The invention discloses a residual unbalance detection device and method of a single-side rotation body. The device comprises a support seat, a frame-shaped installation rack, a driving source, an acceleration sensor, a rotational speed sensor, a scale, a data acquisition front end and a computer, wherein the installation rack is arranged on the support seat, the driving source is used for providing power, the data acquisition front end is used for receiving data of the acceleration sensor and the rotational speed sensor, the computer is used for processing the data, the installation rack comprises an upper installation rod, a lower installation rod and a plurality of elastic connection pieces, the upper installation rod and the lower installation rod are arranged in parallel, and one endof each elastic connection piece is fixedly arranged on the upper installation rod and the lower installation rod. The detection method comprises the steps of A, arranging the device; B, starting thedevice to acquire the data; and C, processing the data by the computer. Relatively reliable residual unbalance of the single-side rotation body can be obtained without special dynamic balance equipment, the device is simple, and existing resource such as the acceleration sensor can be flexibly used for obtaining a detection result by matching a calculation formula. By the detection method, auxiliary calibration can be performed on the test result of the dynamic balance detection equipment.
Description
Technical field [0001] The invention relates to a device and method for detecting the residual unbalance of a single-sided rotating body. Background technique [0002] The single-sided rotating body is a commonly used part in machinery, and it is one of the sources of unsteady mechanical operation. The difference in the residual unbalance will directly affect the running stability, reliability, durability and vibration characteristics of the single-sided rotating body. Under normal circumstances, single-sided rotating body manufacturers or testing institutions use professional dynamic balancing machines and specific single-sided rotating body fixtures to test the remaining dynamic imbalance of the single-sided rotating body. When limited by conditions and without professional dynamic balance testing equipment, objective values cannot be given for the residual dynamic unbalance of a single-sided rotating body. However, when the residual dynamic unbalance value of the single-sid...
