摘要
为了在保证双钢轮振动压路机压实质量的前提下合理匹配整机功率,根据压路机循环作业的负荷特性,提出了双钢轮振动压路机的并联混合动力系统方案及控制策略。以某双钢轮振动压路机混合动力行走系统为例,采用AMESim和ADAMS联合仿真方法分析了从高速起步到停车制动的一个载荷循环过程。仿真结果表明:起步和制动过程发动机转速波动范围比原系统减小一半以上;稳定压实过程行走速度稳定;发动机的输出转矩被限制在150N.m以内,制动能量得到有效回收;循环过程实现了电池荷电的维持。与原系统相比,本文并联混合动力系统在保证压实质量的前提下,整机功率匹配更合理,功率利用率更高。
To reasonably match machine power under excellent compaction quality, parallel hybrid power system for tandem vibratory rollers and its control strategies were put forward based on the analysis of cycle load characteristics of the rollers. Taking the hybrid driving system of a tandem roller as an example, the load cycle from high speed starting to braking and stopping was investigated using AMESim and ADAM simulation. Simulation results show that the engine speed fluctuation is cut down more than 50% in starting and stopping process, the driving speed is stable in compaction process. The engine output torque is limited to 150 Nm and the braking energy is effectively recovered, which keeps the balance of the charge of power cells in a working cycle. It is demonstrated that the parallel hybrid power system of tandem vibratory rollers and its control strategies are correct, the power is matched more reasonably with higher utility rate and compaction quality compared to original hydraulic system.
