摘要：Build cutting resistance measurement system based on single-chip microcomputer and high speed camera in order to analysis cutting destruction of solid ice-snow. The experimental model has been built according to the rotating orthogonal experiment methods when tests, take the cutting resistance as objective function, A significant factor in the depth of cutting, rake angle as well as tool installation angle as influencing factors, and analysis found that the relationship between the primary and secondary factors were setting angle>density>cutting depth. By comparing theoretical models and experimental models found both the maximum error is about 8.7%, the minimum error is about 12.8%, the median error of about 12%, which verified the availability of theoretical model. Affecting the snow removal efficiency of parameters were carried out the optimal tests study, and found that the best setting angle of cutting tool is from 46°to 52°on the condition that the temperature is lower than -15°C, the thickness of snow and ice is less than 35mm, and rake angle -10°~ -9°.Optimal combination of parameters meet not only the job requirements but also provide a valuable reference for the optimum design of snow removal tool structure and process parameters, and the overall design of a prototype in the future.
