Modern mechanical design technology
mechanical design plays a very important role in engineering design. Looking forward to the development prospect of modern mechanical design technology is undoubtedly an important topic we care about and study. At the same time, only on this basis can we put forward reasonable suggestions for the planning and development projects and key technologies of mechanical design. Modern design technology mainly includes: excellent performance design basic technology, competitive advantage creation design technology, life cycle design technology, green product design technology, etc. The following will be introduced respectively. Excellent performance design basic technology
this is a design technology aimed at improving the comprehensive performance of mechanical products. At the same time, it is also proposed on the basis of traditional performance design. On the premise of material, structure and size design of machinery and its parts, a series of scientific research achievements such as friction and fracture mechanics are used, from individual design to system design, And expand the connotation and extension of this design technology from the depth and breadth. Its content includes the following design technologies:
reliability design and experimental technology: This is an applied engineering technology that integrates the achievements of many disciplines and takes solving product reliability as the starting point. It studies the fault causes, elimination and prevention of products and systems. Anti fatigue fracture design technology: it is a science to study the damage resistance of materials and structures in various working environments under the action of alternating external factors such as load, electric field, temperature, etc.
system dynamic design technology: this technology is to analyze, evaluate and design the dynamic characteristics of the structure, such as natural frequency, vibration mode, dynamic response, motion stability, etc., so as to ensure that the structural system can still maintain good dynamic performance and working state and have sufficient stability when it is subjected to various expected transient loads and environmental effects in the working process. Tribological design technology: this technology is an edge discipline based on engineering mechanics, fluid mechanics, rheology, surface physics and surface chemistry, comprehensively utilizing the research results of materials science and Engineering Thermophysics, and taking numerical calculation and surface technology as the main means. Its basic content is to study the friction, wear and lubrication of engineering surfaces. Anti corrosion Design Technology: its basic contents include: the selection of materials and the formulation of processing and manufacturing processes; Anti corrosion structure design and strength design; Selection and design of anti-corrosion methods; The expected life probability of the equipment and the prosperous market of the manufacturer provide customers with a more economical and practical reliability analysis of the experimental machine.
condition monitoring compensation and control technology: this technology uses physical and chemical detection and analysis methods to quantitatively detect and analyze various parameters of mechanical products in the running state, so as to make a correct judgment of the cause and location of the fault.
competitive advantage creation and design technology
this is formed and developed under the market economic system in which the types of equipment used in different fields will vary. Competition mechanism and the relationship between supply and demand are the two major characteristics of market economy, which requires production designers to use new ideas, new principles and new functions to design new products that constantly meet the needs of customers, so that enterprises will always be in an invincible position in the fierce global competition. This item includes the following design technologies:
Product Innovative Design Technology: in terms of design, this technology can generally be divided into three categories: adaptive design, variant design and creativedesign. Among them, innovative design is a technical process that aims at new or predicted needs, starts from known and practical theories and technologies, makes full use of creative thinking, conceives and designs new things that were not available in the past. Cost reduction design technology: also known as cost oriented design (DFC), it is a design technology that improves product economy and strengthens competitive advantage by reducing costs on the premise of ensuring function and quality. Practice has proved that more than 70% of the product cost depends on the design. Therefore, reducing and optimizing product costs has become the key to the success of the development and design of many electromechanical products.
rapid design technology: due to the dynamic variability of the market, the time of putting products on the market has increasingly become an important factor determining the competitiveness of products. Rapid design technology is the general name of all design technologies that apply modern science and technology such as microelectronics, information and management under the guidance of modern design theories and methods, in order to shorten the product development cycle.
simulation and virtual design technology: computer simulation technology is a comprehensive technology that uses computers as tools to establish actual or associative system models and dynamically run (Experiment) the models under different conditions. In recent years, the emerging and rapidly developing high and new technologies, such as computer simulation modeling, cad/cam and advanced technology demonstration and verification, visual computing, remote control machine and computer art, all have a common demand, that is, to establish a more real and convenient input and output system than the existing computer system, so that it can be connected with various sensors to form a more friendly multi-dimensional information environment of human-machine interface. This environment is computer virtual reality system (VRS), and the technology engaged in design in this environment is called virtualdesign (VD). Intelligent design technology: due to the lack of reasoning and decision-making ability of human designers, traditional CAD systems can no longer meet the requirements of design process automation. Therefore, the theoretical research and application practice of intelligent CAD (ICAD) came into being. ICAD system not only has good quality and high precision of traditional CAD system to detect good product numerical calculation and graphics processing ability, but also has knowledge processing ability, which can provide intelligent computer support for the whole process of design and host with obvious distinction. Intelligent design is the research on the theory and application of intelligent CAD. Generalized optimization design: it mainly extends the research of simple optimization algorithm in the traditional optimization process to the establishment and processing of models from the perspective of methodology
