Machine design theory
The machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and u question.
Carries on each kind of machine design work to be usually called designs the personnel or machine design engineer The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineering material, materials mechanics and machine manufacture technology has the deep elementary knowledge.
If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itlf certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of product
Must regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely rvice data and the formula is insufficient to the completely decision which makes in a good design needs. On the other hand, should be earnest precily carries on all operations. For example, even if places wrong a decimal point position, also can cau the correct design to turn wrongly.
A good design personnel should dare to propo the new idea, moreover is willing to und
ertake the certain risk, when the new method is not suitable, u original method. Therefore, designs the personnel to have to have to have the patience, becau spends the time and the endeavor certainly cannot guarantee brings
successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Becau many person of conrvativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choo originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.
Newly designs itlf can have the question occurrence which many flaws and has not been able to expect, only has after the flaws and the question are solved, can manifest new goods come into the market the product superiority. Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphasize, if designs itlf does not request to u the brand-new method, is not unnecessary merely for the goal which transform to u the new method.
In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not nd to stops up the innovation the mentality. Usually, must propo veral ts of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has ud certain not in plan some ideas which accepts.
How does the psychologist frequently discuss caus the machine which the people adapts them to operate. Designs personnelπs basic responsibility is diligently caus the machine to adapt the people. This certainly is not an easy work, becau certainly does not have to all people to say in fact all is the most superior operating area and the operating process.
