The Design And Research Of Electric Four-wheel Mower

Electric mower in China is still in its infancy. There are no perfect design referencestandards of quality control for new product, and the paper analyzed the structural designrelated to safety specification and the factors in the implementation process of the mainperformance of electric mower, proposing the feasible countermeasures.(1)Reviewed the development and research of the electric mower, and described theneed for design analysis of electric four-wheel mower;(2) By reference to domestic and international standards, analyzed the requirements ofsafety specifications in detail for the electric four-wheel mower and specific methods andprecautions to achieve and meet the requirements;(3) Elaborated the electric four-wheel mower cutting efficiency, grass-collectingefficiency, braking, noise performance etc. functional indicators, and analyzed theassessment methods and influencing factors of every indicators, indicating the designessentials of blade angle, the height of the duct, the blades move unbalance, belts brake andcentrifugal clutch brake. Considered the user experience and influencing factors of everyperformance and functional indicators from the use of perspective, and elaborated theprinciple, methods, the range of applications and the precautions in the design for the twobrake control mechanism of the mower.(4) Made use of software FLUENT to do the stress-strain analysis for transmissionbearings which is the core components of electric four-wheel mower, and by contrast withthe actual failure, summarized the design essentials of transmission bearings in the designand process.(5) A summary of the work was done.The paper has analyzed and studied the design of the electric four-wheel mower indetail, using the FLUENT software to do the static stress-strain analysis for transmissionbearings which is the core components of electric four-wheel mower and summing up theessentials of the bearings in the design and process. The study has great reference value forelectric four-wheel mower R&D personnel during design and development.
