In order to meet the needs of customers and take advantage customer's innovative resources, companies open up their design activities products customers. contrast traditional product innovation, primary characteristic innovation is participation a large number autonomous individuals across organisational boundaries, there not central authority. Hence, it necessary study dynamic mechanism for obtaining good decision. This paper first studies evolution individual interaction based on game...

In the process of collecting 3D point cloud data aviation blisk, it is inevitable to collect various noise points and background data, which will affect subsequent reconstruction process. Therefore, how extract effective blisk information retain accurate structural features as much possible an important step in preprocessing overall reconstruction. To this end, paper proposes a hybrid filtering algorithm denoise single-view remove noise. At same time, octree downsampling method used simplify...

As the consumer individualization is becoming stronger and customer demand changing more frequently, traditional manufacture-active design pattern cannot meet demands of present age. It widely acknowledged by experts that can be really realized if could participate in product process. At present, participation process through Internet quite prevalent, but methodology theoretical foundation have never been concerned previous studies. This paper proposes concept Open Design then investigates...

The traditional product design scheme can no longer fully meet the current user needs. To solve some problems that live in period of small and medium batch products' solutions, such as long cycles a lot differences between direction needs well high technical difficulty deep learning-assisted products. This paper proposes rapid update method for products based on knowledge graph, combining data mining Python module methods. aims to reasonably reduce requirements, obtain comments with...

Aiming at the problem that conventional target recognition algorithm is highly dependent on light and has a poor fruit effect in low dark environments, this paper proposes three-dimensional method based PointNet++. First, depth camera used to obtain point clouds construct dataset, then network trained using dataset. Finally, cloud recognized by network. The experimental results show PointNet++ can recognize both unoccluded partially occluded clouds, IoU of predicted real are 0.92 0.89,...

In view of the lack advanced and mature substation fault detection facility technology, combined with characteristics actual application environment substation, a operating equipment autonomous monitoring diagnosis system based on deep learning intelligent robot is proposed. That is, algorithm, Big data analysis technology patrol HD camera are organically combined. The image information collected by high-definition fused variety sensors, then tree algorithm used to carry out real-time all in...

Traditional ore size detection algorithms are mainly machine vision-based image segmentation algorithms, which cannot meet the requirements of industry in terms accuracy and real-time. Therefore, this paper proposed a deep learning network model based on YOLOv5 for real-time particle size. The location bounding box its width height information were output from model, then FERET was extracted. cumulative error rate between final distribution results actual less than 3%, performance good.

Aiming at the problem that traditional fault diagnosis method is difficult to effectively extract features of high-speed train wheelset bearing signal, this paper proposes a based on two-dimensional image method. First, one-dimensional vibration signal converted into Two-dimensional grayscale image, eliminating influence expert experience feature extraction process. Then an improved network model proposed, which can automate process and diagnosis. Finally, simulates complex driving...

As an advanced aerospace technology, the high speed aircraft has a broad technical prospect. Due to changeable flight environment, aerodynamic characteristics and thermal change dramatically. Therefore, process is prone instability out of control. In this paper, trajectory stabilization system studied address problem. Based on system, steady transient fluid simulations were performed. The stabilizer carefully at Mach 6 different altitudes in atmosphere. force stress structure calculated....
