Abstract

The invention provides a vibration aging system based on variable-frequency speed regulation and a numerical simulation technology. The vibration aging system comprises a host computer system, a D / A converter, a frequency converter, a speed-adjustable motor, a strain sensor, a dynamic strain gauge, a data acquisition card and a supporting device, wherein a vibration exciter is fixed on the surfaceof a component which is supported by the supporting device with elasticity; an excitation signal outputted by the host computer system is input to the frequency converter via the D / A converter, so the speed-adjustable motor is driven to generate vibration; the strain sensor is attached to the component, and the outgoing line of the strain sensor is connected with the input end of the dynamic strain gauge; the output end of the dynamic strain gauge is connected with the input end of the data acquisition card; and the output end of the data acquisition card is connected with the host computer system. The vibration aging system of the invention has the advantage of capability of improving the efficiency of vibration aging treatment and acquiring ideal vibration aging to eliminate residual stress.

Description

technical field [0001] The invention relates to the technical field of vibration aging, in particular to a vibration aging system based on frequency control and numerical simulation technology. technical background [0002] How to eliminate the residual stress in the process of component manufacturing is an important research topic in the field of mechanical manufacturing industry. The traditional residual stress relief method is mainly thermal aging technology. However, the disadvantages of thermal aging technology in application mainly include high energy consumption, long aging treatment time, expensive heat treatment equipment, difficult on-site operation, and easy to cause environmental pollution. Vibration aging technology has the characteristics of good treatment effect, short treatment time, less environmental pollution, low energy consumption, and easy on-site operation. technical possibilities. Therefore, research on vibration aging technology has important theor...
