Optimization and Innovation of Screw Joints of Micron-Wood-Fiber Molded Products

Micron-wood-fiber molded products are new kinds of high strength man-made wooden products. They are innovative products among molded fiber products nowadays. This paper studied a new method to design their screw joints using optimal design. It has combined the optimal design with reliability design ingeniously. The CAD programming method was put forward, which can optimize the structural parameters of micron-wood-fiber molded products, and may be used on the strength design and the check of innovation for new products. The new calculating method and software had provided effective design method for screw joints of micron-wood-fiber molded products. It would increase the calculating efficiency and precision greatly.
