Analysis on the Relation between the Mechanics and the Aesthetics of Machine Structure

Along with the development of the science and technology and the change of the views of aesthetics, many novel machine structures appear, at the same time, the compatibility and the paradoxicality between the mechanics and aesthetics are placed before the machine designers. In order to improve mechanical properties of strength and stiffness in designing mechanical structure is easy to fall into misunderstanding that to improve mechanical properties depends on increasing outline dimension and the thickness of materials or selecting high performance materials. Elephantine shape, confusing alignment, incorrect size proportion and grave hue are the results of it. It is just enough to meet mechanical requirements but not ideal for aesthetic effect, increasing the cost. Conversely, it is not advisable to pursue beauty excessively or to make structure stress irrationally. This paper analysis on the harmony and contradiction between the mechanics and aesthetics of the machine, and puts forward some main measures for solving the contradiction.
