MDESIGN Seminar
Bolted connections
- design, selection & optimization
The online seminar on the calculation of bolted joints in accordance with VDI 2230 Sheet 1 teaches you in a practical way how to calculate, safely design and optimize bolts efficiently. The training contains everything you need to know about the application of VDI 2230 and other relevant standards.
These topics await you...
You will gain an overview of the importance of load-bearing capacity,
design and assembly in the calculation of bolts and learn
everything you need to know to optimize the design of your screw connections.
Precisely calculating the strength and load-bearing capacity of bolted connections
is just as relevant as avoiding typical sources of error.
Other important topics covered include
Preload force, tightening torque, consideration of material
material properties and much more.
Contents & details
Calculations:
Calculation stepsR0 to R6 according to VDI 2230 Sheet 1
- Nominal diameter
- Tightening factor (torque-, angle- and yield point-controlled tightening methods)
- Pressure, loads due to shear forces/moments
- Operating force, bolt force and force ratio
- Preload losses (setting and temperature dependencies)
- Calculated and permissible mounting preload force
Security:
StrengthVerification with the aid of calculation steps R7 to R13 and examples
- Safeties against yielding (maximum bolt force, torsional moment)
- Safety against fatigue fracture/time resistance
- Safety against excessive surface pressure
- Screw-in depth (maximum tensile forces)
- Safety against sliding and shearing (available residual clamping force)
- Tightening torque (influence of friction and lubrication)
- Constructive measures and design rules
- Examples from the VDI guideline
- Practical part I with MDESIGN bolt
