摘　　要：为了双频合成振动压实技术的工业化应用,在前期小型试验样机研究的基础上,研制了20t级双频合成振动压路机的工业样机。采用现场对比试验方法,完成了工业样机的性能试验和与常规同吨位压路机的对比试验。试验结果表明:双频合成振动压路机工业样机任一挡位实现了2个频率及其振幅的合成;可靠性符合国家标准要求;与常规同吨位振动压路机相比,压实效果较好,中下层压实度分别提高2.1%和3.4%,具有明显的深层压实优势;起振过程液压系统压力冲击相当,平稳工作时振动功率相近;停振过程液压冲击较小,停振时间变短,停振更柔和。说明双频合成振动压路机工业样机满足设计要求,工作性能优于同吨位常规机型,可工业化推广。In order to obtain industrial application of double-frequency composed vibratory com- paction, 20 tons industrial prototype with double-frequency composed vibratory roller was de- signed 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 com- pared. 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.
