[0030] Example 1:
[0031] Such as Figure 1-4 As shown, the present invention is a variable rotation equivalent inertial mass damper, including a main energy consumption element, a translation / rotation conversion device, a planetary gear set transmission device, a secondary energy consumption element, a cylindrical rotating mass 1, control Circuit, working state circuit, left sleeve 8 and right sleeve 25 are composed. Said translation / rotation conversion device includes a screw 9, a ball nut 10 and a thrust bearing 4;
[0032] The left sleeve 8 is equipped with a planetary gear set speed change device, a secondary energy consumption element and a cylindrical rotating mass 1; the cylindrical rotating mass 1 is fixed between the left sleeve inner tube 20 and the left sleeve outer tube 8 by using a roller 6. A tooth mark 13 is made in the part near the right end. The inner cylinder of the left sleeve is provided with a secondary energy consumption element and a planetary gear set tr...
