Simulation Of Hydraulic Impact Crushing Hammer System And Optimization Design Of Drill Rod

Currently our entire social modernization and industrialization process has not beencompleted, hydraulic impact hammer which gives such a large construction machinery tocreate a very strong market demand. Hydraulic impact hammer through more in-depthexploration understood hammer fatigue life, other internal structure, working principleand Rod problem for the design of operational safety, manufacturing process is simpleand can save energy with high efficiency hydraulic hammers provide a theoretical basisfor improving domestic hydraulic breaker overall technical strength and improve thewell-known brands in the global core competency is necessary. For this reason, theoverall structure of hydraulic breaker design and key components such as hammer drillrod simulation studies, efforts to narrow the distance and international core technologies,enhance domestic Hammer technology content, in order to create a more brand benefitsociety has a very positive meaning.This paper illustrates the differences in hydraulic hammer theory research at homeand abroad, the application range of the hydraulic hammer, the advantages anddisadvantages of hydraulic hammer, the need to improve the deficiencies and the maintrend of future development. This paper selects certain domestic models of hydraulichammer as the research object, research focused on the following three aspects:First, its basic structure and working principle of impact crusher study discusses thehammer selection and the role of key components and failure modes.Second, the use of Solidworks software for hydraulic hammer drill rod stressanalysis, fatigue analysis, fatigue life calculation brazing rod.Third, the basic principles of fatigue damage accumulation elaborate and fatiguecumulative damage theory based on the fatigue life of the drill rod to estimate. These tworesults were compared for the purpose of verification Solidworks software for fatigue lifeestimation accuracy. This paper studies the methods focus on the combination of theoryand practice to improve the performance of hydraulic breaker for further research and laya good foundation.Figure30; Table3; Reference45...
