Abstract This paper elaborates a nonlinear fluidic low frequency vibration isolator designed with the characteristics of quasi-zero stiffness (QZS). The existing
model of QZS vibration isolator enhances amplitude of vibration and attenuating
vibration frequencies. This concern with displacement plays a vital role in the performance and instability of oblique spring setup reduces the isolator performance
in horizontal non-nominal loads, in this accordance; this paper associates double
acting hydraulic cylinder (fluidic actuators in short) in oblique and helical coil
spring. An approximate expression of unique analytical relationship between
the stiffness of vertical spring and bulk modulus of the fluid is derived for… More >
