Dynamic machines defined

The unique natural frequencies of dynamic machine components are determined by the mass, freedom of movement, support stiffness, and other factors. These factors define the response characteristics of the rotor assembly (i.e., rotor dynamics) at various operating conditions. [Pg.734]

Another commonly quoted value is the ratio of the maximum trough acceleration to g (as opposed to the previously defined vertical acceleration ratio), K, the dynamic machine... [Pg.230]

Capacity Definitions In any analysis, the capacity per unit time of dynamic equipment (such as conveyors and bagging machines), as well as the rates at which they ac tuaUy perform, must be defined more precisely and realistically than by a mere statement of kilograms or pounds per hour. Some useful definitions employed by the equipment industi y are the following ... [Pg.1911]

The software used to manage the data incorporates what are referred to as analysis parameter sets (APSs). APSs define and specify machine dynamics, components, and failure modes to be monitored. [Pg.715]

The amplitude of each point of imbalance must be known to resolve dynamic balance problems. Most dynamic balancing machines or in situ balancing instruments are able to isolate and define the specific amount of imbalance at each point on the rotor. [Pg.938]

Today, five main aspects must be taken into account machines, chemicals, environment, farmer, and agricultural products. These five aspects must be considered as a unique system or a dynamic system with close interaction (Fig. 3). Future standards should take these into consideration in the development of better quality in agriculture and environment. Standards should clearly define test procedures to ensure uniformity within all institutions carrying out tests. [Pg.259]

For simplicity, all oil test parameters are defined by the same attributes and each attribute s status is established by appropriate statistically based limits. It is important to remember that parameter level is a scalar of how much damage has occurred, such as contaminant concentration. Parameter trend is a scalar of how fast the damage is occurring and thus a measure of the remaining time to failure. Reliable interpretation of the machine/fluid condition requires an analysis of both parameter level and trend amongst other relevant data, such as statistical rank, that are an indication of individual machine dynamic equilibrium with respect to the fleet mean readings. [Pg.489]

It is assumed that especially in well-defined situations with a low degree of structural and dynamic complexity, centralized planning methods are able to achieve a high degree of logistic performance. However, increasing complexity (e.g., disturbances caused by machine break downs) reduces the logistic performance. In this situation, an increase of the level of autonomy fosters the robustness of the production... [Pg.69]

The main demands of broaching machines are high accuracy, good dynamic behavior, low noise emission, reliable operation, and simple automation (Hoffmann 1976). The elementary construction and exactly defined load requirements make broaching machines to be highly reliable machine tools. It can be differed between the following types of construction ... [Pg.113]

One significant development in the last couple of decades has been increasing use of superhards (PCD, PcBN) in machining. Even though cBN is a ceramic material, it will be discussed in the superhard section. In some applications cemented carbide, which used to be benchmark of performance, is now replaced by superhards to define productivity. This dynamics will play an important role in determining the role of ceramics in the future. [Pg.139]

Experimental Measurement The experimental examination of the TCP s compliance is achieved by exciting the machine structure at this point with a defined force F,(cd) (pulsed or continuously) and by recording its response signal Xi(o ). This procedure occurs analogously for all three directions in space 1, 2, and 3. From Eq. 2, the dynamic compliance ay(cu) can be determined. [Pg.170]

As we mentioned earlier, there is alwt some loss associated with a dynamic s em. In engineering, when we wish to show how well a machine or a system is (uncdoning, we express its efficiency. In general, the overall efficiency of a system is defined as ... [Pg.355]

Common approach to generate motion is to define series of pose and connect them with dynamically stable trajectory. This approach cannot be applied to gel robots. We cannot predefine series of pose because we cannot control their poses directly. Motion control problem of deformable machine made of actively deformable materials are classified into three, which are summarized below. [Pg.166]

In addition to the injection moulding machine, a nitrogen supply, appropriate high-pressure compressor and pressure-control module are required for deploying GIM technology (see Fig. 2.27). The pressure-control module is equipped with a precise, highly dynamic pressure valve that allows defined pressure time profiles to be created. [Pg.78]
