Cable driven parallel robot modal analysis
I am a Ansys beginner so will be asking a lot of questions. I am about to undertake a modal analysis of a cable driven parallel robot, in particular a CDPR that is similar in structure to that of the Skycam. Skycam is the robot that films sporting events such as football games. The robot consists of four cables which are attached to a centre point (end effector) which would hold the camera. The end effector is suspended below the cables which are fixed above. A quick google search will familiarise you with the structure. I am firstly interested in finding the mode shapes and frequencies of a cable and then the whole structure. Any advice at all on how to approach the task is appreciated.
My first thoughts are to create a cable model using LINK180 elements and follow the steps outlined in this video to hopefully gain the modes of the cable.
