  • Study on a PZT actuator based on pre-stressed mechanism
    The ³zero´ spring rate for a Belleville spring assembly at the neutral position of the elastic suspension if approximated will produce a stable disc spring suspension having an infinitely low natural frequency provided this assembly is deflected to a flat stressed condition.
  • Development of an Innovative Pre-stressed PZT Actuator by FEA and Experiment Verification
    The "zero" spring rate for a Belleville spring assembly at the neutral position of the elastic suspension if approximated will produce a stable disc spring suspension having an infinitely low natural frequency provided this assembly is deflected to a flat stressed condition.

    This Model II version utilizes Belleville springs rather than a helical spring and does not deflect the gas flow as much. Natural frequency is higher (515 cps) because of stiffer springs and smaller moving mass, reducing acceleration-loading effects.
  • Pressure Reactive Piston Technology Investigation and Development for Spark Ignition Engines
    The spring constant and preload are determined experimentally by using an Instron Machine. where K is spring constant, Fpre is preload, and c is the damping coefficient of the Belleville spring . It is important to note that the calculated natural frequency of the piston crown (∼41,000 rpm), is much higher than the normal operating engine speed. y2 is the distance between the crankshaft axis and lower piston and its second derivative is...

  • Developments in Gas Conductor-Cooled Generators
    The stators of 1800-r/min generators have not been subject to abnormal core amplitude presumably because of their relatively high natural frequencies in the 4-lobe mode excited As in the 3600-r/min stators, Belleville springs and individual self-equalizing finger plates are employed.

    1.1) with (1.2) where x(t) is the sinusoidal input (displacement) of the system (with amplitude equal to X), ω is its natural frequency , and α(t) is the ratio X/F. As shown in Fig. 5, such an element has been designed and manufactured and is composed of two precision belleville springs coupled in parallel.

    This preload can be varied by stacking in different sizes and arrangements Belleville springs as shown in Figure 5-3. It is shown by Lindley that for Natural rubber the addition of fillers have a considerable stiffening effect on the low frequency complex modulus of rubber and much lower effect on the high frequency complex modulus.
  • Reactor operating experiences, 1972--1974
    These pulsations occurred from a combi­ nation of flow turbulence, inlet coolant impact on the barrel and excita­ tion of the known 0.5 hz. natural frequency of the system. This design does not depend on interference fit for achieving holddown load, but rather on a series of Belleville spring units contained within pockets in the flange of the up­ per guide structure and compressed against the reactor vessel closure head.
