Mechanical articulated arm installation method for the largest equipment of the spacecraft sealed cabin

The structure of manned spacecraft is sealed cabin, the passage of which is narrow. Installation location of the largest equipment in cabin longitudinal depth and transverse width, it is difficult to install the largest equipment. First, the best installation path is obtained by simulating the joint position. Reach to the installation position with mechanical articulated arm, through small hanger flexible installation the equipment. After experimental the results show that the method can complete the largest equipment installation of narrow space in sealed cabin, position adjustment work is finished by only one person, equipment installation work is finished by two people, is superior to traditional methods. This method can offer reference for similar installation conditions.
