Efficient Roller Performance Study

Modern highway construction is more and more high to the requirement of its quality and design standards, in addition, the importance of highway construction on the basis of economic development of our country is becoming more and more importint.Therefore, the performance requirements in construction machinery are in urgent need to improve.And the performance of roller is directly affects the construction of pavement compaction, flatness, etc., so how to improve the performance of roller research topic to improve the quality of the highway construction of our country is of great significance.Impact vibration compound compaction equipment is to explore the new theory and compaction compaction technology under the condition of development, it will be a single type of impact roller and the vibratory roller by combining both performance, make its can form at the same time in one machine with static ground shock, vibration and three types of compaction equipment.This will undoubtedly make compaction work efficiency greatly improved, and can achieve better compaction effect.This treatise firstly introduces the current market of compaction equipment performance characteristics, and then theoretically proved the feasibility of impact vibratory roller products, according to the similarity theory in the similar structure and size of the same and have similar performance, engineering prototype design.A dynamic model of roller- soil system, combining the mechanical principle of soil mechanics and research, improve the impact vibratory roller compaction technology and theory.Through the three dimensional modeling software Solidworks to build major components geometry entity model;Considering the diversity of the soil properties, improve the authenticity of the simulation results, parameterization of flexible body is generated by ANSYS to simulate the ground;Using the ADAMS software to a series of dynamic simulation entity model, to analyze the simulation results, it is concluded that the influence of working parameters on the compaction effect.According to the simulation results and theoretical analysis, it is concluded that the degree of compaction and the main kinds of compaction and the changes of process parameters and the regularity of the relationship between the parameters, this paper studies some of the results, the deeper impact vibration compaction technology research is very useful, for some complex conditions of subgrade compaction and cohesive soil compaction problems provides a feasible solution, the practical application of engineering also has some beneficial to value.
