  2. Production leveling - Wikipedia

    en.wikipedia.org/wiki/Production_leveling

    Uneven production process in simulation inside production simulation game in Ford's Museum. Production leveling, also known as production smoothing or – by its Japanese original term – heijunka (平準化), [1] is a technique for reducing the mura (unevenness) which in turn reduces muda (waste).

  3. Balancing of rotating masses - Wikipedia

    en.wikipedia.org/wiki/Balancing_of_rotating_masses

    The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of rotation

  4. Perry–Robertson formula - Wikipedia

    en.wikipedia.org/wiki/Perry–Robertson_formula

    The Perry–Robertson formula is a mathematical formula which is able to produce a good approximation of buckling loads in long slender columns or struts, and is the basis for the buckling formulation adopted in EN 1993. The formula in question can be expressed in the following form:

  5. Balancing machine - Wikipedia

    en.wikipedia.org/wiki/Balancing_machine

    A balancing machine is a measuring tool used for balancing rotating machine parts such as rotors for electric motors, fans, turbines, disc brakes, disc drives, propellers and pumps. The machine usually consists of two rigid pedestals, with suspension and bearings on top supporting a mounting platform.

  6. Paris' law - Wikipedia

    en.wikipedia.org/wiki/Paris'_law

    Paris' law (also known as the Paris–Erdogan equation) is a crack growth equation that gives the rate of growth of a fatigue crack. The stress intensity factor K {\displaystyle K} characterises the load around a crack tip and the rate of crack growth is experimentally shown to be a function of the range of stress intensity Δ K {\displaystyle ...

  7. Harmonic balance - Wikipedia

    en.wikipedia.org/wiki/Harmonic_balance

    Harmonic balance is a method used to calculate the steady-state response of nonlinear differential equations, [1] and is mostly applied to nonlinear electrical circuits. [2] [3] [4] It is a frequency domain method for calculating the steady state, as opposed to the various time-domain steady-state methods.

  9. Birks' law - Wikipedia

    en.wikipedia.org/wiki/Birks'_Law

    The relation is: = +. where L is the light yield, S is the scintillation efficiency, dE/dx is the specific energy loss of the particle per path length, k is the probability of quenching, [1] and B is a constant of proportionality linking the local density of ionized molecules at a point along the particle's path to the specific energy loss; [1] "Since k and B appear only as a product, they act ...
