液压缸的计算 液压缸的主要尺寸包括：液压缸内径D、活塞杆直径d、液压缸缸体长度L 液压缸内径D 1根据最大总负载和选取的工作压力来确定 2根据执行机构速度要求和选定液压泵流量来确定 根据最大总负载和选取的工作压力来确定 以单杆缸为例：无杆腔进油时?D=√4F1/π(p1-p2)-dp2/p1-p2 有杆腔进油时D=√4F2/π(p1-p2)+dp1/p1-p2 如果初步选择回油压力p2=0，以上两种简化为:无杆腔进油时，D=√4F1/πp1 有杆腔进油时?D=√4F2/πp1+d 根据执行机构速度要求和选定液压泵流量来确定 无杆腔进油时：D=√4qv/πv1 有杆腔进油时：D=√4qv/πv1+d 计算得到的液压缸内径(即活塞直径)应为标准值 （二）活塞杆直径d 原理：活塞杆直径可根据工作压力或设备类型选择液压缸的往复速度比有一定要求的时候 d=D√λv-1/λv 计算所得活塞杆直径d亦应圆整为标准系列值。
（三）液压缸缸体长度L 原则：由液压缸最大行程、活塞宽?度、活塞杆导向套长?度、活塞杆密封?长度和特殊要求的 确定其他长度为了降低加工难度，液压缸体的长度一般不是?内径应大于20-30倍 缸筒壁厚δ 确定原则：中低压系统，无需校核；高压大直径时，必须校核δ 缸筒壁厚δ校核方法 薄壁缸体（无缝钢管）: 当δ/D≤0.08时δ≥pmaxD/2[б] 厚壁缸体（铸造缸体）: 当δ/D=0.08——0.3时 δ≥pmaxD/2.3[б]-3pmax 当δ/D≥0.3时 δ≥D/2[√[б]+0.4?py/[б]-1.3py-1] 液压缸其它部位尺寸的确定 导向长度H≥L/20+D/2（L为液压缸最大行程） 活塞宽度B=（0、6——1、0）D； A=(0.6—10)D（D<80mm） 导向套滑动面长度A A=(0.6—1)d（D≥80mm） 如装有隔套K时，C=H-（A+B）/2 液压缸其它部位尺寸的确定 活塞杆长度由L确定，必要时需进行稳定性验算。
当液压缸承受轴向压缩载荷时： 若l/d≤15时，无须验算 验算l/d≥15时，可按材料力学有关公式进行 90-L-075-KN-5-NN-80-R-4-S1-D-03-GBA-38-38-24 90L075KN5NN80R4S1D03GBA383824 90L075-KN-5-NN-80-S-3-C7-D-03-GBA-42-42-24 90L075KN5NN80S3C7D03GBA424224
