The invention provides a three-dimensional vibration stress relief multitask acquisition and control system which comprises at least one workpiece, at least one vibration exciter, a sensor matched with each workpiece, a mainframe device and a vibration exciter drive unit, wherein, the sensor acquires a three-dimensional signal of each workpiece; the mainframe device classifies and selects distribution of the inherent frequency and the resonant frequency of each workpiece according to the maximum energy absorption principle and the multi-vibration mode principle and drives the vibration exciter drive unit; and the vibration exciter drive unit drives the vibration exciter to vibrate according to the frequency selected by a mainframe so as to eliminate the stress of each workpiece through vibration. The system and a method thereof provided by the invention have the following advantages of achieving more simplified and more convenient acquisition, ensuring that the distribution of the resonant frequency with different vibration patterns of each workpiece is wider and data is more perfect without omission in Fourier spectrum analysis, ensuring that the obtained result is more accurate while classifying and selecting the resonant frequency for Fourier spectrum analysis, and ensuring that vibration ageing treatment effect is better.
Description
technical field [0001] The present invention relates to a collection and control system and method for eliminating stress by vibration, especially a system including several control units. Each control unit adopts three-dimensional data acquisition, which can independently collect data. Task acquisition and control system and method thereof. Background technique [0002] Vibration Stress Relief Technology (VSR) uses a strictly controlled vibration energy to process metal workpieces to solve the problem of dimensional changes and load-resistant changes caused by internal residual stresses during and after machining. VSR has an important effect on eliminating, reducing or homogenizing the residual stress in the metal workpiece, improving the workpiece's ability to resist dynamic and static loads, deformation resistance, and stabilizing dimensional accuracy. [0003] At present, in the existing vibration stress relief system, one control device can only connect one set of sens...
