Problems solved by technology

[0003] However, the existing experimental equipment is insufficiently automated, and operators are usually required to manually collect and analyze data. Data collection takes a lot of time and easily leads to deviations in experimental data. At the same time, manual measurement has large errors, which affects the accuracy of data. In addition, it increases the workload of the operator and requires the cooperation of many people to complete the experiment, so the operation is not convenient enough

Embodiment 1

[0032] Manual control can use the "lift up" button on the electric control cabinet 18, and the tractor lifter lifts the loading cylinder 24 to drive the suspension rod 5 to rise slowly. When the suspension rod 5 reaches the set position, the accumulator is quickly unloaded. And press the "displacement point confirmation" button, the suspension rod 5 stops at the designated position, record the lifting force, suspension displacement, column angle, loading cylinder angle, pressure and temperature of the tractor oil tank and oil cylinder pressure, temperature, suspension The lifting force is transmitted to the industrial computer 17 for display and stored in the excel file through the OPC software.

Embodiment 2

[0034]The automatic control is completely controlled by the S7-1200PLC module in the electrical box 15. The user can manually set the sampling points on the interface, up to 10; after setting the upper limit and the lower limit of the displacement, let the industrial computer 17 Automatically set the sampling points equally. After setting, press the "Start" button, the driver can operate the tractor to start the experiment. The suspension will automatically stop at the designated position, and the dwell time is 10S by default, which can also be modified; if you want to enter the next test point immediately, you can press the "displacement confirmation" button, and the suspension will immediately rise to the next set point. When reaching the highest point, you need to switch to the manual control mode, lower the suspension to the lowest point, and then do the second set of experiments, a total of three sets of experiments can be done.

Abstract

The invention discloses a tension test platform for a tractor suspension device, comprising a tractor body, an experimental platform, a sensor group and a console, wherein a suspension rod is fixedlyconnected to the suspension position of the tractor body, an experimental groove and a limiting rod are provided on the surface of the experimental platform, the limiting rod is fixedly connected to an edge of the experimental groove, a hydraulic assembly and a cylinder assembly are fixedly connected into the interior of the experimental groove, and an output end of the cylinder assembly is connected to the suspension rod; the sensor group comprises a tension sensor, an angle sensor, a temperature sensor, an oil pressure sensor, and a displacement sensor mounted on the surface of the suspension rod; and the console comprises an electrical box, a signal processing box and an industrial computer. A manual control mode and an automatic control mode are used and cooperate with automatic data acquisition and analysis to improve the convenience of experimental operation for an operator, and the sensor group is used to monitor experimental parameters so as to improve the accuracy of experimental measurement and the timeliness of data recording.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment testing equipment, in particular to a tractor suspension device tension testing platform. Background technique [0002] At present, most of the lifting capacity test benches for tractor suspensions at home and abroad adopt the structural form of manual loading or cylinder hydraulic loading. [0003] However, the existing experimental equipment is insufficiently automated, and operators are usually required to manually collect and analyze data. Data collection takes a lot of time and easily leads to deviations in experimental data. At the same time, manual measurement has large errors, which affects the accuracy of data. Sex, and increase the working intensity of the operator, and need many people to cooperate to complete the experiment, the operation is not convenient enough. For this reason, need to design a kind of new technical scheme to give solution. Contents of the inventio...
