Research on Design of Parameters of Vibration-impact Rammer Based on Virtual Prototyping Technology

The defect of conventional method for the construction of model and analysis of vibration-impact rammer was analyzed firstly. A parameterized virtual prototyping model of vibration-impact rammer was build up by using Pro/E and Adams. Some key problems were solved in the process. Virtual prototyping technology was used to carry out the modal analysis and dynamic response analysis for vibration-impact rammer. The detailed analysis of the effects of the design parameters of vibration-impact rammer on the work characteristics of the machine was completed through the simulation test. Optimization design for vibration-impact rammer was implemented. Based on the result of the simulation, structural optimization of the connection rod was carded out, too. The design principles and optimal method for vibration-impact rammer were proposed on the base of the analysis.
