摘要： A method is described for calibrating a balancing machine, in which a rotor (1) to be corrected is rotatably mounted in bearings (2) and a correction run k is performed, wherein at least one measuring sensor (3) determines an initial vibration of the rotor (1) prior to an imbalance correction and transmits this vibration to an evaluation device (4), which stores the measured value as vibration vector {right arrow over (s)}0. After an imbalance on the rotor (1) is corrected, a residual vibration of the rotor (1) is measured by measuring sensor (3), transmitted to the evaluation unit (4) and stored as vibration vector {right arrow over (s)}1. The difference δ{right arrow over (s)}={right arrow over (s)}1−{right arrow over (s)}0 formed from the measurement data and the corrected imbalance is stored for compensation run k as δ{right arrow over (s)}k and {right arrow over (u)}k by the evaluation unit (4). To undertake a calibration of the machine, one can either determine a process calibration matrix K by solving the equation system S=UKT using the collected measurement data or one can select an already available process calibration matrix using the initial vibration {right arrow over (s)}0 and/or imbalance vector {right arrow over (u)} and store it as a calibration matrix in the evaluation unit (4) and use it to calculate an unknown imbalance vector of a rotor (1).

摘要： In a component mounting system having an inspection device performing a mounting inspection after component mounting, a correction value for correcting a mounting program is calculated based on board inspection information including fed-back component position deviation information, a component is mounted on a board in accordance with the mounting program corrected based on the calculated correction value, and a “present value” based on most recent board inspection information and a “pre-correction evaluation value” are displayed together on an evaluation value display screen as evaluation values representing accuracy at a time of the mounting based on the board inspection information during this component mounting work, the “pre-correction evaluation value” being calculated based on a temporary position deviation amount pertaining to a case where it is assumed that no correction based on the calculated correction value has been performed.

摘要： Gas turbines are used for power generation with units in a range of sizes. They serve as power plants for both military and commercial aircraft. Demand is for faster, lighter engines, utilizing more advanced manufacturing processes. One of the means of meeting this goal is through use of longer, thinner, more flexible shafts which operate supercritically. Supercritical operation was once viewed as impractical, however, a number of today's production gas turbines operate in this mode. The shaft manufacturing process is optimal if the shaft balance procedure can be conducted at low speeds, rather than requiring a more expensive and complicated high speed balance process. One embodiment of the present invention includes a systematic process for a low speed balance procedure which, would permits a high speed shaft system to transition through additional critical speeds and operate safely above them. Still other embodiments of the present invention pertain to analytical modeling and analysis of representative shaft systems to determine the optimum locations of the balance planes and an approach for predicting shaft responses.
摘要翻译： 燃气轮机用于发电，具有一定尺寸的单位。 它们用作军用和商用飞机的发电厂。 需求是更快，更轻的发动机，利用更先进的制造工艺。 实现这一目标的手段之一就是通过使用更加长，更薄，更灵活的轴进行超临界操作。 超临界操作曾经被认为是不切实际的，但是今天的一些生产燃气轮机在这种模式下运行。 如果轴平衡过程可以以低速进行，而不是要求更昂贵和复杂的高速平衡过程，轴制造过程是最佳的。 本发明的一个实施例包括用于低速平衡过程的系统过程，其将允许高速轴系统通过附加的临界速度转换并且安全地在其上操作。 本发明的其它实施例涉及代表轴系统的分析建模和分析，以确定平衡面的最佳位置以及用于预测轴响应的方法。
