Research of the dynamics of the all-wheel-drive tractor-transport machine

Abstract

The study results of the dynamic and traction-energy performance of an all-wheel drive traction-transport vehicle have been presented. A diagram of a dynamic model of the transmission of an all-wheel drive traction-transport vehicle and a system for calculating the transmission dynamics in the Cauchy form has been compiled. The method makes it possible to determine the distribution of the coil fluids of the transmission elements of a traction-transport vehicle, the distribution of torque moments, and the distribution of additional traction forces on the wheels per hour. The method allows you to determine the optimal transmission parameters, differential design, and transmission numbers to improve the traction and fuel-economic performance of the machine. It has been established that the speed of the front wheels of a traction and transport vehicle is 1.29 rad/s, 1.27 rad/s, and the speed of the rear wheels is 1.24 rad/s, 1.25 rad/s, which should be carried out until kinematic instability and additional energy consumption. The torque values of the front drive wheels are 6972 N m, and the rear drive wheels are 4622 N m. The additional traction forces on the car's front wheels are 5478 N after the car's acceleration is completed, and on the rear wheels, they are 347 3 N. To verify the adequacy of the method for assessing the dynamics of an all-wheel drive transmission, Wheeled traction, and transport vehicles have been developed to simulate the dynamics and energy systems of mobile vehicles—experimental research of the machine on the butt of an all-wheel drive wheeled tractor with an articulated frame. The difference between the values of the heel fluids of the wheel wraps, theoretically and experimentally, is 2%, which indicates a significant loss of the heel fluids by the wheel dynamics sensors. A comprehensive method for assessing the transmission dynamics of an all-wheel drive traction and transport vehicle must be considered adequate. The robotic method can be used to assess the dynamics of wheeled vehicles in motor vehicles. Keywords: cutting speed, torque, traction force, transmission, traction, and transport vehicle.
