The development trend and intelligent upgrade of vibration aging instrument

With the advancement of industry4.0With the arrival of the times, vibration aging instruments are undergoing profound technological changes. Intelligence, automation, and informatization have become the main directions for the development of vibration aging equipment. This article will analyze the development trend of vibration aging instruments and explore the technological innovations brought about by intelligent upgrades.

The intelligent upgrade of the vibration aging instrument is first reflected in the innovation of the control system. The new generation of VSR adopts an intelligent control system based on industrial Internet, which can realize remote monitoring and management of equipment. Through IoT technology, operators can view the real-time operation status, processing parameters, and timeliness of devices from anywhere through their mobile phones or computers. The system also has self diagnostic function, which can automatically identify faults and provide repair suggestions, greatly improving the reliability and maintenance efficiency of the equipment.

In terms of data processing and analysis, modern vibration aging machines are equipped with * data acquisition and analysis systems. The device can collect real-time vibration signals, stress changes, and other data, and establish a mathematical model between the workpiece and process parameters through big data analysis technology. Based on machine learning algorithms, the system can automatically optimize process parameters based on historical data, achieving personalized and precise time processing. This intelligent parameter optimization not only improves processing efficiency, but also reduces reliance on operator experience.

The development of vibration aging instruments is also reflected in functional integration. The new equipment not only performs vibration aging treatment, but also integrates multiple functions such as stress detection, deformation measurement, and quality evaluation. A complete quality control system has been formed through linkage with other testing equipment. For example, automatic stress detection is performed before and after processing to evaluate the timeliness effect in real time, ensuring that each workpiece meets the predetermined quality standards.

In terms of hardware, vibration aging instruments are developing towards miniaturization and lightweighting. The new exciter adopts rare earth permanent magnet materials and precision manufacturing technology, greatly reducing its volume and weight, while significantly improving the excitation force and frequency range. This enables vibration aging technology to be applied in more situations, especially in environments with limited space.

Looking ahead to the future, vibration aging instruments will be more closely integrated into intelligent manufacturing systems through collaboration withMESTheERPIntegrate the management system to achieve full process digital management of the production process. The application of artificial intelligence technology will enable vibration aging machines to have stronger autonomous decision-making capabilities, truly achieving unmanned automated production. These technological innovations will drive the application of vibration aging technology to new heights in the manufacturing industry.

Scientific and rational use of vibration aging machines is something that every on-site user should master

1、 Understanding Vibration Aging (Mechanism of Vibration Aging)

The essence of vibration aging is to apply a dynamic stress to the workpiece through vibration. When the dynamic stress is superimposed with the residual stress of the workpiece itself, reaching or exceeding the micro yield limit of the material, the workpiece will undergo micro or macro local and overall elastic plastic deformation, while reducing and homogenizing the residual stress inside the workpiece, ultimately achieving the goal of preventing workpiece deformation and cracking, stabilizing workpiece size and geometric accuracy.

2、 Common problems during the use of vibration aging machine (customer feedback on poor aging effect)

Due to some users' lack of understanding of the mechanism of vibration aging, they blindly use some simple methodsFully automatic vibration aging equipment is used to age products. This method, which does not target the individuality of the workpiece and only uses one or several process parameters pre-set by the vibration aging equipment manufacturer for aging various workpieces, can lead to the following situations for the aged workpiece:

1. False time effect: If the workpiece does not resonate or has a small amplitude, or if the amplitude is large but the workpiece as a whole undergoes rigid body vibration or oscillation, the "fully automatic vibration time effect equipment" can also print or output various time effect parameters and curves according to the preset program, misleading the operator and process personnel to judge, so that the workpiece does not achieve the time effect at all;

2. Mistime effect: Although the workpiece resonates, the vibration mode that occurs is not consistent with the required vibration mode of the workpiece, and the dynamic stress is not applied to the part of the workpiece that needs to be relieved of stress, which cannot achieve the expected time effect of the workpiece and affects the effectiveness of the time effect;

3. Overdue: Due to not adopting reasonable aging parameters based on the individuality of the workpiece, blindly setting parameters for aging the workpiece may lead to severe consequences such as internal defects (cracks, slag inclusions, pores, shrinkage, etc.) expanding, tearing, and even scrapping due to excessive resonance or amplitude.

3、 Process analysis of vibration aging

　　 From the current situation of the vibration aging process mentioned above, it can be seen that blindly using fully automatic vibration aging process for workpiece aging treatment is pseudoscientific. This not only fails to achieve the aging purpose of the workpiece, but also leads to serious consequences, such as workpiece cracking and even machine damage and human death.

So, what kind of vibration aging process is scientific?

Firstly, it is necessary to analyze the residual stress distribution of the workpiece, the requirements for form and position accuracy, as well as the future working load and possible causes of failure before aging, in order to develop a reasonable vibration aging process, determine the aging route and key aging parts.

1. Analysis of form and position accuracy:

Based on the straightness of the workpiececylinderDifferent excitation forces and vibration modes should be selected for degrees, flatness, coaxiality, symmetry, etc.

2. Resonance frequency analysis:

Select different support methods or use vibration platforms for processing based on the strength, rigidity, and batch size of the workpiece.

3. Vibration mode analysis:

Different frequencies correspond to different vibration modes, and different vibration modes correspond to different dynamic stress fields.

4. Work load:

In response to the future deformation of the workpiece during work, it is important to eliminate residual stresses in the parts of the workpiece with high loads under working conditions, and select the corresponding vibration mode for aging treatment.

5. Failure analysis of working conditions:

Based on potential issues in the future, different excitation forces and durations should be selected for aging treatment. Secondly, vibration aging equipment should be scientifically selected based on the workpiece being aged. We should not choose some simple, so-calledFully automatic vibration aging equipment; After gaining a deeper understanding of the mechanism of vibration aging, it is necessary to compare and select such vibration aging equipment:

㈠ Stable operation, closed-loop speed control, reliable fixed speed, online printing, high cost-effectiveness:

㈡ Strong and weak electrical isolation, strong self-protection function, low failure rate, easy maintenance:

㈢ Easy to operate, capable of human-machine dialogue, and able to set device operating parameters by inputting passwords through the panel, Without the need to change hardware settings:

㈣ Regardless of the operating mode used (manual, semi-automatic, fully automatic, programming), it can achieve multi peak automatic recognition, multi vibration mode timeliness, and local scanning and printing; And it can be tailored to the personality of the workpiece, using super manual (which can directly and quickly complete pre vibration scanning, printing, recognition, timeliness, and post vibration scanning based on the operator's experience and willingness) to complete the vibration timeliness of useful peaks, avoiding the handling of useless peaks; And it can also manually find a large number of process parameters, conduct scientific analysis, identify commonalities of the same parts, quickly and conveniently program and store them on the panel, so as to call for scientific and fully automatic time processing of workpieces at any time in the future.
