Site high-speed dynamic balance method for large steam turbine generator unit shafting

The invention discloses a site high-speed dynamic balance method for a large steam turbine generator unit shafting. The site high-speed dynamic balance method is characterized by comprising the following steps of: 1) preparing to start the large steam turbine generator unit shafting; 2) starting the large steam turbine generator unit shafting, measuring an acceleration characteristic, and recording the change of the vibration of each bearing along with the rotating speed; 3) determining several types of unbalance of the shafting according to the acceleration characteristic, analyzing the unbalance, and determining a weight-increasing scheme; 4) analyzing the vibration after increasing the weight, namely measuring the vibration after increasing the weight for the first time; and 5) after increasing the weight, making corresponding fine adjustment by combining a fastened weight. According to the method, the dynamic balance weight can be added in trial and adjusted on a plurality of balance planes at a plurality of rotating speeds. By the method, mutual influence of the vibration among rotors is pre-quantified during weight adding; the working rotating speed and the critical rotating speed can be balanced at the same time, so that an effect of reducing the number of the balance starting time is outstanding; and the dynamic balance method for the steam turbine generator unit shafting is effective.

Neural network device for evolving appropriate connections

A system and method for evolving appropriate connections in feedforward topological networks. FIG. 1 illustrates an exemplary flow diagram of a method for evolving appropriate connections in a neural network device according to an aspect of the present invention. Initially, weight changes induced by each particular training sample or pattern are calculated using, for example, a conventional network training rule such as Hebb or backpropagation (step 101). Next, a ratio of the weight changes for existing connections to incipient connections ("K" ratio) is calculated (step 103). If this K ratio exceeds a specified threshold, weight changes are implemented (step 105), in which existing weights are increased by (1-E)x(total weight change of existing connections), where E is a network-wide parameter. The remaining amount (E)x(total weight change of existing connections) is added to form neighboring connections (step 107). It is to be noted that if neighboring connections are not yet in existence (i.e, they are incipient connections), they can be created by this mutation rule; however, whether such new connections are created depends on the size of the weight increase computed in step 101, together with the magnitude of E. After cycling through a training set, connections that are weak (e.g., weaker than a specified threshold) are deleted (step 109). Following step 109, the system returns to step 101. Advantageously, a system and method according to the present invention allows a combination of the advantages of fully connected networks and of sparse networks and reduces the number of calculations that must be done, since only the calculations corresponding to the existing connections and their neighbors need be determined.

Lamb fattening complete pellet feed

The invention provides lamb fattening complete pellet feed, which belongs to the field of feed processing in animal husbandry and applies to the intensive complete-barn-feeding production of mutton sheep. According to the nutritional need of lambs in different fattening periods, three types of complete pellet feed are prepared and processed through three formulations in order to satisfy the balanced nutrition supply for weight increase and other aspects except water drinking in a 10 to 15 kg stage, a 15 to 20 kg stage and a 20 to 25 kg stage in a fattening period respectively, so that the factory production of fattening sheep without depending on the conditions of forage grass resources is realized. Due to abundant raw material sources, simple processing technique and low production cost, the pellet feed is beneficial to large-scale commercial production. After application, the pellet feed can ensures that the production of fattening sheep is not restricted to the conditions of natural feed and forage grass resources, and production scale can be adjusted in time according to market demand. Meanwhile, as only one type of pellet geed is used in one fattening stage, more simplified and scientific production process, reliable fattening effect, high production efficiency and low comprehensive cost are ensured.

Multi-rotor joint vibration mode balancing method for single support shafting steam turbine generator unit

The invention discloses a multi-motor joint vibration mode balancing method for a single support shafting steam turbine generator unit. At present, during on-site dynamic balancing of a single support shafting supercritical steam turbine generator unit, vibration information of two ends of rotors is not provided and shaft vibrations influence each other by coupling, so that a certain difficulty is brought into the on-site dynamic balancing of a shafting. According to the multi-rotor joint vibration mode balancing method, unbalanced types of the shafting are judged and calculated by calculating vibration vectors and vibration mode harmonic components and combining characteristics of a single supporting shafting structure according to shaft vibration magnitude values and shaft vibration phases of each rotor of the shafting at a critical rotating speed and a working rotating speed, and then a joint vibration mode of multiple rotors is identified; and a weight-increasing scheme of each plane is directly obtained according to a lag angle, mass-basis response coefficients and a first-time weight-increasing interval, and a group of increased weights are added to a related plane once. By the multi-motor joint vibration mode balancing method, the balancing efficiency and the accuracy of the single support shafting rotors are significantly increased.
