The figure illustrates the nonpermanent connection of a steel cylinder head to a grade 30 cast-iron pressure vessel using 73 bolts. A confined gasket seal has an effective sealing diameter D of 0.9 m. The cylinder pressure is cycled between a minimum pressure of zero and a maximum pressure p, of 535 kPa. For the specifications given in the table for the specific problem assigned, select a suitable bolt length from the preferred sizes. Use Table A-17 for calculation purposes. Parameter Head thickness, A Cylinder thickness, B Value 16 mm 25 mm Internal diameter of the cylinder, C 0.8 m Gasket sealing diameter, D Bolt circle diameter, E Outer diameter of the cylinder head, F 0.9 m 1.0 m 1.1 m Bolt grade ISO 10.9 Bolt diameter, d 10 mm F E D 111 Find a suitable bolt length. Then, determine the bolt stiffness, material stiffness and stiffness constant of the joint. The bolt length is The bolt stiffness is mm. MN/m.
