beyond anything www.kiswire.com Axial stiffness (EA) In more common terms Axial Stiffness is the (non) flexibility of a rope. We calculate the stiffness or flexibility as follows : E = the apparent modulus of the rope in kN/mm 2 A = the cross sectional area of the circumscribed circle in mm 2 , based on the nominal rope diameter. 6x37 Class E modulus in kN/mm 2 is 58.86. The same in compacted version is 63.77 kN/mm 2 . For example : the EA for a 6x36WS+IWRC 76.2 mm wire rope is : 58.86 x 4560 x 10/4 = 268 MN (MN = Meter/Newton) Flexural Stiffness (EI) Flexural Stiffness is the Bending stiffness of a rope. It is calculated as follows : E = the stiffness in N/mm2 (see below table) I = the Second Moment of Area of the rope (d/6) (d is the nominal diameter) Stiffness Factors of 6x37 Class are : 6x36 (15.6) 6xK36 (18.8) 6x41 (14.5) 6xK41 (17.6) 6x49 (12.6) 6xK49 (14.4) For example : the EI for a 6x36WS+IWRC 76.2 mm wire rope is : 15.6 x 76.2 x 10/6 = 526 N/m2 The above stiffness values are due for new wire rope, with little or no load applied. Kiswire is the largest wire rope producer in the world. Annually, about 140.000 tons of wire rope is delivered, worldwide. For decades, Kiswire is specializing in the development and production of wire rope. Meanwhile, the company has acquired a reputable and leading position in a great variety of markets, in literally all corners of the world. The offshore industry is one is a main market for Kiswire since 25 years, meanwhile. Technical Data Sheet 7 E x A x 10/ 4 E x I x 10/ 6
