Test method of slippage rate of tractor

Abstract

The invention provides a test method of slippage rate of a tractor. The method comprises the following steps: 1) measuring the rotating speeds of a front wheel and a rear wheel which are at the same side through an optical-electricity encoder; 2) measuring a translational velocity of a vehicle through a low-speed radar sensor; 3) calculating to obtain the slippage rate of the whole tractor; 4) measuring various parameter values respectively according to different tilling depth during working in a farmland; 5) measuring traction force as the parameter value of the transportation condition during transportation; 6) processing the experimental data, wherein the measurement above is performed by groups, each group is subjected to at least three measurements to remove abnormal data, and effective test results are selected and sorted summed up. The test method of the slippage rate of the tractor has the beneficial effects that 1, two different working conditions of the tractor, namely, working in the farmland and transporting can be completely simulated, and thus the accuracy of the measured data is improved; 2, various measuring devices are used to further improve the accuracy of the measured data; 3, various traction force values are provided according to the application of a load trolley, so as to improve the measuring efficiency.

Description

technical field [0001] The invention relates to a method for testing the performance of a tractor, and in particular provides a method for testing the slip rate of the tractor. Background technique [0002] Slip is when the drive wheels actually travel less than they would have traveled in pure rolling. When the wheel or track is running on the ground, the ratio of the slippage per unit time relative to the ground in the opposite direction of travel to the theoretical speed. [0003] The traction adhesion performance of tractor has been paid attention to and researched by people all the time, because it directly affects the operation efficiency and fuel consumption rate of the tractor. The slipping of the driving wheels will affect the driving speed and driving force of the vehicle, consume the power of the engine, and increase the fuel consumption. Excessive slipping may also cause intense self-vibration of the wheels and reduce the operability of the vehicle. and passabi...

Problems solved by technology

The slipping of the driving wheels will affect the driving speed and driving force of the vehicle, consume the power of the engine, and increase the fuel consumption. Excessive slipping may also cause intense self-vibration of the wheels and reduce the operability of the vehicle. and passability

[0004] Agricultural vehicles work on the soil. If the slip rate of the driving wheel is too high, it will increase the rolling resistance of the tractor, and even cause the tractor to fail to operate normally, which will bring huge losses to agricultural production.
