摘要
为合理配置双钢轮振动压路机的动力系统,提高整机经济性,针对双钢轮振动压路机多系统功率耦合的循环作业特点,分析了作业过程中的负荷及功率需求,发现动态过程的功率需求远大于平稳过程。为减少多系统瞬态功率需求量,提出了削峰及双系统错峰的解决办法,并在样机上成功进行了试验验证。结果表明:对于双系统峰值负荷几乎同时出现导致的双系统所需功率之和较大的问题,采用错峰进行抑制。错峰时间为1s时,总功率需求降低了10%,降低总功率效果明显;对于动态起步起振中巨大的惯性负荷导致的双系统峰值功率偏大,采用控制系统动态过程的方式进行改善。斜坡输入0.3 s时单系统峰值降低可达32.7%。而上述两种措施联合使用则可使总功率降低达33%以上,大大的减小了整机动态功率需求,降低了装机功率,提高了整机经济性。
In order to optimize the operation mode and multiple power coupling system of the ma-chine, the load and the power demands were analyzed for configuring the power system rationally and improving the machine efficiency of the double-drum roller. It was found that the power demand in a dynamic process was greater than that of a smooth process. To reduce the demands of transient power, two strategies of reducing peak and stagger the double system peak were proposed and veri-fied on the prototype. The results show that staggering the peak has an obvious effect on suppressing the large power required by the sum peak load and the power demand was reduced by 10% in 1 s staggering time. The requirement of huge inertia load in the dynamic vibration can be improved by controlling the dynamic process of system. While slope input was 0.3 s, the single peak system was reduced by 32.7%. Dynamic power demand can be greatly reduced by more than 33% by combi-ning these two measures. The installed power and improve the economy of the roller can also be reduced.
