A bolt must be tightened enough to keep the joint compressed under all operating conditions, but not so tight that it breaks during assembly. VDI 2230 helps calculate the maximum and minimum assembly preloads based on the tightening method used (e.g., torque wrench vs. hydraulic tensioner). 3. Embedding and Relaxation (
Ensuring the bolt does not yield during tightening.
Accounts for inaccuracies in tools (e.g., torque wrenches vs. angle-controlled tightening) using the "Tightening Factor" ( αAalpha sub cap A Friction Coefficients (
Determine the minimum required clamping force to prevent joint separation or slipping. R4: Determine Load Factor (
): The portion of the external load that further stretches the bolt. Clamping Force Reduction (
For engineers and organizations worldwide, obtaining the official PDF of VDI 2230 Part 1 is an essential first step toward implementing it in a design workflow. The most reliable way to acquire the standard is through official standardization bodies and publishers, which ensure you receive the most recent and legally valid edition. The is the authoritative version, as the 2014-12 version has been superseded. Here are the official routes to purchase a legitimate copy:
For dynamically loaded joints, calculate the fluctuating stress amplitude acting on the bolt thread. Compare this against the fatigue limit of the selected bolt class to ensure infinite life or target cycle life. Step 12: Verify Surface Pressure ( pmaxp sub m a x end-sub
