摘要： A multi-cylinder reciprocating compressor includes a cylinder block provided with a plurality of pistons each for performing a working fluid suction stroke and a working fluid compression/discharge stroke, and a cylinder head arranged adjacent to the cylinder block. The cylinder head defines therein a discharge chamber and an annular suction chamber surrounding the discharge chamber and has a plurality of cross walls arranged at intervals in a circumferential direction thereof. The cross walls reduce the cross-sectional flow area of the suction chamber.

摘要： A multi-cylinder compressor includes a valve plate having a plurality of cylinder suction ports formed therethrough, and a plurality of cylinder bores centered on an arc having a radius (R). The cylinder bores are substantially equally spaced from each other, and have a diameter (D). The compressor also includes a suction chamber having a substantially annular shape and adapted to be in fluid communication with each of the cylinder bores via the suction ports. Moreover, a center of a first of the suction ports is radially offset in a predetermined direction from a center of a predetermined suction port by a first angle, in which the predetermined suction port has a diameter (d), and the first angle equals {[(360°/N)·([N−1]−n)]+X°}. In this formula, N is a number of the suction ports formed through the valve plate, n is a number of the suction ports positioned between the first suction port and the predetermined suction port in a direction opposite to the predetermined direction, and X° is a predetermined angle which is less than or equal to {(sin−1[(D−d)/2·R])·57.3°/Radian} and greater than or equal to −{(sin−1[(D−d)/2·R]·57.3°/Radian}, and which is not equal to 0°.

摘要： Methods and apparatus for control and monitoring of wind turbines. Various embodiments pertain to the operational analysis of vibratory modes of the blades of the wind turbine. This real time analysis of blade modal response can be used as feedback in a control system to change the yaw angle of the hub and nacelle to capture higher power from the wind stream, change the pitch on one or more blades to reduce uneven blade loading, to identify damage to a blade, and further to identify the accumulation of ice on a blade.

摘要： Structural health monitoring systems can be limited to a minimum number of sensors due to cost, complexity, and weight restrictions. Some embodiments described herein pertain to a load and damage identification techniques that utilize one sensor. Several passive force estimation techniques are presented. Some techniques use either the shape or the amplitude of the magnitude of the applied force in the frequency domain. Several techniques iteratively reduce an underdetermined set of equations of motion into many overdetermined systems of equations to solve for the force estimates. The techniques are shown to locate and quantify impulsive impacts with over 97% accuracy and non-impulsive impacts with at least 87% accuracy. Impacts not acting at a specific input degree of freedom are also accurately located depending on the distance away from the modeled input degrees of freedom, and damaging impact forces are quantified by making assumptions about the impulsive nature of the applied force.

摘要： The present invention includes a method and system using dynamic pressure measurements for determining a presence, location, and size of a leak in a chamber of a body. The method includes sealing a plurality of ports of the chamber, pressurizing the chamber with a fluid, measuring a dynamic pressure at each of the plurality of ports, and analyzing the dynamic pressure measured at each of the plurality of ports to determine a presence, location, and/or size of the leak. The location of the leak can be determined by analyzing magnitude and/or phase values from a generated frequency response function matrix, interpolating between two of the plurality of ports, triangulating between three of the plurality of ports, and/or analyzing a rate and profile at which the pressure decays at each of the plurality of ports to determine the location of the leak.
