Researchers identify an increase in the mobility of equipment as one of these methods. It is assumed that an increase in mobility should have a positive effect on the protective properties of the object. The approaches proposed by the researchers are based on the use of protective acceleration and increased maneuverability of machines. As a result of these arguments, recommendations are given for accelerating the vehicle in order to move it away from the line of sight and the firing plane, and the value of the velocity that the vehicles should develop is indicated. However, these recommendations are given without considering performance abilities of a tracked vehicle. In this regard, there is a need to develop the method that makes it possible to link the traction capabilities of a tracked vehicle with its security.</p> <p><bold>AIM:</bold> Assessment of the impact of traction capabilities of a tracked vehicle on its protection, taking into account road and dirt conditions and design features.</p> <p><bold>METHODS:<italic> </italic></bold>The paper analyzes well-known approaches and recommendations for improving the protective properties of tracked vehicles. Based on the modern theory of motion, the possibilities of applying these approaches are considered, taking into account the limitations on grip properties and traction capabilities of tracked vehicles. The calculations were performed using the example of foreign samples of high-speed tracked vehicles, according to the technical specifications presented in open sources.</p> <p><bold>RESULTS:</bold> In this study, the method to determine the possibilities of using protective acceleration against the main unguided anti-tank weapons has been developed. The characteristics that a tracked vehicle must possess to achieve a protective acceleration have been determined and the limits within which they can be effective have been established. The factors preventing the possibility of increasing acceleration values are identified, and recommendations for their elimination are given.</p> <p><bold>CONCLUSION:</bold> The application of the developed method makes it possible to determine the required characteristics of tracked vehicles at the design stage, to assess the feasibility of using protective acceleration depending on the type of ammunition and firing range. Recommendations are given to improve the traction capabilities of promising models of machinery. The findings can be partially extended to wheeled vehicles.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Непрерывное развитие противотанковых средств поражения требует поиска новых способов повышения защитных свойств гусеничных машин. Одним из таких способов исследователи выделяют увеличение подвижности техники. Предполагается, что увеличение подвижности должно оказывать положительное влияние на защитные свойства объекта. Предложенные исследователями подходы основаны на применении защитного ускорения и повышения манёвренности машин. В результате этих доводов приводятся рекомендации по ускорению транспортного средства с целью его ухода с линии прицеливания и плоскости стрельбы, обозначается значение скорости, которую должны развивать транспортные средства. Однако эти рекомендации приведены без учёта возможности их реализации гусеничной машиной. В связи с этим возникает необходимость разработки методики, позволяющей связать тягово-динамические возможности гусеничной машины с её защищённостью.</p> <p><bold>Цель </bold>— оценка влияния тягово-динамических характеристик гусеничной машины на её защищённость, учитывая дорожногрунтовые условия и конструктивные особенности.</p> <p><bold>Методы. </bold>В работе проанализированы известные подходы и рекомендации для повышения защитных свойств гусеничных машин. На базе современной теории движения рассмотрены возможности применения данных подходов с учётом ограничений по сцепным свойствами и по тяговым возможностям гусеничной техники. Расчёты выполнены на примере зарубежных образцов быстроходных гусеничных машин, по техническим характеристикам, представленным в открытых источниках.</p> <p><bold>Результаты. </bold>В настоящей работе разработана методика, позволяющая определить возможности применения защитного ускорения от основных неуправляемых противотанковых средств поражения. Определены характеристики, которыми должна обладать гусеничная машина для совершения защитного ускорения, и установлены границы, в пределах которых они могут быть эффективными. Выявлены факторы, препятствующие возможности увеличения значений ускорения, и даны рекомендации для их нивелирования.</p> <p><bold>Заключение.</bold> Применение разработанной методики позволяет определить потребные характеристики гусеничных машин на стадии проектирования, оценить целесообразность применения защитного ускорения в зависимости от типа боеприпаса и дальности стрельбы. Даны рекомендации для улучшения тягово-динамических свойств перспективных образцов техники. Полученные выводы могут быть частично распространены и на колёсные машины.</p></trans-abstract><kwd-group xml:lang="en"><kwd>tracked vehicle</kwd><kwd>protection</kwd><kwd>acceleration</kwd><kwd>traction capabilities</kwd><kwd>power-to-weight ratio</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гусеничная машина</kwd><kwd>защищённость</kwd><kwd>ускорение</kwd><kwd>тягово-динамические качества</kwd><kwd>энерговооружённость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Aleshin IN, Andryushchenko MS, Yevdokimov VI, et al.
