Abstract Increasingly demanding performance standards and operating requirements are driving the growing interest on multi-field coupling technologies in gear transmission systems. Optimized factors of gear multi-field coupling technology are necessary to meet the high-speed and heavy-load capacity requirements of the gear transmission system and solve the problem of gear failure under highspeed and heavy-load working conditions. Numerous theoretical and experimental studies have been dedicated to gear multi-field coupling, especially on gear accurate modeling method and multi-field coupling simulation analysis method. The accurate model of the gear can provide a model basis for the thermal–fluid–solid multi-field coupled numerical simulation. The choice of gear multifield coupling simulation method is the way to realize gear multi-field coupling simulation. In order to compile and categorize key investigations in an expansive field with substantial recent research, this work reviews factors of gear multi-field coupling simulation papers with focus on gear accurate modeling method and multi-field coupling simulation analysis method. Keywords Multi-field coupling simulation Accurate modeling Gear failure Gear transmission

Introduction Gear transmission is a widely used transmission form [1, 2]. In recent years, the machinery industry has become increasingly demanding on the reliability, efficiency and carrying capacity of gear transmissions, and gear transmissions are developing in the direction of high-speed and heavy-load. Under high-speed and heavy-load working conditions, the gear meshing friction will generate a lot of heat. The instantaneous high temperature generated on the meshing surface will cause the gear gluing, tooth breaking [3] and other failures. At the same time, it will change the physical parameters of the lubricating oil, reduce its lubrication and cooling performance and cause a series of gear failure problems [4–7]. Ghazali et al. [8] classified the faults displayed by polymer gear, which can be attributed to broken teeth, deformation, material removal and surface fatigue. In addition to these gear faults, Bian et al. [9] determined that the fault form of the gear was electrical erosion by observing the similarity of tooth surface morphology of the two groups of gears and calculating the contact strength and anti scuffing ability of the gears. Different failure problems of high-speed and heavy-load gears pose great harm to gear transmission. Therefore, through the
