A method for optimize that performance and evaluating the effect of lubricate drag reduction components

Abstract

A method for optimize that performance and evaluating the effect of lubricate drag reduction operation part features that the lubricating drag reduction operation part provides multiple aperture, theaspect ratio of surface groove, the pressure in hydraulic system of lubricating drag reduction indoor testing device and the change of forward speed. The optimization variables and indexes of the relationship model between multi-objective and traction resistance are constructed, An evaluation method is provided to optimize subsoiling resistance through different weighting coefficients without sacrificing tillage effect by changing subsoiling operation component parameters, optimizing subsoiling shovel operation effect, reducing target level stress, guiding scientific research and production, eliminating field test in research and development, saving time and labor, and improving research and development efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a performance optimization and effect evaluation method of lubricating and drag-reducing operation parts, which can reasonably evaluate the drag-reducing operation effect of indoor soil tanks. technical background [0002] Subsoiling technology is an important conservation tillage technology. Subsoiling operation effectively breaks the bottom layer of the plow, promotes the exchange of soil gas, liquid and solid three-phase media, enhances the water storage capacity of the field, and effectively kills weeds, diseases and insect pests. It is of great significance to increase production and improve quality. [0003] The adhesion of the soil to the soil-touching parts and the cutting force of the soil-touching parts have a great influence on the operation effect, efficiency and quality of the subsoiling operation. These problems have greatly hindered the popularization ...

Problems solved by technology

Since the research on drag reduction of lubricated subsoiling is still in the initial stage, the relationship between flow, pressure, forward speed and traction resistance in the hydraulic system is still unclear. There are limitations in all aspects. In order to clarify the operation mechanism of lubrication and drag reduction subsoiling, and better design the relationship between hydraulic parameters and working parameters, it is urgent to design and propose a test sample and its operation based on the lubrication subsoiling indoor test bench. Evaluation method of effect

[0004] After searching the literature of the existing technology, it was found that the Chinese invention patent "Mechanical subsoiling operation quality detection and evaluation method and system" patent application number 201610078173.4 uses the ARM platform to detect the operation area and depth to evaluate the quality of subsoiling operations. The invention patent is suitable for daily subsoiling operations, but not for the research and devel
