| Abstract: | The design of wheelchair shock absorption spring mechanism is based on SolidWorks software. The material of components was defined. Through COSMOS software, simulated mechanical by finite element analysis, calculated the mechanical behavior in different material or construction, selected the data and the best spring design program. The method of mechanical design via CAD reduced the correction procedure of mechanical design. After the first step of mechanical design, optimize the mechanical design plan via finite element analysis and the CAD software. The method of mechanical design reduced the step of design and enhances effieiency. |
