3、h2=1m。各构件质量和转动惯量分别为：m2 = 500kg, Js2 = 25.5kg·m2, m3 = 200kg, Js3 = 9kg·m2, m4 = 200kg, Js4 = 9kg·m2, m5=900kg, Js5=50kg·m2, 构件1的质心位于O1上，其他构件的质心均在各杆的中心处。D为矿石破碎阻力作用点，设LO5D = 0.6m，破碎阻力Q在颚板5的右极限位置到左极限位置间变化，如图(b)所示，Q力垂直于颚板。图(c)是四杆铰链式颚式破碎机方案简图。主轴1 的转速n1=170r/min。lO1A = 0.04m, lAB = 1.1

4、1m, l1=0.95m, h1=2m, lO3B=1.96m，破碎阻力Q的变化规律与六杆铰链式破碎机相同，Q力垂直于颚板O3B，Q力作用点为D，且lO3D = 0.6m。各杆的质量、转动惯量为m2 = 200kg, Js2=9kg·m2，m3 = 900kg, Js3=50kg·m2。曲柄1的质心在O1 点处，2、3构件的质心在各构件的中心。二、设计要求试比较两个方案进行综合评价。主要比较以下几方面：1. 进行运动分析，画出颚板的角位移、角速度、角加速度随曲柄转角的变化曲线。2. 进行动态静力分析，比较颚板摆动中心运动副反力的大小及方向变化规律，曲柄上的平衡力矩大小及方向

5、变化规律。3. 飞轮转动惯量的大小。三、机构的结构分析3.1六杆铰链式颚式破碎机六杆铰链式破碎机拆分为机架和主动件构件组成的RRR杆组，构件组成的RRR杆组。 3.2 四杆铰链式破碎机破碎机四杆铰链式破碎机破碎机拆分为机架和主动件，构件组成的RRR杆组。 四、机构的运动分析4.1 六杆铰链式颚式破碎机的运动分析（1）调用bark函数对主动件进行运动分析。见表4.1表4.1形式参数n1n2n3kr1r2gamtwepvpap实值1201r120.00.0twe pvpap（2）调用rrrk函数对由构件组成的RRR杆组运行分析。见表4.2.表4.2形式参数mn1n2n3k1k2r1r2twepvp
