The design of insulating glass equipment should go through product market survey, demand analysis, production conditions and cost-benefit analysis, complete the overall design report, determine the implementation plan, and carry out the detailed design process after the evaluation and verification procedures.
In the design process of the product, the following work should be done carefully: 1) identify the key problems of the design technology by analyzing the design task requirements; 2) determine the solution and technical route for the technical difficulties; 3) determine according to the functional structure analysis Overall mechanical plan; 4) Conduct design review, complete the design according to the evaluation results, and complete the design task.
The overall design report should include the preliminary design of the principle plan design and the structural plan. The designer should conduct a comprehensive analysis of the design task requirements, determine the overall plan by comparing the choices, form the overall design report, and conduct the review. After the implementation plan is determined, detailed design calculations and structural design are carried out, and the design results are expressed in the design juice calculation specification and the specified drawings, and delivered to the manufacturing. The resulting design documents are detailed and meet process and maintenance requirements.
The design work should fully reflect the sociality of the design goals, the diversity of design schemes, the comprehensiveness of engineering design, the constraints of design conditions, the integrity of the design process, the innovation of design results and the advancement of design methods. The advancement of science and technology has provided more and more technical means and methods for designers without insulating glass equipment. Mechanical engineering design also has its own characteristics and scientific laws that must be followed; only master the design rules and advanced design methods, fully Only with ingenuity can the design task be completed satisfactorily. The following is a brief introduction to several common design methods.
(1) Mechanical system design method
The mechanical system design is sufficient to study the various parts of the system and its internal connections, starting from the overall system, constructing the basic design principles, and dialectically solving a design method for the juice problem. The main idea of ​​the system design method is to emphasize the relationship between the internal and external environment of the system in the design process, emphasizing the relationship between the overall system and the subsystem, and running through the entire design process. In the decomposition and synthesis, the strength of the liaison relationship of each subsystem and its integrity with the overall system should be considered.
(two) optimization design method
The optimization design method is a design method that solves the practical problem by applying the principle of mathematics optimization. For the vegetable-design task, the design requirements are reasonable, the work performance is better, the cost is lower, etc., and the values ​​of the main design variables are determined in various schemes, multiple sets of parameters, and multiple design variables. Excellent design requirements. In mechanical design, the optimization design is reflected in the determination of the transmission design and the determination of the preferred design parameters.
When optimizing design, first of all, we need to have a deeper understanding of the specific engineering problems, choose the optimization calculation method, construct the appropriate mathematical model, find the better design results, and find the better design parameters. For example, in the design of the reducer, the material can be more economical and the structure is compact as the design target. In this way, in the transmission design calculation. Care should be taken to select the heat treatment workers reasonably. When selecting the parameters, try to make the strength of each part reasonable. Using an optimized design approach can speed up the design process, shorten the design cycle, and achieve the goal of getting twice the result with half the effort.
(3) Reliability design
Reliability refers to the ability of the system to perform specified functions under specified conditions within a specified time. The reliability of the product needs to have a quantitative expression, but the quantitative representation of reliability has random parts. For any product, there is a time uncertainty between its reliable work and failure; therefore, for different types The reliability problem requires different expressions, such as reliability, failure-free rate, failure rate, and mean time between failures. Reasonable planning and distribution of the reliability indicators of each part can give full play to the design advantages of each part to ensure that the products reach high quality in terms of work quality, technical standards and safe use.
The concept of reliability is commonly used in the design of insulating glass equipment. For example, the safety factor used in calculating the available stress in the gear design is related to the design reliability. The life of the rolling bearing is generally taken as the number of times or time when the reliability is 90%.
For the system, the overall reliability is guaranteed by the reliability of each part. The use of standard parts, common parts, simplified part structure, and reduced number of parts are all ways to improve reliability.
(4) Tribology design
Tribology is a science that studies friction, wear and lubrication, and involves many disciplines such as materials, chemistry, and fluid mechanics. Designed according to tribological principles and methods is called tribology design. Statistics show that about one-third of global energy production is consumed by friction. 80% of mechanical parts failure is related to tribological problems, and tribology design plays an important role in industrial production.
Mechanical systems have two types of design clutches, brakes, and belt drives that utilize friction and minimize friction to reduce wear. Typical applications for the latter are plain bearings.
(5) Reverse design
Reverse design is a design method to update product quality based on the experience of existing insulating glass equipment design. Reverse design can be divided into two stages, namely, using, digesting, absorbing similar products and applying new technology innovations to design new products suitable for specific conditions. Reverse design has played a very important role in the technological advancement of some countries. For example, after the Second World War, the economic situation of a country was close to that of 瘫痪. In 1945-1970, it was asked to invest 6 billion U.S. dollars for 2-3 years, which is equivalent to 1% of the self-development cost and 1/6 of the self-development cycle. It has absorbed the technical products of many advanced countries, researched and developed them, developed special technologies, and made its products break through the level of some countries in Europe and America. After more than 30 years, it has become a world economic power.
The reverse design process generally undergoes several stages of reverse analysis, innovative design, and product trial production, and can be implemented in parallel with the imitation design, the deformation design, and the adaptive design of the needle.
(6) Innovative design methods
The mechanical design of insulating glass equipment is the process of thinking and realization to achieve the intended design goals, and the design products should be innovative. Therefore, designers should have good professional skills and broad knowledge horizons, in order to learn from the experience of the predecessors, to innovate, to obtain design results in line with design standards and innovation, innovative design is to adopt new technical principles, technical means in the design, Unconventional design processes and methods are designed to improve the technical and economic content and market competitiveness of the product.
Commonly used innovative design methods are: intellectual motivation method, biomimetic transplantation method and system search method.
(7) Other design methods
Today's science and technology is developing rapidly. In order to meet the various needs of society, many new design theories and methods have been produced, such as parallel design, computer-aided design, three-dimensional design, virtual design, intelligent design, similarity design, ergonomics, etc. . All of these design methods are characterized by systemic, social, creative, intelligent, digital and more optimized, with the goal of quickly obtaining high-tech economic value.
