The Dynamic Simulation And Analysis Of Hydraulic Break Hammer's The Working Device Based On ADAMS

Hydraulic Break hammer is one of mechanical equipment which transforms hydraulic energy into machine energy. It works as hydraulic force to push the piston. Analyzing the principle of dynamic change of pressure and flow by computer simulation is very important to improve the work efficiency and reliability while reducing the energy consumption.In terms of the kinematic scheme analysis of work equipment of the hydraulic break hammer, its kinetic model is established, and its basic design parameters and whole ones are determined in this research work. Subsequently, the 3D modeling and virtual assembly of the work equipment are accomplished in the Pro/E software, and by the 3D visualization interferential checking and the kinetic locus and wrapping analysis, the validity of the established kinetic model is verified. At the same time, the finite element analysis is performed for the work equipment.In addition, by means of the classical dynamic simulation software ADAMS, the multi-rigid bodies virtual prototype machine is built for the work equipment of the mining anti-explosion loader. Via the kinematic and dynamic simulation based on the multi-rigid bodies dynamics theory, the kinetic and dynamic characteristic curves of the work equipment are obtained. Based on these investigations, the virtual prototype machine coupling rigid bodies with flexible ones is established eventually. By comparing the obtained the kinetic and dynamic characteristic curves and the corresponding simulation results from the latter with those of the former, it is shown that the virtual prototype machine with flexible bodies is more accordant with the physical prototype machine than the former.Pro/E and ADAMS are used to solve the actual engineering problem in this paper which introduces the strong function of advanced computer analyzing software in practice. The author perceives the prospective of the above is very broad, and will bring great profit, with the development of computer technique, it is a must.The research work provides with a valid method to design and study the working device of hydraulic break hammer. The obtained conclusions have important instruction significance to trial-produce and performance evaluation of the physical prototype of work device. It also has reference value for the kinetic and dynamic simulation and the establishment of the virtual prototype of other complicated mechanical devices.
