Road power generation technology is of significance for constructing smart roads. With a high electromechanical conversion rate and bearing capacity, the stack piezoelectric transducer one most used structures in road energy harvesting to convert mechanical into electrical energy. To further improve efficiency this type harvester (PEH), study theoretically experimentally investigated influences connection mode, number layers, ratio height cross-sectional area units on performance. Two types...
Aiming to alleviate traffic congestion, many congestion avoidance and optimization systems have been proposed recently. However, most of them suffer from three main problems. Firstly scalability: they rely on a centralized server, which has perform intensive communication computational tasks. Secondly unpredictability: use smartphones other sensors detect the congested roads warn upcoming vehicles accordingly. In words, are used solve problem rather than avoiding it. Lastly, infrastructure...
With the increase of organic matter content in global water bodies, timely and accurate identification algae objects bodies is great significance for rapid treatment eutrophication.To improve performance seaweed microscopic image recognition model, an improved concave matching algorithm was designed applied to segmentation original images.In addition, IResNet with self-adjusting pooling layer designed.In this study, ResNet were used construct a model.The average Accuracy Precision proposed...
Multi object tracking (MOT) is a key research technology in the environment sensing system of automatic driving, which very important to driving safety. Online multi needs accurately extend trajectory multiple objects without using future frame information, so it will face greater challenges. Most existing online MOT methods are anchor-based detectors, have many misdetections and missed detection problems, poor effect on extension adjacent when they occluded overlapped. In this paper, we...
Structural materials damages are always in the form of micro-defects or cracks. Traditional conventional methods such as micro and macro examination, tensile, bend, impact hardness tests can be used to detect damage defects. However, these destructive nature not real-time, thus a non-destructive real-time monitoring characterization material is needed. This study focused on application acoustic emission (AE) method performance degradation high-strength aluminum alloy high-speed train gearbox...
The key material of high-speed train gearbox shells is high-strength aluminum alloy. Material damage inevitable in the process servicing. It great importance to study for in-service gearboxes train. Structural health monitoring methods have been widely used recent years. This focuses on application an acoustic emission (AE) method quantify tensile evolution First, a characteristic parameter was developed connect AE signals with damage. Second, quantification model presented based...
In operating conditions, real time non-destructive testing (NDT) is needed for the identification of tensile damage process high-speed train gearbox shell. This paper focuses on application an acoustic emission (AE) method to study damage. First, tests with AE monitoring were employed collect signals and data. Second, feature extraction was performed obtain vectors characterize Then, Support Vector Machines (SVM) Weighted (WSVM) used identify different stages material
The high-speed train gearbox is one of the key components system, and its working state related to passengers’ safety. shell protective for gears under harsh complex service environment. Instantaneous impact hard material during failure can lead rapid damage accumulation fracture material. In this article, tensile has been studied. For short process leading significant amount damage, a real-time non-destructive detection method used monitor progression predict residual life An automatic...
