分析微米木纤维模压制品握钉力计算的重要性，提出其握钉力力学分析的基本假设，建立其握钉力计算的力学模型，推导螺纹牙受力的分布函数。应用本文提出的理论，可以根据微米木纤维模压制品的刚度和螺纹的几何参数定量计算螺纹牙受力分布，进而计算其握钉力，为微米木纤维模压制品握钉力计算提供重要理论依据。
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 pressingand the geometric parameters of screw．Further more，the nail holding power can be calculated．An important theoretical basisabout calculation of nail holding power of micron wood fiber product by mould pressing has been given．
