Hello guys,<\/p>\n

I would like to integrate a friction spring into ANSYS Mechanical, which is not entirely untypical in industrial applications. The latter has the spring stiffness c1 (load) and spring stiffness c2 (unload), where: c1 > c2.<\/p>\n

Using a simple test model, I have already tried various variants in an APDL code block, including the non-linear spring element COMBIN39. Unfortunately, this also does not provide the desired deflection behaviour.<\/p>\n

To illustrate this, I have attached a picture in which the spring characteristic curve according to the manufacturer’s data sheet is shown on the left and a possible characteristic curve of the ANSYS spring element COMBIN39 is shown on the right. Maybe someone here has an idea how to best implement the spring characteristic shown?<\/p>\n

Thanks for your help!<\/p>\n
