Analysis and verification of cable pretension effect on the buckling load of a single-link flexible mechanism

• Dynamic model of a single-link system with pretensioned cables is developed. Effect cable pretension investigated through von Kármán nonlinearity. Analytical formulation buckling load derived from dynamical modelling. Results ANSYS analysis are compared calculated results. Experimental verification link performed. This paper utilizes the extended Hamilton's principle to develop dynamic flexible mechanism two involving pretensions. The effect considered by introducing nonlinearity into Before implementing modal analysis, beam goal analyzing structural stability for pre-tensioned cables. Based on proposed model, transcendental equation determining critical derived. Several typical and materials included investigate their influence load. An alternative approach predict braced applied using concept lateral stiffness at tip, which leads same as that presented model. Finite element simulations accomplished in ANSYS. loads obtained analytical values based method, demonstrates effectiveness In addition, an approximate procedure estimating also performed basis linear relationship between Finally, experimental testbench built phenomenon identified increasing
