The windblown sand erosion wear and damage behaviors of the rail materials in windblown sand environment were investigated using a windblown sand erosion wear test machine, and the erosion wear and damage mechanisms of the rail in windblown sand environment were clarified. The rolling wear and damage behaviors of the rail in windblown sand environment were studied using a wheel-rail rolling wear and contact fatigue testing machine equipped with the device of the windblown sand environment simulation, and the rolling wear and damage mechanisms of the rail in windblown sand environment were...

Mechanized harvesting of oil tree peony fruit is an important condition for the industrialization of oil peony. It is of great significance to improve the self-sufficiency of edible oil and solve the contradiction between supply and demand of edible oil. However, the existing oil tree peony fruit harverster can only partly meet the needs of mechanized operation, but the cutting mechanism of the stem and cutting tool parameters is still lack of sufficient theoretical research, and the optimal design of the fruit harvester has not been realized. Therefore, this paper considered the oil tree...
