The header is the most important part of the corn harvest, and the structure of the stripping roller determines the results of stripping and stalk pulling. In order to improve the efficiency and integrity of harvesting, a new type of harvesting roller was designed. Based on the working principle of the snapping roll, the spiral round steel and the snapping claw are welded on the body of the snapping roll in the way of straw feeding and entering the snapping roll under the action of the grain divider. In order to verify the rationality, the snapping roll was simulated to verify the rationality of the structure design.

The Baja Competition of China Society of Automotive Engineering has been held for six times since it was held in 2015. It is mainly for the design and production of small off-road vehicles carried out by vocational and undergraduate colleges. The competition requires each participating team to design and manufacture a single-seat, mid-engine, rear-drive small off-road vehicle using the same type of engine within the specified time, and participate in a number of static and dynamic project tests. This paper mainly introduces the design and manufacture process of two-drive Baja racing car, so that readers can better design and manufacture the parts of racing car, but also stimulate readers to choose more reasonable materials, trying to achieve a lighter, more stable, faster racing car. In this paper, the author put forward the car brake disc can be improved in what aspects, for readers to further explore independently. I hope this paper can help the students who participate in Baja auto competition and all the friends who are interested in car construction and car design.

In this paper, an adaptive controller design method is proposed for chaotic systems with unknown actuator dead-zone. First, the terminal sliding mode (TSM) manifold is proposed to ensure exponential stability as well as faster finite-time stability. In addition, a neural network (NN) is introduced to estimate the partially unknown nonlinear dynamic behavior of the object, and according to the implicit function theorem, the unknown asymmetric dead zone of the actuator is overcome by another static neural network. Furthermore, a robust terminology updated online deals with refactoring errors and external interferences of neural networks. Finally, the system can stably track any smooth target trajectory online is rigidly proved via Lyapunov analysis, and numerical simulation shows its effectiveness and feasibility.

Fish detection is an important technology to achieve intelligent, accurate and appropriate feeding of fish. The detection rate of traditional detection methods is low and the state of the fish school will have a certain impact on the accuracy of the feeding strategy. In order to improve the recognition rate and obtain the state of fish school, a low-resolution image fish detection method based on Halcon software and MobileNetV2 network is designed. The position coordinates and head orientation of fish are extracted to analyze the movement characteristics of fish school by MobileNetV2 network. The experimental results show that the detection method has a high recognition rate for fish detection. This method provides an important reference value for the design of automatic fish feeding system.

The electro-hydraulic servo valve is the core component of the hydraulic system, so the electro-hydraulic servo valve is the key object in the maintenance process of the hydraulic system. Therefore, it is very important to study the fault of electro-hydraulic servo valve. Set up an experimental platform to measure the data under 3MP, 3.5MP, 4MP, 4.5MP and 5MP. After analysis and tradeoff, it was finally decided to use Adam, Momentum and RAdam optimization algorithms to realize the fault diagnosis of electro hydraulic servo valve. The data are organized into 37 dimensional arrays as samples for training. The first 32 dimensions are the characteristic parameters of the electro-hydraulic servo valve, and the last 5 dimensions correspond to five fault modes. The test set is 32 dimensions, and the diagnosis result is 5 dimensions corresponding to a fault mode. The diagnosis result is in line with expectations.

Spherical tanks are the key storage equipment in the chemical production process. Grinding the outer wall rust layer and performing non-destructive testing are important means to ensure safe operation. Traditional rust removal methods mainly rely on manual labor, which are inefficient as well as seriously harmful to human health and environment. In this paper, a high-pressure waterjet robot system for external rust grinding was designed to replace manual operation of petrochemical spherical tanks. Magnetic wheels were used to realize adsorption and the robot can crawls steadily on the vertical wall of the spherical tank. Meanwhile, a robot anti-fall system was designed to ensure the safety, and a vacuum recovery system was designed to recover rust residue during operation. The application of the robot can sharply reduce the labor intensity and danger of rust removal work, as well as improve the working environment. Test results showed that the grinding effect of the robot met the requirements of subsequent non-destructive testing.

Traditional EMU bogie business data production and processing are concentrated at the edge. Today, under the background of big data, cloud computing, and artificial intelligence technologies, it is not only required to process a large amount of data but also the core task is to quickly complete data mining processing and to explore tacit knowledge. The end-cloud synergy architecture combines the end and the cloud to achieve complementary advantages. With an acceptable delay, the computing power shortage of the end can be solved, and the cloud's elastic distributed processing capabilities and rich data model-building capabilities can be used to improve the overall computing power and application ability. Aiming at the business data processing of EMU bogies, this paper proposes a data tag collaborative processing method architecture based on end-edge-cloud. The data is mainly marked at the edge layer. After sending to the cloud, the cloud can quickly scan, clean, classify, store, and process based on the data marking rules. Meanwhile, the labeled data can be used for model training to strengthen the model. This paper also builds a simulation system to conduct experiments to verify the effectiveness and advancement of the method.
