The relevance of this topic stems from a persistent trend toward increasing vibration loads in high performance light industry equipment, caused by the reduction in weight and rigidity while simultaneously increasing operating speeds. The problem is that increased vibration and noise from multi-needle semiautomatic embroidery machines with sewing heads degrades embroidery quality, reduces the equipment's service life, and negatively impacts the health of operating personnel. The goal of this study is to reduce vibration and noise levels by balancing the inertial forces of the moving parts of the needle and thread take-up mechanisms. Research methods include computer-aided analytical modeling of inertial forces, calculation of optimal static counterweight moments, experimental testing on a prototype with varying crank masses, and spectral analysis of vibration velocity and noise levels in octave frequency bands. The results obtained: the optimal static counterweight moment (2.5×10⁻³ kg m) was determined, ensuring the minimum sum of the horizontal and vertical components of vibration velocity in the needle plate area. It was found that balancing the inertial forces does not significantly affect the noise level. Further improvement of the transmission angles in the thread take-up mechanism reduces noise by 2–3 dB. The area of application of these results is the modernization of semi-automatic embroidery and sewing machines into semi-automatic embroidery machines in light industry enterprises.
