- Q: What are the basic requirements for the design of mechanical parts?
- In order to improve the strength of mechanical parts, the following measures can be adopted in principle at design time:Adopt a material of high strength;Make the part have enough sectional size;The sectional shape of a part is properly designed to increase the moment of inertia of the cross section;The mechanical properties of the material were improved by heat treatment and chemical heat treatment;Improve the manufacturing accuracy of moving parts to reduce the dynamic load at work;Reasonable allocation of parts of the machine in order to reduce the impact on the parts of the load.
- Q: Does the SolidWorks mechanical design engineer paint parts individually or draw parts in an assembly?
- There are two ways, corresponding to "bottom up" and "top down" two design methods.
- 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: What are the basic criteria for the design of mechanical parts?
- (2) the demolition of the old machine parts of the work, the stress components and their connections, should meet a predetermined maximum load enough strength, stiffness and stability during normal operation should not occur due to the work cycle or stress or fatigue fracture times have broken, excessive deformation or collapse; also must considering the stability of the whole mechanical equipment under the premise of the anti overturning wind or anti slide, especially those with mechanical vibration displacement load or its expected quality uneven distribution.(3) adequate adaptability to the use of the environment. The work equipment of the demolition of the old machine parts must be used to the environment (such as temperature, humidity, air pressure, wind load, snow load, vibration, and electrostatic, magnetic and electric fields, radiation, dust, microorganism, animal and corrosive medium) has enough ability to adapt, especially anti corrosion or erosion, aging wear, anti-interference ability, not because the electrical components affect the physical, chemical and biological caused by accident.
- Q: Why do the design of mechanical parts (flanges and elbows) be based on the yield limit?
- When the metal material reaches its yield limit, the plastic deformation still goes on without increasing the external force. The general mechanical parts (flanges, elbows) and engineering structural parts are not allowed to produce plastic deformation, otherwise it will fail and accidents. Therefore, the design of mechanical parts (flanges and elbows) mostly takes the yield limit as the design.
- Q: Can the bearings used in the design of mechanical equipment be used as part drawings?
- Roller bearings do not have to draw part drawings. In assembly drawings, rolling bearings can be drawn in three different ways. These three methods are universal, descriptive and descriptive. The first two kinds are simplified drawing methods. In the same drawing, only one of these two simplified drawing methods is adopted. For the three kinds of law, the national standard "mechanical drawing representation of rolling bearings."
- 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,
- Q: What is the design procedure of mechanical parts urgently ah?!
- 5. assembly and parts diagram design. According to the structure and size of parts assembly sketches to determine the complete assembly and parts diagram design. (according to the plan to determine the main dimensions, structure design, parts drawing, sorting out the map) four, as the case with technical documentation requirements, design and coding machine calculation manual, manual, standard parts list, purchased parts list, etc. in the conditions of acceptance in the design process, such as a link the problem is feasible or not, need to return to revise the previous design, until the problem is solved. Sometimes, for this reason, even the whole project has to be knocked over. Therefore, the mechanical design process is an iterative process. (standard and outsourcing parts arrangement, specification preparation, acceptance documents
- Q: What do engineers need to learn from mechanical design as an electronic hardware engineer?
- It is suggested that the first learn the "foundation" of precision machinery design, then study the "Electronic Electrical Engineering", if it is possible to learn the "modern metal material technology", because accurate small parts, put forward higher requirements on the properties of the materials used.
- Q: In the process of mechanical design, those areas should be designed as fillet and when to design chamfer. These materials can be found in those places, and the title of the book is also OK. Thank you!
- The edges of the non machined surfaces of various castings shall be designed as arc R, and the sharp edge of the lathe shall be chamfered 45 degrees. These are in the design manual, you are new, and when you are free, look at the design manual.
