摘要

为了提高液压挖掘机的能量利用率，在分析挖掘机流量再生结构原理的基础上，提出了一种基于实测载荷谱的流量再生特性试验装置。试验装置采用电动调节溢流阀加载方式，可以模拟真实工况的负载谱。建立了AMESim仿真模型，采集实车臂架油缸入口和出口在臂架下降状态下的载荷谱，并将其输入到AMESim仿真模型中。通过试验与仿真的对比分析，验证了流动再生试验装置与仿真模型的正确性，为流动特性再生的技术研究提供了新的思路。

Research on Excavator Flow Regeneration Characteristics Based on Measured Load Spectrum and Simulation Load Spectrum

In order to improve the energy utilization rate of hydraulic excavator, based on the analysis of the principle of flow regeneration structure of excavator, a flow regeneration characteristic test device based on the measured load spectrum is proposed. The test device adopts the loading mode of electric regulation relief valve, which can simulation the load spectrum of real working condition. The AMESim simulation model is established, the load spectrum is collected from the real vehicle of the boom cylinder inlet and outlet under the condition of boom lowering and is input into the AMESim simulation model. The correctness of the flow regeneration test device and simulation model is verified through the comparision and analysis of the test and silulation, which provides a new idea for the technical research of the flow regeneration on characteristics.
