Single-degree-of-freedom flapping-wing mechanism capable of simulating spatial motion track

Abstract

The invention discloses a single-degree-of-freedom flapping-wing mechanism capable of simulating a spatial motion track. The single-degree-of-freedom flapping-wing mechanism comprises a supporting frame, a transmission system, a frame and two sets of space four-bar mechanisms, wherein the frame is fixedly arranged on the supporting frame; the transmission system is arranged on the supporting frameand the frame; an output shaft is fixedly arranged on the frame; the transmission system drives the output shaft to rotate through gear transmission; two sets of the space four-bar mechanisms are symmetrically arranged at two ends of the output shaft; each space four-bar mechanism comprises a crank, a connecting bar and a rocker bar; one end of each crank is fixedly arranged at one end head of the output shaft; the other end of each crank is connected with a connecting bar through a steering universal joint; one end of each rocker bar and a connecting bar form a revolute pair; the other end of each rocker bar is a free end; meanwhile, each rocker is connected with the frame through a ball pair. The single-degree-of-freedom flapping-wing mechanism provided by the invention has simple structure and high transmission efficiency, and can realize simulation of the 8-shaped spatial motion track of insect wings under the condition of single-degree-of-freedom driving.

Description

technical field [0001] The invention relates to a flapping-wing mechanism of a flapping-wing aircraft, in particular to a single-degree-of-freedom flapping-wing mechanism capable of realizing a space movement track. Background technique [0002] The wingspan of the micro-aircraft is within 15cm, the weight is not more than 100g, the flight speed is 10-20m / s, and the flight time is 20-60min; it should have real-time imaging, navigation and communication transmission capabilities. Obtaining enemy information and other military fields, as well as civilian fields such as post-disaster rescue, exploration and detection, and aerial photography, all have huge application prospects. [0003] Aircraft are generally divided into fixed-wing aircraft, rotary-wing aircraft and flapping-wing aircraft. The development of fixed-wing and rotary-wing aircraft has reached a relatively mature stage, but when the size of the aircraft drops to the order of 10cm, the aerodynamic performance and f...

Problems solved by technology

However, most of the flapping wing mechanisms developed at present use planar crank rocker mechanisms, which can only realize two-dimensional flapping up and down, or need to add some auxiliary mechanisms to realize multidimensional flapping wing flapping. The structure is relatively complicated, which is not conducive to flapping wing aircraft. miniaturization
