Shoe Soles

On the basis of computer aided modeling technology, this paper proposes a porous structure modeling method based on Grasshopper visual programming language and Unigraphics NX (UG) secondary development platform. The finite element model of the foot was established, and then models of shoe soles with four basic porous structures of cross, diamond, star, and x were established. Each structure was set with a cylindrical radius of 1, 2, and 3 mm, and a total of 12 porous structure sole models were established. The shock absorption effect of the sole on the foot was evaluated by the deformation of the sole, the peak plantar pressure, and the peak stress of metatarsal bones. It is found that the maximum value of the sole deformation of the diamond porous sole is 4.725 mm, the peak plantar pressure is 105.1 Pa, and the first and second metatarsal peak pressures are 2.230 MPa and 3.407 MPa, which have the best shock absorption effect. It shows that the porous structure plays an important role in the cushioning of the sole. The biomechanical effects of porous soles on feet are studied by computer-aided technology and finite element analysis. This study provides a new research method for the cushioning design of shoe soles and has important reference value for the design of footwear.

Engine Crankshaft

This paper presents an integrated method, which is based on the CAD/CAE, for engine crankshaft design. A parametric modeling system of engine crankshaft is established with the CATIA secondary development tools. Taking advantage of the finite element analysis procedure of engine crankshaft strength which is programmed with ANSYS APDL programming language, the parametric loading, automatic solution and result analysis of the crankshaft strength can be realized. Integrating the parametric modeling system of engine crankshaft and the special finite element analysis procedure of the engine crankshaft strength, the three-dimensional digital model of the crankshaft can be generated rapidly. By changing the structure dimension, the crankshaft series design is achieved and the design and analysis can be improved. Therefore, it is helpful to improve the design quality and efficiency of crankshaft and shorten the design cycle.

For the high hoisting height, wide using range, tower crane is widely utilized in the architecture construction, while there are some deficiencies in the high rising architecture such as chimney, so the performance can’t exerted. By virtue of computer aided technology, the finite element static analysis of metallic structure of unconventional dedicated tower crane is conducted in this paper, and the figures of stress and displacement are achieved for the two working conditions and two structures. It is proved that the results are satisfied the requirements of stiffness and strength, and also foundation is established for the further analysis.

Recently, studies concerning motorcycle have been an overwhelming area of research interest. As an alternative to the real world assessment, researchers have utilized motorcycle simulator as a workstation to conduct studies in the motorcycle niche area. This paper deal with the development of a new motorcycle simulator named Semi-Interface Motorcycle Simulator (SiMS). Combination of Computer Aided Design (CAD) and Finite Element Analysis (FEA) software made it possible to design and simulates the motorcycle simulator’s conceptual design before being fabricated. The SiMS setup not only provides a near-to-real and immerse motorcycle riding experience on a super sport motorcycle model, but it also allows safer high speed motorcycle simulations to be conducted in a controlled environment that is portable and ergonomically easier to transport to various venues.
