ABSTRACT
Vibratory compaction is an efficient machine, widely used in the construction of road construction. The development of domestic and foreign research into the history compacting machinery, take compaction and compaction machinery ethnology trends and latest developments. 12T Roller products to provide the basis for positioning.
China road roller, the overall technological level compared with foreign countries there are still gaps, mainly in: Model insufficiency, heavy and extra heavy-duty roller number and variety of production is still small, specialized compaction equipment, lack of comprehensive technical and economic indicators and automatic control is still lower than the advanced level.
In this paper, theoretical analysis and calculation based on the overall completion of 12T vibratory roller and hydraulic systems, vibration wheel assembly, shock absorber system and other major components of the design, plan, structure and design methods for innovation: all-hydraulic transmission scheme, by three independent hydraulic circuit of walking, vibration and steering the three basic functions, and compared the compaction effect of mechanical drive, climbing ability, quality and distribution, operation control and the overall layout has more advantages. Turn structure using the program articulated frame waist to change direction, turning radius, mobility, front and rear tracks overlap, low center of gravity, the driver broad field of vision. Hydraulic brake system with static brake, multi-disc friction brake and electro-hydraulic operation, while braking, braking effect is good. Eccentric shaft vibration exciter designed to increase the structure of two active forms of eccentric, eccentric block is placed in cylindrical cabinets filled with silicone oil, both achieved double amplitude of the vibration frequency function, but also avoids the agitation and lubricants The impact is strong. Rubber shock absorber damping system is to use a more simplified single degree of freedom vibration model is derived for maximum vibration damping effect of the total system when the dynamic stiffness, as the basis for the design of rubber shock absorber, and the roller was stability analysis.
KEY WORDS: vibratory roller, design, frame, hydraulic, vibration force, vibration
