Abstract

The invention relates to an aircraft mechanical arm and a manufacturing method thereof, and in particular relates to an aircraft mechanical arm based on shape memory polymer and dielectric elastomer and a manufacturing method thereof, aiming at solving the problems that an existing astronautic mechanical arm is complicated in structure and relatively high in requirements on transportation and work environment, and is easily damaged and the transport capacity is wasted due to heavy weight. The aircraft mechanical arm comprises a first base, a second base, a third base, a fourth base, a dielectric elastomer cylinder and two stretching assemblies, wherein each stretching assembly is in a cuboid which comprises four shape memory polymer panels; the first base is connected with the second base through one stretching assembly; the second base is connected with the third base through the dielectric elastomer; the third base is connected with the fourth base through one stretching assembly; and the four directions of each end surface of the dielectric elastomer are coated with electrodes. The aircraft mechanical arm based on shape memory polymer and dielectric elastomer belongs to the field of aircraft machinery.

Description

technical field [0001] The invention relates to an aviation mechanical arm and a manufacturing method thereof, in particular to an aviation mechanical arm based on a shape memory polymer and a dielectric elastomer and a manufacturing method thereof, belonging to the field of aviation machinery. Background technique [0002] The Canadian robotic arm officially debuted in the STS-2 mission in 1981. The space shuttle has used the Canadian robotic arm on more than 50 missions. As the pioneer of the space manipulator, the Canadian manipulator has shown the wide range of use and great development potential of the manipulator, which has greatly promoted the development of the space manipulator. Since then, the US and Soviet space station designs have space station manipulators, especially The famous Space Station Remote Manipulator System (SSRMS) on the International Space Station played an indispensable role in the construction, maintenance, supply and use of the space station aft...
