Example Embodiment
[0024] Example 1:
[0025] See figure 1 The structure of the parallel mode semi-active vibration isolator in this embodiment is:
[0026] A cylindrical upper shell 21 is provided. The rubber main spring 1 is sealed in the top opening of the upper shell 21. The main spring skeleton 3 penetrates the rubber main spring 1. The upper and lower ends of the main spring skeleton 3 are respectively provided with upper The connecting stud 31 and the lower connecting stud 32. The upper end of the upper connecting stud 31 is used to connect with the main vibrating object and transmit the vibration energy of the main vibrating object. The lower end of the lower connecting stud 32 is used to wind an excitation coil The cylindrical iron core 41 of 46 is connected, and the cylindrical iron core 41 is supported in the magnetic sleeve 44 by the shear magnetorheological elastic body 45 arranged on the outer circumference of the cylindrical iron core, and squeezes the two magnetorheological elastic bo...
Example Embodiment
[0030] Example 2:
[0031] See figure 2 The structure of the parallel mode semi-active vibration isolator in this embodiment is:
[0032] A ring-shaped rubber main spring 1 is provided. The upper shell 21 and the lower shell 22 are respectively connected with the top and bottom ends of the rubber main spring 1 to form a vibration isolator housing cavity. The upper and lower ends of the upper shell 21 are respectively fixed The upper connecting stud 31 and the lower connecting bolt 32 are connected. The upper end of the upper connecting bolt 31 is used to connect with the main vibrating object, and the lower end of the lower connecting bolt 32 is used to connect with the cylindrical iron core 41 on which the excitation coil 46 is wound. Connected, the cylindrical iron core 41 is supported in the magnetic conductive sleeve 44 through the shear magnetorheological elastic body 45 arranged on the outer circumference of the cylindrical iron core. The top of the cylinder 44 and the fix...
