联接螺栓强度计算方法

联接螺栓的强度计算方法

一.连接螺栓的选用及预紧力: 1、已知条件: 螺栓的s=730MPa 螺栓的拧紧力矩T= 2、拧紧力矩: 为了增强螺纹连接的刚性、防松能力及防止受载螺栓的滑动,装配时需要预紧。 其拧紧扳手力矩T用于克服螺纹副的阻力矩T1及螺母与被连接件支撑面间的摩 擦力矩T2。装配时可用力矩扳手法控制力矩。 公式:T=T1+T2=K* F* d 拧紧扳手力矩T= 其中K为拧紧力矩系数, F为预紧力N d为螺纹公称直径mm 其中K为拧紧力矩系数, F为预紧力N d为螺纹公称直径mm 摩擦表面状态K值 有润滑无润滑 精加工表面 一般工表面 表面氧化 镀锌 粗加工表面- 取K=,则预紧力 F=T/*10*10-3=17500N 3、承受预紧力螺栓的强度计算: 螺栓公称应力截面面积As(mm)=58mm2 外螺纹小径d1=8.38mm 外螺纹中径d2=9.03mm

计算直径d3=8.16mm 螺纹原始三角形高度h=1.29mm 螺纹原始三角形根部厚度b=1.12mm 紧螺栓连接装配时,螺母需要拧紧,在拧紧力矩的作用下,螺栓除受预紧力F0的拉伸而产生拉伸应力外,还受螺纹摩擦力矩T1的扭转而产生扭切应力,使螺栓处于拉伸和扭转的复合应力状态下。 螺栓的最大拉伸应力σ1(MPa)。 1s F A σ= =17500N/58*10-6m 2=302MPa 剪切应力: =1σ=151 MPa 根据第四强度理论,螺栓在预紧状态下的计算应力: =*302= MPa 强度条件: =≤*=584 预紧力的确定原则: 拧紧后螺纹连接件的预紧应力不得超过其材料的屈服极限s σ的80%。 4、 倾覆力矩 倾覆力矩 M 作用在连接接合面的一个对称面内,底板在承受倾覆力矩之前,螺栓已拧紧并承受预紧力F 0。作用在底板两侧的合力矩与倾覆力矩M 平衡。 已知条件:电机及支架总重W1=190Kg ,叶轮组总重W2=36Kg ,假定机壳固定, () 2031 tan 2 16 v T d F T W d ?ρτπ += = 1.31ca σσ≈[] 02 11.34F ca d σσ π =≤
