(Сибирский федеральный университет. Siberian Federal University, 2020-09)
The article deals with the connection with the complexity of the design of the car, the diversity of some of its properties and design features, as well as their various combinations and dependences on the operating conditions and type...
В связи со сложностью конструкции автомобиля, разнообразием рассмотрены некоторые его свойства и особенности, а также различные их сочетания, зависящие от условий эксплуатации и вида перевозок. Оценить автомобиль одним обобщающим показателем довольно трудно. Поэтому рекомендовано определять качество автомобиля комплексом наиболее показательных его эксплуатационных свойств: емкостью массы, скоростью движения, проходимостью, безопасностью и др....
