The invention discloses a vibration reduction and insulation device for parallel truss-type control moment gyros and belongs to the technical field of remote sensing satellite vibration reduction and insulation. The vibration reduction and insulation device comprises a control moment gyro bracket, vibration insulation rod platform installation bases, vibration insulation rod sets and satellite structure installation bases; two or more control moment gyros are all installed on the control moment gyro bracket, each control moment gyro corresponds to one corresponding vibration insulation rod set, and each vibration insulation rod set is formed by connecting two or more vibration insulation rods in parallel; one end of each vibration insulation rod of the corresponding vibration insulation rod set is connected with the end surface, not provided with the control moment gyros, of the control moment gyro bracket through the corresponding vibration insulation rod platform installation base; the other end of each vibration insulation rod of the corresponding vibration insulation rod set is connected with a corresponding satellite structure through the same satellite structure installation base; and one ends of the vibration insulation rod sets are uniformly distributed on the control moment gyro bracket, and the other ends of the vibration insulation rod sets are uniformly distributed on the satellite structures. According to the vibration reduction and insulation device for the parallel truss-type control moment gyros, micro vibration produced during working of the control moment gyros is insulated and reduced through the vibration insulation rods.
