SEARCH FOR RATIONAL TYRE PERFORMANCE PROCESS MODULE DRIVE WHEELS

Abstract

The dynamic model of technological mode with two rotating masses is considered: rim and bus of the driving wheel and speed mass of the technological module. Tire of driving wheel of t-nological module is characterised by coefficients of circumferential gesture-bone and damping. The procedure of optimization of the characteristics of the pneumatic tire of the driving wheel of the process module is presented taking into account the spectral density of the input load of the process module. Spectral density dispersion is taken as an index of efficiency of bus damping of driving wheels of technological-biological module. Resonance effect is determined by presence of marked extremes (peaks) at the curve of spectral density of oscillations of output process of technological module. The rational values of stiffness and damping coefficients of the bus of the driving wheels of the process module during MTA with TM of the process operation are taken as their values corresponding to the minimum value of the target function. Objective – determination of rational parameters of pneumatic tires of process module wheels by minimum value of target function. Method or methodology of work: the article uses methods of statistical dynamics and theory of random processes. Results: increased smoothness of tractor travel by damping of traction force oscillations due to elasticity of pneumatic tires of wheels and inertia of translational mass of process module. Field of result application: оobtained results are expedient to be used for improvement of tractor smooth motion and vibration protection of tractor driver.
