The sweeping-frequency measurement results show that the work frequency, bandwidth, and output-voltage of VEH depend on tuning of GBSS and excitation levels, indicating that the multiple nonlinear effects, such as Duffing-spring effect, impact effect, preload effect, and air elastic effect, have significant influence on the dynamic behaviors of VEH.

Accurate modal analysis is the basis to evaluate the dynamic performance of inflated membrane structures, however, it is still a challenge to analyze and testify due to strong nonlinearity of geometry deformation, initial stress and the air-elastic effects.
The physico-mechanical properties at fresh and hard state were investigated, mainly the density, absorption, air content, elastic modulus and strengths.

An experiment was conducted, for comparison, on a damped cylindrical shell suspended in air by lightweight elastic shock cords and driven at the mid-section by an electromechanical vibration shaker.
After 48 h of air drying, the elastic modulus was approximately 35%, 10 %, 15, and 25% of the mandmum value for Del Rio Clay, Eagle Ford Shale, Taylor Marl, and Navarro Shale, respectively (most of the reduction took place within the first 4 h of drying).
Contamination by PCBs was determined by chemical analysis of indoor air and of elastic sealant materials.
Has he discussed the use of any pressure devices (for example, inflatable air sleeves, or elastic compression stockings)?
Several devices and manmade structures interact dynamically with fluids such as water and air, behaving essentially as flexible elastic systems with large deformations and undergoing complex dynamics.
