3、1.15m, lO5C = 1.96m, l1=1m, l2=0.94m, h1=0.85m, h2=1m。各構件質(zhì)量和轉動慣量分別為：m2 = 500kg, Js2 = 25.5kgm2, m3 = 200kg, Js3 = 9kgm2, m4 = 200kg, Js4 = 9kgm2, m5=900kg, Js5=50kgm2, 構件1的質(zhì)心位于O1上，其他構件的質(zhì)心均在各桿的中心處。D為礦石破碎阻力作用點，設LO5D = 0.6m，破碎阻力Q在顎板5的右極限位置到左極限位置間變化，如圖(b)所示，Q力垂直于顎板。圖(c)是四桿鉸鏈式顎式破碎機方案簡圖。主軸1 的轉速n1=170r/min

4、。lO1A = 0.04m, lAB = 1.11m, l1=0.95m, h1=2m, lO3B=1.96m，破碎阻力Q的變化規(guī)律與六桿鉸鏈式破碎機相同，Q力垂直于顎板O3B，Q力作用點為D，且lO3D = 0.6m。各桿的質(zhì)量、轉動慣量為m2 = 200kg, Js2=9kgm2，m3 = 900kg, Js3=50kgm2。曲柄1的質(zhì)心在O1 點處，2、3構件的質(zhì)心在各構件的中心。2.2 設計要求試比較兩個方案進行綜合評價。主要比較以下幾方面：1. 進行運動分析，畫出顎板的角位移、角速度、角加速度隨曲柄轉角的變化曲線。2. 進行動態(tài)靜力分析，比較顎板擺動中心運動副反力的大小及方向變化規(guī)律

5、，曲柄上的平衡力矩大小及方向變化規(guī)律。3. 飛輪轉動慣量的大小。三.機構的結構分析3.1六桿鉸鏈式破碎機六桿鉸鏈式粉碎機拆分為機架和主動件，構件組成的RRR桿組，構件組成的RRR桿組。21 83247 111096543.2四桿鉸鏈式破碎機四桿鉸鏈式破碎機拆分為機架和主動件，構件組成的RRR桿組。21 765432四.機構的運動分析4.1六桿鉸鏈式顎式破碎機的運動分析。1) 調(diào)用bark函數(shù)求主動件的運動參數(shù)。形式參數(shù)n1n2n3kr1r2gametwepvpap實 值1201r120.00.0twepvpap2）調(diào)用rrrk函數(shù)求、構件組成的RRR桿組進行運動分析。形式參數(shù)mn1n2n3k1
