With the rapid development of high-speed railways, urban rail transit, and elevated expressways in China, sound barriers, as key facilities for controlling traffic noise and improving the living environment of residents along the line, have increasingly attracted attention to their structural safety and durability. In order to meet the market's demand for high-end testing equipment, Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") has officially released a new generation of fully automatic sound barrier fatigue testing machine with years of technological accumulation. The emergence of this device marks a solid step forward for Xinguang in the field of material mechanics testing, providing strong technical support for quality control and scientific research innovation of sound barrier products.
The long-term exposure of sound barriers to strong winds, fluctuating wind pressure during train passage, and complex climatic environments directly affects the fatigue resistance of their connectors, columns, and screens, which directly affects driving safety and the durability of noise reduction effects.
The sound barrier fatigue testing machine launched by Xinguang this time is designed strictly in accordance with national and industry standards such as TB/T3122-2019 and HJ/T90-2004. This device adopts advanced electro-hydraulic servo control technology and has the following outstanding advantages:
1. High precision dynamic loading: It can accurately simulate the alternating load that the sound barrier is subjected to over decades of use, monitor changes in load and displacement in real time, and accurately draw fatigue curves.
2. Large tonnage and long stroke: In response to the large size and heavy weight of the sound barrier screen and column, a sturdy top structure host has been designed to meet the testing requirements of ultra large components.
3. Fully automatic intelligent control: equipped with a measurement and control system independently developed by Xinguang, it can achieve waveform output such as sine wave, triangular wave, square wave, etc., automatically determine sample fracture and test termination, and truly achieve unmanned long-term continuous testing.
4. Multiple safety protection: Equipped with beam limit, overload protection, oil temperature alarm and other multiple safety mechanisms to ensure the stability and safety of the equipment under long-term high load operation.
Although the sound screen barrier is a 'wall', it is also an important barrier to ensure the quiet life of the people and safeguard the safety of train operation, "said the person in charge of Xinguang Technology." We hope to provide high-precision fatigue testing machines to help production enterprises optimize product structure, help testing institutions strictly control quality, and jointly promote the high-quality development of China's traffic noise control projects
At present, the equipment has been put into use by multiple third-party testing institutions and leading sound barrier production enterprises in China, with stable operation and high praise from customers. In the future, Xinguang will continue to uphold the craftsmanship spirit of "striving for excellence", constantly explore in the field of material testing, and create greater value for customers.
