Ergonomics And Simulation In Product Design

With the advent of information epoch, higher requirement has been mentioned to product design; we should design and manufacture the product which meets our customer requirement in very short time. So the design should consider the usability, glamorization and processible in parallel. Usability means that the product should be aligned with user requirement; Ergonomics is the subject which studies how to align with usability. To fulfill the target of design a product in short time and high efficient, CAED(Computer Aided Ergonomic Design) was been introduced into product design. It is a important method to design a product and study the ergonomic in parallel by virtual technology. The design can verify the usability when he finishes the product design, Compare with traditional design method, it can reduce the design lead time and save huge amount of money. So it is worthy of being extended.The target of this theme is to explain the efficiency and advance of compute simulation design. By designing an strain of lumbar muscles recover equipment; it is approved that simulation design is efficient method.To design a effective recover equipment, we should know what is the best recover method for strain of lumbar muscles. The theme explain the reason of strain of lumbar muscles, how to cure it and find the effective exercise for it. But it is not enough to design a equipment if only know the direction of design. Especially it is nonsense if the product does not follow the ergonomics. In the theme, one recommended recover equipment is analysis by simulation, it is approved that it doesn't meet ergonomics requirement. When the new recover equipment is being designed, the effective force mode is found by biomechanics. New equipment is designed by this force mode; the equipment is also analyzed by virtue body simulation and showed it was reasonable, even more it was approved more comfortable than original method.
