Q:Mechanical design, analysis of the movements of the components of the entity rhythm 150
Mechanical (machinery) refers to the general name of machines and institutions. Machinery is a tool that helps people to reduce their work difficulty or effort. Things like chopsticks, brooms and tweezers can all be called machines. They are simple machines. A complex machine consists of two or more than two simple machines. These more complex machines are usually called machines. From the point of view of the structure and motion mechanism and machine, there is no difference between general machinery.
Q:The strength criterion of mechanical parts design is briefly introduced
3. heat resistance criteria, due to friction and other reasons, when the machine is running, the temperature of the machine parts and lubricants will generally rise. Excessive work temperature will lead to a decrease in lubrication effect, and will cause thermal deformation, hardness and strength degradation of the parts, even damage. In the high temperature, metal mechanical parts may be glued and stuck; plastic and other non-metallic mechanical parts may soften, or even melt, and in some cases will cause thermal stress. Heat resistance is generally not the temperature control criterion of mechanical parts exceeds the allowable value, in order to ensure the normal work of the parts, the expression is (3 - 18) in order to improve the temperature control performance, heat dissipation, when necessary, can use water or air cooling measures. 4. vibration stability criteria, when the frequency of excitation is equal to the natural frequency of the object, the amplitude of the object is the largest, the frequency of excitation is different from the natural frequency, and the amplitude of the object is smaller. When the frequency of excitation is close to the natural frequency of the object, the amplitude of the forced vibration is very large. This phenomenon is called resonance. Vibration stability refers to the quality of mechanical components avoiding resonance when the machine is running. In order to prolong the life of the machine, in order to avoid the damage of the shaft and the machine, the vibration stability of the axle is calculated, especially the axis of the high-speed machine.
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: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:What are the main principles of mechanical principles and mechanical parts design?
7. part surface quality requirements and corrosion protection requirements;8. cost factors;......There are many other factors.
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: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:Who can provide mechanical parts design report,
Estimate is very suspended, needless to say, free of charge, that is, you go to buy, nor necessarily sell you. This is someone else's technical secret, it's not good to go inside for several years.
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:Now I'm working on mechanical design. Is a large dust equipment design.
A mechanical design is learning by doing, the school learned to pick it up, in addition to learn how to use the design manual, design experience for reference to others
