hemanshu 0 Report post Posted June 18 How i can model a spring element with axial and radial stiffness in Optistruct? Please Help? As per my understanding PBUSH element have K4,K5&K6 for rotation stiffness not axial stiffness. Please explain. Thanks Hemanshu Quote Share this post Link to post Share on other sites

Rahul R 316 Report post Posted June 19 Yes K4,K5&K6 is for rotation stiffness.Please note, Rotational stiffness values are input based on rotations defined in Radians. Quote Share this post Link to post Share on other sites
hemanshu 0 Report post Posted June 19 Thanks for the reply. We want to model a composite (Rubber) hose as a spring (BUSH) element. As, hoses are cylindrical (means they have axial and radial stiffness; Best to define in cylindrical co-ordinates) and curved (Not in single Plane). So, i have to model them with multiple bush elements (Each element in different Plane; best to define in cylindrical co-ordinates). So, i want to know which bush element is most suitable for my application in cylindrical co-ordinates. Please explain the procedure to define also. I am attaching here file too showing one model as hose and one model as CBUSH (Just for explanation). Thanks Hemanshu DesignTech.rar Quote Share this post Link to post Share on other sites

hemanshu 0 Report post Posted June 20 Thankyou rahul. While defining CBUSH element in Cylindrical co-ordinates, does r refers to K1 z refers to K2 t refers to K3 or some different. Otherwise can you reply me in my model by creating CBUSH elements with axial stiffness 19680 and radial stiffness 10? Please revert. Quote Share this post Link to post Share on other sites
