ABSTRACT
During the modern industrial production, the residual stress caused by the
production has direct bad effection on the characteristic of the work, which seriously
harm the quality and structure safety of the work. Therefore, it is important to relieve
and decrease the residual stress for the manufacturing security . As a kind of new stress
relief technology, vibration stress relieve technology has been widely used in the fields
which are relative to the casting、forging、mould and welding because of its advantages
such as low cost, flexibility, environment-friendly, energy-conservation and
mechanical property improvement. Intensively study the vibration stress relief
technology and design a vibration stress relief device which is high efficiency ,
energy-conservation and high intelligence have far-reaching and momentous
significance for the industry manufacturing improvement..
The article introduce the design of the vibration stress relief device which is
controlled by the computer based on the analysis of the vibration stress relief theory and
technology .The device can work at different modes, such as automatic /manual sweep,
automatic /manual frequency fix and so on. The general design plan is based on the
national standard JB/T 5925.1-2005(mechanical vibration stress relief device).Then,
the system schematic diagram is designed. Finally, detail design of the hardware and
software parts are introduced respectively.
The hardware part introduce the design of the circuit of the sensor、motor and the
interface circuit between the system hardware .The hardware circuit mainly include the
vibration generator motor driving circuit 、accelerator signal processing circuit and
peripheral circuit of the microcontroller.
The software part introduce the design of the whole vibration stress relief flow、
computer and microcontroller software base on the general design plan and hardware
circuit. Use labview and C language to design the computer and microcontroller
software to achieve the serial communication between the computer and
microcontroller,data collection,processing,displaying,saving ,printing and vibration
frequency controlling so that the device can relieve the residual stress by using
computer to control the microcontroller fulfill the vibration stress relief technology.
The hardware design of this device is simple and its’ operation interface is concise
so that it is convenient for user to operate the device. In addition, this device provides
multi-modes for user to choose. User can choose the proper mode to fulfill the vibration
