Investigation of vibration-insulation of the industrial sewing machine

The approximate mathematical model of sewing machine oscillating system with insertion of vibration-insulated padding was developed. The mathematical model as a system with two freedom levels is offered. The solutions are obtained in the form of the planned points oscillations of the sewing machine head and the industrial table. For the model adequacy control the calculations of amplitude of the planned points oscillations and the experimental measurements of the logarithmic levels of these points were done. As a result in was established that the error of calculation method doesn’t exceed 2 % and the suggested model evaluates the system oscillating level accurately enough.
