Linear vibration: If all the basic components of a vibratory system – the spring the mass and the damper behave linearly, the resulting vibration is known as linear vibration. Principle of superposition is valid in this case. Nonlinear Vibration : If one or more basic components of a vibratory system are not linear then the system is nonlinear.

Linear vibration motor(LRA) provides faster response time and longer usage life when compared with ERMs. As such, linear vibration motor(LRA) is more commonly used in handsets, wearable vibration, mobile phone vibration. Moreover, linear vibration motors(LRA) are capable of vibrating at a more steady frequency with less power drain, delivering better quality for the handset haptics experience. …

In the case of the spring–mass–damper model, the system is linear if the spring force is proportional to the displacement and the damping is proportional to the velocity over the range of motion of interest. Hence, the solution to the problem with a square wave is summing the predicted vibration from each one of the harmonic forces found in the frequency spectrum of the square wave.

Linear Vibration vs Pivotal Oscillation. Linear vibration and pivotal oscillation are the two major types of motion patterns of all vibration plates in the market. Manufacturers may use different words to refer to these two motion patterns for their vibration machines. Pivotal oscillation is created using, in mechanical term, a planar four-bar linkage device. It is a seesaw motion centered on ...

Liu et al. developed a linear model of a vibrating screen supported in four different positions with different stiffness under a vertical force. This model did not consider the possibility of lateral motion of vibrating screen deck. They simulate supporting positions with loose of stiffness but because of model formulation they obtain a change in amplitude of the vertical displacement of the center of mass but movement …

Three different drive motors give linear vibration, horizontal vibration, and oscillation. Users can choose between three drive modes and see what works best for their body.
