Modern Manufacturing

It is a common phenomenon that 3D model and 2D engineering drawings are widely used together in modern manufacturing scenario. Therefore it makes a lot of extra tasks to do for both of them which lead to such results as high time consuming, labor intensive during the process. The Model-based Definition (MBD) approach is definitely an effective method to solve above problems. To facility the usage of the MBD Technology, this paper introduces two kinds of MBD model (design-MBD, process-MBD), and describes their contents as well. The paper also focuses on constructing the dMBD model and pMBD model from two aspects: information organization and annotation standard so that these models can guide production more effective.

The existing process equipment design resource utilization rate in automobile industry is low, so it is urgent to change the design method to improve the design efficiency. This paper proposed a fast design method of process equipment driven by classification retrieval of 3D model-based definition (MBD). Firstly, an information integration 3D model is established to fully express the product information definition and to effectively express the design characteristics of the existing 3D model. Through the classification machine-learning algorithm of 3D MBD model based on Extreme Learning Machine (ELM), the 3D MBD model with similar characteristics to the auto part model to be designed was retrieved from the complex process equipment case database. Secondly, the classification and retrieval of the model are realized, and the process equipment of retrieval association mapping with 3D MBD model is called out. The existing process equipment model is adjusted and modified to complete the rapid design of the process equipment of the product to be designed. Finally, a corresponding process equipment design system was developed and verified through a case study. The application of machine learning to the design of industrial equipment greatly shortens the development cycle of equipment. In the design system, the system learns from engineers, making them understand the design better than engineers. Therefore, it can help any user to quickly design 3D models of complex products.

The Impact

The article discusses the concepts of information modeling and 3D modeling. The relationship between the concepts of a BIM and a 3D model is analyzed and the key differences are identified. The advantages of using a federated information model when creating complex BIM designs of processing plants are presented and compared with working in a single file. A brief overview of the existing software systems that may be used to create information and 3D models of processing plants is presented. The example of an information model design for the backfill material production shop based on the tailings of the Tominsky GOK concentrator is used to illustrate the interaction between various software packages related to the development of the corresponding sections of the 3D model (TX for the production technology, AP for the architectural solutions, QL for the reinforced concrete structures). The design algorithm used in these software packages is considered and the corresponding structural calculations are provided. The benefits and effectiveness of the corresponding software packages are described. The impact on the calculation quality and reliability, the time required for the design work, referencing between various parts of the design, the ability to search for collisions and subsequently minimize errors in the construction and equipment installation are also analyzed.

Abstract: With the continuous development of science technology, Building Information Modeling (BIM) technology has slowly garnered wider attention from designers and architecture professionals. BIM, the 3D model-based process that allows for efficient planning, designing, constructing and managing buildings and infrastructure, could potentially revolutionize the building architectural discipline. This paper analyses the significance of the application of BIM technology in architectural lighting design, as well as the application points and the trends.

Abstract In this paper, a rotational robotic arm is designed, modelled and optimized. The 3D model design and optimization are conducted by using SolidWorks. Forward kinematics are derived so as to determine the position vector of the end effector with respect to the base, and subsequently being able to calculate the angular velocity and torque of each joint. For the goal positioning problem, the PD control law is typically used in industry. It is employed in this application by using virtual torsional springs and frictions to generate the torques and to keep the system stable.

The objectives of the research were to (1) design an instructional model based on Connectivism and Constructivism to create innovation in real world experience, (2) assess the model designed–the designed instructional model. The research involved 2 stages: (1) the instructional model design and (2) the instructional model rating. The sample consisted of 7 experts, and the Purposive Sampling Technique was used. The research instruments were the instructional model and the instructional model evaluation form. The statistics used in the research were means and standard division. The research results were (1) the Instructional Model based on Connectivism and Constructivism to Create innovation in Real World Experience consisted of 3 components. These were Connectivism, Constructivism and Innovation in Real World Experience and (2) the instructional model rating was at a high level (=4.37, S.D.=0.41). The research results revealed that the Instructional Model Based on Connectivism and Constructivism to Create Innovation in Real World Experience was a model that can be used in learning, in that it promoted the creation of real world experience innovation.
