摘要：
In the development of heavy-duty and motorization of multi-axle special vehicles，power transmission performance is the guarantee of their rapid maneuvering combat ability and a manifestation of wartime survivability. The internal resistance loss of the transmission system will reduce the power transmission efficiency and directly affect the power performance, among which the mechanical friction resistance loss is the main loss of the transmission system. Focusing on the mechanical friction resistance loss characteristics and transmission efficiency research methods of the transmission system, this paper firstly analyzes the structural particularity of the multi-axle special vehicle transmission system and shows the importance of transmission efficiency to the transmission system performance. Secondly, the formation mechanism and main influencing factors of four main types of mechanical friction resistance loss are analyzed，namely gear meshing power loss, bearing friction power loss, oil seal power loss and transmission shaft power loss, which shows the relationship between transmission efficiency, structural parameters of components, and operating conditions, and provide an analytical basis for the characterization of transmission system performance. Then, the research core and difficulties of transmission system efficiency are summarized from three aspects: theoretical numerical study, simulation study and experimental demonstration study, which provides guidance for the optimal design and condition monitoring of transmission components, optimal matching and performance evaluation of transmission systems. Finally, the prospect of the current research depth of transmission efficiency characteristics is expounded, and it is considered that multi-factor coupling analysis, uncertainty analysis, dynamic characteristic analysis of power loss, and comprehensive transmission efficiency analysis based on vehicle driving conditions have more engineering application value. © 2023 Chinese Vibration Engineering Society.
