Based on theory of elasticity and the failure criterion of concrete, a theoretical formula for the ultimate bonding capacity of expanding anchors is derived and simplified. 混凝土基材锥体受拉破坏是后锚固锚栓受拉的基本破坏形式,采用混凝土破坏准则和弹性力学方 法,推导了胀锚型锚栓基于混凝土基材破坏的抗拔极限承载力简化计算公式。 3)  glue bond anchor bolt 胶锚螺栓 4)  anchor bolt 锚定螺栓 5)  chain anchor bolt 链锚螺栓 6)  chain bolt 锚链螺栓 补充资料：齿轮轮齿渐开线、螺栓、弹簧autolsp源程序  一、齿轮轮齿渐开渐开线(defun c:gear(/)( setqp0 (getpoint"输入齿轮中心p0: ")m  (getreal"输入齿轮模数M: ")z  (getint"输入齿轮齿数Z: ")ha 1c 0.25a (/ pi 9)ra(/ (* (+ z (+ ha ha)) m) 2)rf(/ (* (- z (+ (+ ha ha) c)) m) 2)r(/ ( * m z) 2)rb ( * r (cos a))ri rbang 0g (polar p0 ang rb))(command "circle" p0 ra)(command "circle" p0 rf)(command "circle" p0 r)(command "line"  g)  (while (< ri ra)(setqang ( + ang(/ pi 360))ri ( / rb (cos ang))cta ( - (/ (sin ang) (cos ang)) ang)g(polar p0 cta ri))(command g))(command ) )二、螺旋源程序(defun errMsg (s)  (if (/= s "function cancelled") (princ (strcat "\nError: " s)))     ; 当命令执行时出现错误  (setvar "cmdecho" ocmdold)                                      ; 例如用户按下了CTRL + C  (setvar "osmode" osmold)  (setq *error* olderr)   ; 恢复旧的错误处理  (princ))(defun c:3Dthread (/ radouter threadpitch threadlength threadangle                    ptStart innerdiafactor radmid radinner ocmdold osmold 4H 5H 6H h6 g6)   ;-------------------------------------------------------------------   ; 获取公制外径大小、螺距总长   ; 然后计算一系列几何点   ; 并且关闭对象捕捉、命令回显   ;-------------------------------------------------------------------   (setq 4H (list 0.0015 0.002 0.002 0.0025 0.003 0.0035 0.004 0.005 0.006 0.007 0.008 0.009 0.010))      (setq 5H (list 0.002 0.0025 0.003 0.004 0.0045 0.0055 0.0065 0.0075 0.009 0.010 0.0115 0.0125 0.0135))      (setq 6H (list 0.003 0.004 0.0045 0.0055 0.0065 0.008 0.0095 0.011 0.0125 0.0145 0.016 0.018 0.020))   说明：补充资料仅用于学习参考，请勿用于其它任何用途。 参考词条 ©2011 dictall.com
