Simulation And Study On Driven Parameters Matching Of Vibration Roller With Double-wheel Drive

The research on driven parameters matching of vibration roller with double-wheel drive is based on the traction performance for years. This article studies it from the angles of traction performance and evenness.The mechanism of vibratory compacting was analyzed and improved, five degrees of freedom of dynamics former were built in the vibratory roller with dual steel wheels, the main factors for influences of vibratory compacting were summed-up and analyzed through compacting material, compacting machinery and construction craft, and compared and explained the compacting capabilities of vibration roller with double-wheel drive and vibration roller with single-wheel drive.Terramechanics of vibration roller with double-wheel drive was analyzed from two aspects as dynamic performance and adhesion performance. The research learned the distribution ratio in the front & rear wheels of system with double-wheel drive and parameters matching for motor as well as the change of traction parameters during this process, MATLAB software was applied for the imitation of change curve and the analysis and illustration of the simulations.The wheel-soil interaction of vibration roller and mechanical property of its wheel were analyzed and reported, the front & rear wheels distribution ratio, parameters matching for motor and the working principle of hydraulic driving system were given in the research according to the traction performance and evenness. The vibration rollers with double-wheel drive have the same front & rear wheels distribution ratio and parameters of motor, the drive system is an independent tandem type system, the front & rear wheels distribution ratio in vibration roller with single-wheel drive is 2:1. The parameters of motor are different and the drive system is an parallel system.
