The vibration suppression rate consistently exceeding 85% was exhilarating for the entire team. However, this was still only a result on the test bench. The real test would be to install it on real, new textile machinery and subject it to complex workloads and long-term operation.

The opportunity soon arrived. The project team decided to install their optimized online dynamic balancing device on a prototype machine that was about to undergo final debugging, and conduct a joint trial run.

On the day of installation, many people came to the laboratory and workshop. Team Leader Chen was personally present, and several experienced workers, including Engineer Li, who had previously been skeptical, stood by with their arms crossed, their eyes filled with a mixture of scrutiny and curiosity. The atmosphere was somewhat tense.

Liu Li, Zhou Wei, and Sun Mei worked together, carefully installing the device into the designated position on the prototype's high-speed spindle. They connected the wires, checked, and finally confirmed everything. Each person moved with exceptional gentleness, as if afraid of disturbing something.

"Ready to start!" the commissioning manager issued the command.

All eyes were focused on the massive textile machine. The motor started, the transmission system began to operate, and the spindle speed steadily increased.

Liu Li kept a close eye on the operating data and vibration spectrum transmitted back by the device on the monitoring screen. Zhou Wei stood guard by the control box, ready to deal with any emergencies. Sun Mei recorded the various parameters.

As the rotational speed approached the rated operating point, everyone's hearts were in their throats. This was the range where vibration was most likely to get out of control.

On the monitoring screen, the curve representing the vibration amplitude climbed steadily, but after reaching a certain critical point, the growth trend slowed down significantly and was then steadily suppressed to a lower level! The device had started working, silently driving the mass block to make micron-level compensation adjustments based on the vibration detected in real time.

The machine operates smoothly and evenly, without the unsettling, subtle buzzing noise of the past. The main shaft rotates at high speed, driving the complex spinning mechanism with fluid movements and no sense of sluggishness.

"The vibration amplitude... is stable within the permissible range!" Sun Mei reported the data, her voice filled with an incredulous excitement, "It's reduced by 88 percent compared to before the device was installed!"

"All institutions are operating normally!"

"Yarn quality inspection shows a significant decrease in breakage rate!"

"The noise level has been significantly reduced!"

A series of good news came from various monitoring points.

Li, who had been staring intently at the machine, gradually turned his doubt into surprise. He couldn't help but take a few steps closer, listen carefully to the operating sounds, and look at the monitoring data. Finally, he slowly nodded and whispered to the person next to him, "Hey... this thing is really something."

Team Leader Chen's previously tense face finally broke into a clear smile. He walked up to Liu Li and the other two, his gaze sweeping over their cheeks flushed with tension and excitement. He nodded and said succinctly, "Well done."

The joint trial run, which lasted for several hours, came to a successful conclusion. The moment the machine came to a smooth stop, enthusiastic applause erupted in the laboratory and workshop! This applause was for the successfully operating prototype, but even more so for Liu Li and her team, and for the online dynamic balancing device that went from an "out-of-the-box idea" to a "great success"!

The success of the device not only solved the core technical bottleneck of high-speed spindle vibration and ensured the performance indicators of the new textile machinery, but also proved with irrefutable facts the enormous potential and value of this independent innovation technology route.

Liu Li, Zhou Wei, and Sun Mei exchanged smiles. All their fatigue, stress, and past doubts vanished in that moment, replaced by a profound sense of accomplishment and boundless anticipation for the future. They knew this was just the beginning; a wider world of applications awaited their exploration.
