The shearing strength of the structural layer mainly depends on the normal stress of the shear plane and the internal friction resistance angle within materials.
The particles and shape of gravel materials need to satisfy certain requirements, which specific requirements should be consistent with the requirements of the table 1.
When loading materials, it is necessary to respectively load the three parts of aggregates in the place of upper, middle and lower so as to avoid segregation
(3) Segregation should be in the charge of specially-assigned person, respectively for adding materials, watering and leveling up or directly digging out for another material

Through analysis, when the system vibrates near the resonance frequency, deformation of spring is greater, E-ACE materials to move up and down reach the larger amplitude, and the more energy it produces.
Dielectric elastomer material can be used as positive, the optimal bionic artificial muscle drive materials and also can be used reverse, as power or sensing.
In the overall effect diagram, E-ACE materials and vehicle vibration device because the whole assembly.
