Bridge Culvert Back Side Of The Compaction Equipment

The general situation and development of road roller at home and abroad is gave at the beginning of this thesis, including the different pressing mechanism of various rollers. It is analyzed that the useable range of various roller and their advantages and disadvantages. On the basis of model mechanism design and experiment of those self-moving vibrating pressing machine, it is reached the principle and program of a new type of pressing mechanism-vibrating and impacting pressing machine. According to the theory of vibrating and impacting pressing, the main parameters of this vibrating and impacting pressing model machine is decided. Mathematical model is set up by kinetic analysis. At last, the comparative experiment is taken on in the condition of low-frequency , middle-frequency and high-frequency comparatively, tests including the pressing-degree of this machine, running-velocity, vibrate character and productivity. The result of experiment is the basement for parameters optimization and improvement of the machine.
