Abstract:
In order to obtain industrial application of double-frequency composed vibratory compaction, 20 tons industrial prototype with double-frequency composed vibratory roller was designed based on experimental results of small prototype. The performance of industrial prototype and 20 tons ordinary vibratory roller was tested by field experiments and the results were compared. The results indicate that the industrial prototype at any time could realize composition of two frequencies and their amplitudes, and its reliability can meet national standard; the industrial prototype has obvious superiority in deep-seated compaction, which has better compaction ability than ordinary vibratory roller; compaction degree of midsoil and subsoil is improved by 2.1% and 3.4% respectively; the shock of the hydraulic system of the roller is the same in the process of starting vibration; the vibration power is similar in steady work; in the process of stop shock, the shock of hydraulic system is less and stop vibration time is shorter, and stop shock was softer. It was proved that the industrial prototype with double-frequency composed vibration meets design requirements and has higher performance than ordinary vibratory roller,and can be developed in industrial application. 5 tabs, 8 figs, 10 refs.
