Bolts

SPK Bolt calculation according to VDI 2230, Sheet 1, 2015 and Sheet 2, 2014
Single bolt with axial and shearing force
Cylindrical flange connection
General connections with user-defined hole pattern (Sheet 2)
Calculation according to input FEM results (Sheet 2)
Taking into account the temperature differences
Rights: M04, M04a, M04b

High strength bolting modules

Bolt rating along VDI2230, configurations

• Connection under axial load only
• Connection under axial and shear load
• Flange type bolted connection
• Arbitrary bolting pattern
• Import of FEM results for loading condition
• Sizing function for bolt length and bolt diameter

Bolt, nut and washer types

• Own bolt geometry definitions
• Own nut and washer definition
• Washers: ISO 7089, ISO 7090, ISO 7093-1, ISO 7093-2, ANSI / ASME 18.22.1, own definition
• Nut: ISO 274, DIN EN 2432, DIN EN 24035, DIN EN 28673, DIN EN 28675, ANSI / ASME B.18.2.2, own definition
• Bolt: ISO 4762, ISO 4014, ISO 4017, ISO 1207, ISO 8765, ISO  8676 and others
• Strength classes, 8.8, 10.9, 12.9, A1…A5, SAE J492, own definition
• Extension sleeves under bolt and nut

Tightening

• Considers different tightening procedures
• Considers pre-tension loss
• Considers friction in thread and under head / nut

Temperatures

• For low and high temperatures
• Considers assembly temperature, temperature of bolt and temperature of clamped parts

ANSYS Integration

• KISSsoft integrated in ANSYS by CADFEM
• Calculate bolt loads in ANSYS and perform strength rating along VDI 2230 based on KISSsoft
• For arbitrary bolting patterns, considering clamped parts elasticity
