The Design And Research For Key Structure Of New Scissors Aerial Work Platform

The Scissors Aerial Work Platform is an equipment used to transport personnel, tools and materials to the designated location, with safe and reliable, simple operation, good trafficability and good stability, etc. Recent years, along with the rapid develop-ment of our national economy and urbanization, flexible Aerial Work Platform starts widely used in shipbuilding, building decoration, municipal garden, electric power communication, airport station and port construction or other places, the market demand is soaring.This paper based on the6m platform height Scissors Aerial Work Platform as the research object, systematic analyses the Aerial Work Platform development and research status, selects Aerial Work Platform overall scheme and each module scheme combining with the Aerial Work Platform structure and technical characteristics. Establish the structure model and stretching structure mechanics model of New Scissors Aerial Work Platform. Establish the structure model of shear fork arm, chassis wheel carrier and chassis frame, make finite element analysis. Research the function requirements of driving system, lifting hydraulic system and control system, constructs the logic relationship and design principle diagram of three systems. Analyzes the related theory about the fatigue life, combined with the static calculation and finite element static analysis, apply the nominal stress method research the fatigue life of shear fork arm, predict the fatigue life of the shear fork arm, to get fatigue damage distribution of the shear fork arm.Through statics analysis, finite element analysis and fatigue life analysis of the shear fork arm, master concentration of stress and the location of maximum fatigue damage of the shear fork arm, estimate fatigue life of the shear fork arm, finite life design on it, and optimize structure to provide a reference for the shear fork arm design. The research work of this paper provide a certain theoretical basis and design basis for the subsequent design of Scissors Aerial Work Platform, and the research method has a certain actual reference value.
