A concave disc copying icebreaking snow sweeper has been developed for improving the work efficiency and clearing free rate of solid ice and snow, and meeting the rapidity and efficiency of solid snow removal. The machine can simultaneously complete five functions of crush, chop, lifting, scraping and pushing, which also can realize independent servo-copying and self-excited vibrations reduction drag avoidance functions. The structure and working principle of the concave disc copying icebreaking snow sweeper have been introduced. The optimal combination of operating parameters impact on the clearing free rate and efficiency has been determined. The combinatorial optimization test methods of quadratic regression orthogonal rotation center was adopted, the traveling speed, digging depth of the snow, the blade angle of concave, the travel angle of concave blade are made as impacting factors, snow resistance, the clearing free rate, the maximum volume of removing snow pack as the objective function, optimizing experimental studied on the impact of performance of the snow machine operating parameters. The results showed that: the effect of copying and crossing obstacle in machine is good, effectively solve the problem of low clearing free rate of solid ice, while the efficiency of snow removal has been improved. According to the principle of objective function: the smaller snow resistance, the higher clearing free rate, the maximum volume of snow pack, making each factor level interval as constraint optimization, when the snow resistance is smaller than 820N, the clearing free rate is greater than 96%, the maximum volume of snow pack is smaller than 612mm3, the traveling speed ranges from 6km/h to 9.7km/h, the blade angle of concave blade is 19~ 21°, the travel angle of concave blade is 12°~14°. The above operating parameters are the optimal combination of snow machines.
