Safely apply guideline VDI 2230 Sheet 2
Main focus
- Verification and calculation of highly stressed multi-bolt connections according to VDI 2230 guideline
- Loads on a bolt array - effects and findings
- Tightening and assembly methods - influences and processes
- Securing multi-bolt connections - significance and findings
On the subject
The VDI 2230 Part 1 guideline has become established worldwide in mechanical engineering for the design and calculation of individual bolted connections and requires knowledge of the load variables.
Increasing competitive pressure determines the creative process, the design and the resulting design of components and assemblies. More and more frequently, design can no longer get by with a simple screw connection. The challenge is to harmonize all external influencing factors while taking safety and costs into account.
The focus of the design and calculation of multi-bolt connections is on determining the load distribution and that of the most heavily loaded single-bolt connection. Using VDI 2230 Sheet 2 and the insight of different analytical approaches and the use of FEM systems, the most highly loaded individual bolted connection is determined quickly and reliably.
Objective
The seminar deals specifically with the VDI 2230 Sheet 2 guideline. You will gain an insight into the design and determination of forces in bolt fields in accordance with the guideline. Using practical examples, you will learn about and assess the special features of determining forces and the relationship between VDI 2230 Sheet 1 and Sheet 2.
Experience a direct comparison and the typical procedure using an FEM system. Learn how to correctly classify and evaluate the differences to other calculation tools. After the seminar, you will be able to optimize your designed components with regard to the creative design phase and the associated process effort.
