Q:In the mechanical design process, those areas should be designed to fillet. When will it be designed to chamfer? 10
Generally more chamfering, mainly to reduce stress concentration, easy assembly, easy to match the relative movement of parts. Most are inverted x 45 degrees, and in some places, if you want to pass O ring and some seals, it can be inverted to * 20 degrees /30 degrees angle. The fillet is much less Oh, you have to consider is mainly matched with the corresponding, both in the process of relative motion, if you feel there are steps can cause some problems such as stuck, with a smooth transition, it is better to fillet!In fact, the chamfering or rounding is mainly needed!
Q:Mechanical design, analysis of the movements of the components of the entity rhythm 150
Mechanical design, the analysis of the role of the entity rhythm, WO wrote two articles, which can be referred to you.
Q:The basic idea of mechanical parts design is briefly introduced
1, according to the requirements and conditions, determine the type of parts2, determine the parts load, select materials, formulate parts work capacity, calculate the key size;3 、 structure design;4, drawing, marking tolerances, coordination, roughness, processing requirements and technical conditions;
Q:Mechanical design practice course, let students do something
The school is a rational knowledge, but the actual application is perceptual knowledge, the two change requires a process to know from the use, this process appears simple, it is a complex process, such as simple and fitter tools: drill and tapping, need to work in the process of careful experience that is absolutely useless empty talk, feed on illusions. No matter what other enterprises, you have to come up with real technical ability.
Q:What are the basic requirements for the design of mechanical parts?
2. stiffnessThe elastic deformation of a component at work does not exceed the allowable limit. This is called the stiffness requirement. Obviously, only when the elastic deformation is too large to affect the working performance of the machine, it is necessary to meet this requirement. For this kind of parts, besides the strength calculation, the stiffness calculation must be done.
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:What kind of software is used in the design of machine parts?
No, most, only the more, the most suitable for you is your most.If you usually design only 100 of the following parts, use SOLIDWORKIf it is under 1000, using proe is goodMore than 10000, then you use CATIAAs for UG, a little embarrassed, suspended in midair.
Q:Mechanical design of various parts of the hardness value of how to determine?.
In mechanical design, you need to determine the material, strength, and wear requirements of other parts at relatively moving locations so that you can determine how to heat the parts and achieve the best hardnessIf you are testing mature products both at home and abroad, you only need to have hardness and test materials for each part
Q:Good mechanical design or good mechanical manufacturing?
The range of mechanical design and manufacturing involves relatively wide, including both mechanical manufacturing and automation;
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
