle. The main concept of operation adapts steering and throttle output from a low cost commercially available Pixhawk autopilot controller and translates the signal into the necessary inputs for the Robot Operating System (ROS) based drive by wire system integrated into the MRZR. With minimal modification these enhancements could be applied to any vehicle with similar ROS integration. This paper details the methods and testing approach used to develop this autonomous driving capability.
