What do you think is the most important thing to pay attention to in mechanical design? Personally, I think the functionality and reliability of machinery, as well as its manufacturability, are quite important. What do you all think? This post was last edited by SHISHOUHUA on 2008-8-1 02:32]
The functionality and reliability of machinery are the most fundamental requirements, while processability is also relatively important. In terms of part design, standard components should be used as much as possible to reduce costs. Material selection, in addition to considering functional reliability and manufacturability, must also be taken into account in conjunction with related mating parts. (For example, the hardness of a standard set is usually lower than that of the shaft.) Of course, cost also needs to be taken into consideration.
For what kind of equipment, what considerations should be taken? For ordinary equipment, reliability and cost-effectiveness are key factors to consider. For more expensive equipment, advanced manufacturing processes and high reliability should be given priority, with cost being considered last
In mechanical design, it should be kept in mind that fulfilling functions is the foundation； Ensuring safety is fundamental. Secondly comes the manufacturability ； Economic cost-effectiveness ； User-friendly design ； Ease of maintenance ； Aesthetics of the appearance, and so on.
On the basis of implementing the process, strive to minimize costs. What is encountered most often are things like steel and refractory materials. Heat-resistant steel is used sparingly; in many cases, it is the client who specifies the material requirements, and there’s nothing that can be done about it.
While meeting the process requirements, efforts should be made to achieve standardization, economic efficiency, ease of operation and maintenance, as well as practicality and aesthetics.
The brother who died at work a few days ago showed that safety should come first; please organize this post
1. Flexibility in installation. 2. Fit of dimensional tolerances. 3. Maintenance should be convenient. 4. The power of the motor and the reducer must be matched. 5. Reduce manufacturing costs. 6. It must comply with HSE standards
1. Be thorough and careful to avoid labeling errors. 2. The tolerances are reasonable, and the technical requirements are correct. 3. The process is reasonable. 4. Easy to process, easy to assemble, and easy to maintain and repair. 5. Simulation calculations determine the natural frequency and its relationship with the rotational frequency, in order to prevent resonance. If necessary, the design structure must be modified to avoid the resonance frequency. Ensure the safe operation of the equipment.
The functionality and reliability of the machinery are given top priority, while manufacturability is considered on a secondary basis in order to reduce costs
1. Consider costs. 2. Consider the strength of the parts and the choice of materials. 3. Pay attention to the fit between various dimensions to reduce errors
Reliability is certainly important, but practicality cannot be ignored either. The process from design to production for each piece of machinery is quite lengthy, but it ultimately starts with market demands. Regular surveys are conducted, and the material selection, required functions, appearance, size, and other aspects of the machinery are determined based on actual conditions, with continuous improvements being made during its subsequent use
Basic theories of mechanical design, design of common components, how to consult mechanical design manuals, and also learning some experience from your design supervisor
First, ensure it is applicable; if it can’t be used at all, there’s no need to discuss it further. Next, consider the costs – after all, it’s a market economy. Finally, think about installation and maintenance. It’s easy to talk about these things, but difficult to take them all into account in practice. Generally, there is a lack of on-site experience in design work; those with on-site experience usually end up in leadership roles, or else they have to retire
There are many types of mechanical design, but I will only talk about the type of mechanical design that we commonly use in our production work – namely, on-site technical innovation: 1. It can be used, and its operation is simpler and more convenient than before; it may also save effort, improve safety, or reduce costs. 2. It can be manufactured quickly; it’s best to use welded components, as this allows a few workers to complete the task, making maintenance easier and reducing costs. The only criterion to determine whether your design is successful is this: ten years later, your design is still in use. That’s what my designed baking bag is like.
First is practicality, then standards (meeting various requirements such as safety, processing, etc.) + innovation
First, the conditions must be met; secondly, cost-effectiveness needs to be taken into consideration.
Striving for simplicity, ease of maintenance, and lowest cost – these are the most crucial factors; other aspects are considered on that basis
