Liaoning Shenyang manufacturing module installation acoustic quality inspection tooling system leading domestically

[ China Instrument Network Instrument R&D ] Recently, Liaoning Shenyang Tianyan Zhiyun Information Technology Co., Ltd. independently developed and tested the tooling system with independent intellectual property rights and replaced foreign imported products, which will be delivered to China Shipbuilding Industry Corporation. This means that another smart manufacturing product representing the domestic advanced level appears in the “Made in Shenyang” list.

Shenyang Tianyan Zhiyun Information Technology Co., Ltd. (formerly Shenyang Hongji Electric Co., Ltd., hereinafter referred to as “Tianyan Zhiyun”) was founded in 2007. It is a collection of big data processing, cloud computing, Internet of Things research and development, and intelligent terminal products manufacturing. An integrated high-tech enterprise. It has built a technology international advanced, domestic leading "emergency rescue of hazardous chemicals", "full-life data collection and analysis", "major equipment logistics management and control" simulation laboratory and test platform. The company has passed ISO9001 international quality system certification, GJB9001C weapons and equipment quality management system certification, and weapons and equipment research and production units three levels of confidentiality certification.

Vibration and noise are everywhere. The measurement of vibration and noise covers all fields of scientific research, production and life. By measuring the sound pressure, sound intensity, frequency and Other parameters of noise, as well as the analysis and calculation of spectrum and sound power, the noise is completed. Evaluation tests provide better control over industrial processes.

The inspection tooling system is called the module installation acoustic quality inspection tooling system, which is mainly composed of three parts: data acquisition front-end hardware, acoustic quality analysis software and excitation system framework. The system is based on acoustic quality detection analysis and research technology to realize the monitoring and analysis function of low-noise construction quality of components and provide technical support for the treatment of vibro-acoustic problems. The excitation system mainly completes the precise adjustment and support of the vibration machine installation. Providing a vibration exciter that meets the requirements; the data acquisition system completes the acquisition of vibration and acoustic signals; the data analysis software system performs data analysis, processing, and automatic reporting.

The test results of the test tooling system are compared with the third-party test institutions with national-level test qualifications. The deviation of the measurement results of all test points is not more than 3 decibels, and the accuracy rate is higher than 90%.
