Q:Why do the design of mechanical parts (flanges and elbows) be based on the yield limit?
In order to reach the yield limit, it is the failure of the material to begin the elasticity, and the elastic-plastic stage has been started. This is designed according to GB150-1998. You can look at the analysis data of the blasting process of the steel
Q:What is the design procedure of mechanical parts urgently ah?!
The technical design includes the following work: 1. kinematic design. According to the design scheme and the working parameters of the working mechanism, the dynamic parameters of the prime mover, such as power and speed, are determined, and the size and movement parameters of each component are determined. 2. dynamics calculation. According to the result of kinematic design, the load acting on the part is calculated. 3. part design. According to the load and design criterion of parts, the basic dimensions of parts are determined by means of calculation, analogy or model test. 4. overall assembly draft design. According to the basic dimensions of the components and the structure of the mechanism, the overall assembly sketch is designed. On the basis of considering the assembly, adjustment, lubrication and processing technology of parts, the structure and dimension design of all parts are completed. Determine the parts of the structure, size and parts of the relationship between the location, you can accurately calculate the role of the load on the parts, analysis of factors affecting the work capacity of parts, such as stress concentration. On this basis, the main parts should be checked and calculated, such as accurate calculation of shaft strength, life calculation of bearings. According to the result of calculation, the structure and size of parts can be modified repeatedly until the design requirements are met.
Q:How to judge parts in mechanical design and how to judge components?
The part is a processing unit, is processed. Parts of component is the moving unit. Mechanism is to achieve complete movement of the unit. For example, bicycle chain is composed of many parts (chain, pin, etc.) is a chain sprocket component; parts, but to "the pedals and sprocket" together, and form component. Several components constitute a chain drive mechanism. Similarly, key parts.
Q:In the design of machine parts, how to choose the matching of bearings, what should be paid attention to when assembling?
According to the performance requirements of parts, the accuracy grade of bearings and the matching accuracy of shafts and bearings are determined
Q:Mechanical design, manufacture and automation, 60
I also studied mechanical design, manufacture and automation,. Generally speaking, this job covers a wide area. Depends on what direction you want to develop, mechanical and Electrical Engineering (mechanical and electrical integration), mechanical engineering, mechanical design, etc.. Today's designers are more comfortable with people who can make drawings into models, and see their own personal interests. Character.
Q:Mechanical design of various parts of the hardness value of how to determine?.
You send out the request and I'll help you get it! Upstairs answer obvious mistakes, such as 45 steel, the best performance in 39-44HRC, but domestic heat treatment and foreign heat treatment level there are differences, the same hardness, foreign countries are several times more durable than the domestic!
Q:Mechanical manufacturing technology.
Learn tyrants thing in the community are not practical, in the factory to consider a lot of factors, not necessarily good! Encouraging a pa! Or go to the society to study well!
Q:The strength criterion of mechanical parts design is briefly introduced
1, the strength criterion requires that the working stress of the mechanical parts should not exceed allowable stress [Sigma]. The formula is typical: (3-16) lim - ultimate stress of brittle materials by static stress on the ultimate strength, the static stress of plastic materials, the yield limit of zero stress the fatigue limit. S - Safety factor. 2. stiffness criteria mechanical components are subject to elastic deformation when subjected to load. Stiffness is the ability to resist deformation of materials, mechanical parts, or structures subjected to external forces. The stiffness of the material is measured by the external force required to produce the unit deformation. The stiffness of a mechanical part depends on its modulus of elasticity, E or shear modulus, G, geometry and size, and the form of external forces. It is an important work in mechanical design to analyze the rigidity of mechanical parts. For some parts that need to be strictly deformed (such as wings, machine tools, spindles, etc.), stiffness analysis is necessary to control the deformation. We also need to control the stiffness of the parts to prevent vibration or instability. In addition, a spring, such as a spring, must be used to control its stiffness to a reasonable value to ensure its specific function. The stiffness criterion is that the elastic deformation of a component subjected to load is not greater than the allowable elastic deformation. The expression of the stiffness criterion is (3 - 17) y is an elastic deformation quantity, such as deflection, longitudinal elongation (shortening): [y] is the corresponding allowable elastic deformation. The elastic deformation of a part can be obtained by theoretical calculation or by experiment. The allowable deformation depends on the use of the part, and is determined by theoretical analysis or experience.
Q:Is the design of non-standard automation good or the design of mechanical parts? Five
The design of non-standard automation is promising, and the work of the CAD draftsman is only a small part of the non-standard automation work.
Q:At the time of mechanical design.
A part of an assembly drawing. If it is a standard part, fill in the name of the part and the standard code. If it is a nonstandard part, fill in the part name and the code specified by the company.As you mentioned, it should be the standard staff who can only fill out the part code, which is the code number specified by your company. Drawing design, the non-standard parts using the company's parts code.
