With the increasing attention of energy saving and emission reduction technology, recent application hybrid powertrain technology affects development construction machinery industry. This article reviews these publications provides comprehensive references. state-of-art for wheel loader excavator, which focuses on configuration, storage devices, management strategies. The basis classification characteristic each configuration are described. Advantages disadvantages batteries,...
Optimized torque‐distribution control method (OTCM) is a critical technology for front/rear axle electric wheel loader (FREWL) to improve the operation performance and energy efficiency. In paper, longitudinal dynamics model of FREWL created. Based on model, objective functions are that weighted sum variance mean tire workload minimal total motor efficiency maximal. Four nonlinear constraint optimization algorithms, quasi‐newton Lagrangian multiplier method, sequential quadratic programming,...
Estimation of the center gravity (CG) is basis for intelligent control front-and-rear-axis-independent electric driving wheel loaders (FREWLs). This paper presents a novel real-time method estimating CG FREWLs, which suitable and spading conditions on bumpy roads. A FREWL dynamical model proposed to set up state-space model. The estimator used estimate longitudinal tire force using improved square-root unscented Kalman filter (ISR-UKF) algorithm. simulation experimental results indicate that...
This paper presents a rational prediction of temperature field on the differential hybrid system (DHS) based thermal network method (TNM). The whole model is built by considering both contact resistance between gasket and planet gear effect physical property parameters lubricant. obtained using concept branch G-W elastic model. By building an elaborate computing models for power losses resistances components, DHS under typical operating condition predicted. Results show that can be...
Monitoring of fracture orientation is significance in the exploration and development coal-bed methane; for this purpose, a monitoring system, based on principle differential electric resistivity tomography, has been widely used. The resolution scope determine detection depth methane fracturing layer. In article, system with less than approximately 10 µV 90 channels reported using virtual instrument technology. Based three-dimensional geoelectric field vertical finite line source by...
The development of sponge cities advocates for sustainable urban rainwater management, effectively alleviating flood disasters, reducing non-point-source pollution, and promoting the recycling resources. Low-Impact Development (LID) serves as a key strategy in this context, providing essential support control pollution reduction. To investigate runoff effects LID measures to reveal relationship between facility performance installation scale, study focuses on community Beijing. A SWMM model...
