To solve the demand for road damage object detection under resource-constrained conditions of mobile terminal devices, in this paper, we propose YOLO-LWNet, an efficient lightweight algorithm devices. First, a novel module, LWC, is designed and attention mechanism activation function are optimized. Then, backbone network feature fusion further proposed with LWC as basic building units. Finally, YOLOv5 replaced. In two versions small tiny, introduced. The YOLO-LWNet was compared YOLOv6 on...
To address the issue of performance testing hydraulic rock drills under specific working conditions, a stiffness–damping multi-stage adjustable simulation system has been proposed. Firstly, based on Kelvin theory, vibration model nonharmonic excitation is established. An integer-order created fluid mechanics theory. The characteristics granite and are studied, discussing influencing factors characteristics. Next, drop hammer calibration experiment an impact drilling for designed. Finally, in...
Summary To enhance the efficiency and prolong battery life of hybrid energy systems equipped with supercapacitor for a pure electric loader, this paper proposes real‐time management strategy based on model predictive control (MPC). First, working characteristics loader topology structure are analyzed. Second, considering repetitive operation loaders, neural network algorithm long short‐term memory is used to predict power dynamic programming as rolling optimization solution MPC strategy....
With the wide application of electric vehicles and development battery technology, pure construction machinery (PECM) has received more attention due to its high efficiency no pollution. The working conditions are complex accompanied by periodical heavy load. For machinery, a load represents an energy supply with large current. To adapt PECM, this paper proposes robust controller regulate current hybrid system (HES) which include supercapacitor. V-type operating 5-ton loader research focus...
In response to the issues of overheating shell and insufficient impact energy hydraulic rock drill, this paper focuses on drill with alternating front rear return chambers. By establishing nonlinear linear dynamic models, influence stroke amount flow compensation system is investigated, an optimization method for characteristics proposed. Considering factors such as clamping force, fluid leakage, properties, a feedback control numerical model established system. This based principles drawn...
<title>Abstract</title> The rock simulation system is of great significance for the development high-frequency high-power hydraulic drills. It can simulate different drilling conditions in specific environments and observe effects under multi-scale conditions. This paper proposes a multi-stage adjustable with variable stiffness damping. Firstly, based on Kelvin theory, vibration model non-harmonic excitation established. Combining characteristics adaptive oil-gas suspension rigidity locking,...
