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 it the first overall drawing, or first out parts drawings, and then assembly?: Take out the part drawings first and then assemble them into a whole picture

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:What are the main functions of CAE software commonly used in the design of mechanical products or parts?: Finite element analysis, structural motion analysis, interference checking, dimensional chain analysis.

Q:In the design of large machinery, it is to design the parts first, the assembly drawings as well: This is the principle of the overall design process must go through to all aspects of the details, then how do you draw can use computer aided design. Now more flexible. If according to the traditional design from the general to the sub structure, clear whatever you draw.

Q:How to design the common mechanical parts with CATIA, and how to solve the problem when the units are inconsistent?: Very simple. Write the value / conversion value of the drawing in the parameter

Q:Can the bearings used in the design of mechanical equipment be used as part drawings?: (4459.7 GB/T 1998) for the following provisions: (1) the basic regulations and general characteristics of drawing, drawing, drawing in the various provisions of symbols, rectangular wire frames and contour lines are drawn with thick lines. When drawing a rolling bearing, the size of the rectangular frame and the outline of the outer frame should be consistent with the shape dimension of the rolling bearing (found in the manual) and the same proportion as the drawing. In the cutaway view, when drawing the rolling bearings by the universal drawing and the characteristic drawing, the section symbols (section lines) are not drawn. When drawing with the prescribed drawing method, the rolling body of the bearing does not draw a section line, and each ring can be painted in the same line section with the same direction and spacing, as shown in Figure a. Such as bearings with other parts or accessories (such as eccentric sleeve, tight sets, retaining rings, etc.), the profile line should be in line with the ring profile in different directions or different intervals, as shown in Figure B. Omission is not allowed in drawing without misunderstanding.

Q:Who knows what the design criteria for machine parts are, and how they are designed?: 5. life standards, in order to ensure that the machine in a certain life span of normal work, in the design of mechanical parts, it is necessary to request the life of mechanical parts. It should be explained that parts can be replaced during the life of the machine, that is, the life of some mechanical parts is shorter than the life of the machine. The life of mechanical parts is mainly affected by fatigue, wear and corrosion of materials. In order to avoid failure caused by parts fatigue, such as fatigue fracture, fatigue strength should be calculated according to the fatigue limit corresponding to the life of mechanical parts. That is to say, according to the requirements of life and the specific speed of parts, according to formula (3-6), the fatigue limit is calculated when the stress cycle number is N. Then the strength condition is calculated and the fatigue strength is calculated. When the fatigue strength is satisfied, the stress cycle times of the mechanical parts can be guaranteed before the damage. Wear is usually unavoidable. Under certain conditions, corrosion is inevitable, such as structural members of bridges, corrosion of buried steel pipelines, etc.. In the design, mainly to ensure the mechanical parts in life, not excessive wear and corrosion. The mechanism of wear is still fully mastered, and there are many factors affecting wear. Generally, the wear resistance of friction pairs is improved according to the tribological design principle. The main measures are as follows: reasonable selection of friction pairs, reasonable choice of lubricant and additives, and control of the working conditions of friction pairs, such as pressure, sliding speed and temperature rise. So far, there is no practical and effective method for calculating corrosion life

Q:I would like to open a small mechanical design company (specializing in the design of mechanical parts, etc.) can you make money?: I really heard about this kind of company. Key: business promotion, design experience, additional experience.If you can get enough money, if you open the advertising skills and experience in mechanical design, powerful enough if you can tell the customer to design the end where I can get a good and where can I find a cheap and can ensure the processing precision and efficiency of the manufacturers, do it.On the contrary, think twice!

Q:What software is best for designing mechanical parts?: Solid Edge software devaluation, 3D significant effect, faster to use.I have used the above three software, deep understanding. They are excellent mechanical drawing software.
