| Abstract: | This paper has analyzed the importance of calculation about nail holding power of micron wood fiber product by mould pressing. The primary hypotheses of dynamic analyses of nail holding power have been put forward, The dynamic model of nail holding power has been established. The distribution function of thread force has been deduced. Using the theory of this paper, we can calculate the thread force quantitatively according to the rigidity of micron wood fiber product by mould pressing and the geometric parameters of screw. Further more, the nail holding power can be calculated. An important theoretical basis about calculation of nail holding power of micron wood fiber product by mould pressing has been given. |
