Dynamic Analysis Of The High-speed Hydraulic Rammer System

The high-speed hydraulic impact rammer which has compact structure than staticrammer has been widely used because it can create impact energies by using impactexercise of tamper. The article is researched on dynamics of the high-speed hydraulicimpact rammer. The purpose of the article is to explore dynamics process ofhigh-speed hydraulic impact rammer. The key dynamics parameters on optimizinghave been given which will provide operation efficiency, operation effect andmechanical reliability.The mechanical system dynamics of the high-speed hydraulic impact rammer isresearched in this paper. Also the development situation of hydraulic impact rammerat home and abroad is analyzed, and then the structural composition, workingprinciple, hydraulic system and electronic control system of the high-speed hydraulicrammer are investigated. On the basis of the theory of wave mechanics and vibrationmechanics, dynamic analysis is made for its working process and displacement andspeed function is obtained. Then software Solidworks is used to establishthree-dimensional solid model of high-speed hydraulic impact rammer and softwareADAMS/View is used to build the dynamic model and simulation analysis is made byADAMS/View. It also obtains the relationship between impact compaction force andrammer, tamper and some key parts such as frame of the high-speed hydraulic impactrammer and the stiffness of tamp medium then do some related experimentalverification.Theoretical research and simulation analysis and experimental verification on thedynamics of high-speed hydraulic impact rammer is explored, dynamics and energyconversion relations in the work process are obtained. The study provides for theoryon the structural design of mechanical system and performance evaluation for a newhigh-speed of hydraulic impact rammer theory.
