摘　　要：从理论上分析了新型复摆颚式破碎机3种不同的机构模型简化方法,在不同简化模型下,能够获得动颚边板上10个测试点的理论运动轨迹。通过对测试点理论运动轨迹与实测运动轨迹特征参数的比较,表明线接触高副机构能够很好地反映实际模型变长连杆的特点,且实际模型比传统铰链四杆机构更为接近。对新型颚式破碎机进行运动学、动力学分析进行机构简化时,建议采用线接触高副模型进行机构分析,减小机构简化带来的误差,提高动力学分析的可靠性。Three different simplified model of the mechanism for the new single toggle jaw crasher are analyzed in theory. And the kinetic track of the ten test - points which situate in the side - board of the moving jaw, can acquired easily under the different models. Compared the characteristic parameters of the track of the test - points between the actual track and the theory tracks,the line - contact surfaces mechanism can reflect well the actual model＇s characteristic that the actual model has a changed link - bar in length. The dynamic analysis of the crusher is analyzed in virtue of the line - contact surfaces mechanism and the analysis can reduce the analytic error.
