Combine harvester seat stress test system based on PLC control

Abstract

A combine harvester seat stress test system based on PLC control can acquire vibration and pose signals generated at the bottom of a seat in the actual operation process of a combine harvester through a signal acquisition module, and accurately reproduce the movement conditions of vibration, pitching, side tipping and the like in the actual movement process of the combine harvester, carry out seat vibration reduction research by using the acquired data, then process vibration and pose signals acquired by the signal acquisition module through the signal processing module, and finally, control the motion platform to output high-precision simulation motion through a PID closed-loop control method, so that the data acquisition module can acquire more real data, a corresponding control method is provided, and the collected real motion data of the combine harvester in actual operation is used for seat vibration reduction research, so that the reliability, authenticity and the like of the research data of combine harvester seat vibration reduction research personnel are improved, and the method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of combine harvester testing, in particular to a combined harvester seat force test system based on PLC control. Background technique [0002] It is known that China is a traditional agricultural country, and combine harvesters, as a kind of mechanical equipment that can harvest agricultural products quickly and efficiently, have developed rapidly in China. The working environment of the combine harvester in the field is relatively harsh, and a series of uncertain vibrations will be generated during the working process. This series of uncertain vibrations will have a great adverse effect on the health of the driver. With the development of science and technology, the demand for optimizing the driving environment of agricultural vehicle drivers is constantly increasing. [0003] At present, all vehicle tests can be carried out on the test bench if conditions permit, which can save a lot of manpower, material...

AI Technical Summary

Problems solved by technology

However, due to the diversity of the operating conditions of the combine harvester, the existing loop function cannot truly reflect the vibration, pitch, roll, etc. of the actual movement of the combine harvester. The machine seat force test system has become a long-term technical demand for those skilled in the art
