Dynamic impact response analysis and simulation on grader blade

The crack on grader blade was often occurred in the process of impact, in order to avoid this failure, analyzing the shock resistance of blade was extremely essential. Base on this background, a method to analyze and simulate the shock resistance of blade is preliminarily proposed, a characteristic curve on shock resistance of blade is also obtained based on kinds of impact accelerations. Firstly, the finite element analysis model was established, impacts of kinds of obstacles were transferred into impact force loads, the impact characteristics of blade were acquired rapidly based on dynamic explicit finite element method. Subsequently, the impact force loads were transformed to impact acceleration loads, the finite element models under kinds of impact accelerations were analyzed and simulated, the characteristic curve on shock resistance of blade was drawn at last. It indicates that the blade can bear the impact acceleration with almost 10m/s², which could provide reference for optimization design and engineering test, also could guide customers to use grader properly.
