About this Webinar
Are you a compressor manufacturer striving for more accurate and reliable dynamic analysis results? One of the most critical—and often underestimated—factors in pulsation and mechanical stress studies is the accurate modeling of support stiffness. In reciprocating compressor systems, the way supports are modeled can dramatically influence the predicted natural frequencies and stress levels of your piping and compressor packages, directly impacting reliability and compliance with standards like API 618.
Key Learnings
- Why Support Stiffness Matters: Discover how support stiffness affects the mechanical natural frequencies of compressor piping systems, and why this is essential for avoiding resonance and excessive vibration—key concerns for compressor reliability and longevityÂ
- Advanced Modeling Techniques: From simplified rigid supports to detailed FEA sub-structuring, learn how to select and implement the right approach for your compressor packages. We’ll demonstrate how integrating structural steel and realistic support flexibility can shift resonance frequencies and help eliminate fatigue risksÂ
- Practical Software Demonstrations: See live examples using BOSpulse and Caesar II, showing how to incorporate support stiffness into your stress and pulsation models. Compare the impact of different support modeling options—rigid, flexible, and integrated steel—on your analysis results.
- Real-World Impact:Â Understand how accurate support modeling can help you demonstrate clear separation between compressor excitation frequencies and piping natural frequencies, ensuring compliance and reducing the risk of costly failures.
Who Should Watch
This session is for: compressor package designers and engineers, reliability and vibration specialists, and in general anyone involved in the mechanical or pulsation analysis of reciprocating compressor systems.
