摘要
The review of performance and energy effectiveness of transportations reveals the lack of the squared delivery speed in their structure. The need to attract the squared speed as the major factor in forming the assessment of the energy intensity of the object motion and the medium resistance is noted. The author's approach to forming assessments of the transport energy intensity based on the use of Bartini's LT-systematization and the entity of Transfer with the measurement unit of Tran is considered. The energy effectiveness factor of cargo movement is represented in the form of the ratio between the inevitable dissipation of the cargo movement energy and costs of the energy supply of transportation, incurred by the automotive transport system. As an example, the calculation of the transportation by KamAZ-5320 automotive vehicle is carried out. The value of the energy effectiveness of transportation with the speed of 60 km/h, calculated with the use of Transfer, amounted to η = 11.6 %. This allowed assessing the technological paradigm of the modern automotive transport as very far from the perfection.
