为提高双腔颚式破碎机破碎力计算的准确性，使用速度瞬心法，分析双腔颚式破碎机偏心轴旋转360°动颚的运动规律及破碎腔的变化规律，提出有效破碎腔折算系数，并对破碎力的变化规律进行分析。结果表明，破碎力随有效破碎腔的变化呈周期性变化，修正了最大破碎力计算公式，得出双腔颚式破碎机在偏心轴转至（水平向右逆时针转起）170°时左腔破碎力达到最大值，转至350°时右腔破碎力达到最大值。对完善双腔颚式破碎机的基础理论有重要意义。
為提高雙腔顎式破碎機破碎力計算的準確性，使用速度瞬心法，分析雙腔顎式破碎機偏心軸鏇轉360°動顎的運動規律及破碎腔的變化規律，提齣有效破碎腔摺算繫數，併對破碎力的變化規律進行分析。結果錶明，破碎力隨有效破碎腔的變化呈週期性變化，脩正瞭最大破碎力計算公式，得齣雙腔顎式破碎機在偏心軸轉至（水平嚮右逆時針轉起）170°時左腔破碎力達到最大值，轉至350°時右腔破碎力達到最大值。對完善雙腔顎式破碎機的基礎理論有重要意義。

In order to improve the calculation accuracy of the crushing force of double cavity jaw crusher ,we applied the method of instantaneous center of velocity to analysis the rule of the mov-ing jaw and the change of the crushing cavity of double cavity jaw crusher with the eccentric shaft rotated 360° .Then the conversion coefficient of the effective crushing cavity was put forward , and the change rule of the crushing force was studied .The results indicate that the crushing force periodicity changes with the variation of the effective crushing cavity .It also shows that the crushing force of the left cavity reaches to maximum w hen the eccentric shafts to 170° ,and the crushing force of the right cavity reaches to maximum when the eccentric shafts to 350° .This re-search revises the formula of the max crushing force ,and perfects the basic theory of the double cavity jaw crusher .
