Progress in wire-driven parallel suspension technologies in wind tunnel tests

The design of new aircraft highlights advanced flight performance of aircraft, and thus presents higher requirements for technologies for model suspension in wind tunnel tests. To further extend the capability of wind tunnel tests, new intellectual wind tunnel suspension technologies are in imperative demand. The wire-driven parallel suspension system is a new mechanism based on parallel robotic technologies with the advantages of larger stiffness and better dynamic properties. This paper gives a comprehensive review of application of wire suspension systems in wind tunnel tests, and a dynamic analysis of the systems. According to different constraints of wire-driven parallel suspension technologies, they are classified into redundantly constrained and under-constrained suspension systems, which can fulfill forced motion and forced/free motion by actively adjusting the wire length, respectively. Then, the key scientific technological issues and advances of both systems are expounded. It is noted that wire-driven parallel suspension technologies are expected to become more reconfigurable and intellectual in the future. Our study can provide guidance and reference to application of wire-driven parallel suspension technologies in wind tunnels.
