The
author proposes a new method and device for its realization [1,2].
The article qives The results of studies of technological capability of
automated machines (ASHM330), where the first needle deflection is involved in guiding the workpiece during sewing.
The purpose of dynamic analysis is to
develop a mathematical model of efficiency ASHM330 providing quality lines.

The
deformation of the edge details with ASHM330 not exceed permissible value , that is, provided
conditions are equidistant lines with respect to the circuit details
, (1)
where - the deformation of
the edge details of the fence.
Note
that this is the strain at every step of the stitch in the process of
orientation with ASHM330 makes the part, "recoil" from the stop after
leaving the needle on the material [3]. Since this process is repeated at every
turn, it seems that part varies automatically.
So, for
the determination of the light and dry friction conditions (1), the principle
of D ¢ Alambera, we write the equations of equilibrium of forces acting:
, (2)
where F - principal vector of the mass center
of friction, taking into account dry friction; Puí - inertia moving
parts, Puí=m∂ a∂,
, where m∂ - weight,
a∂ - acceleration
details, NÀ - normal pressure parts for
emphasis; = Rcosφ;
- orienting force.
,
(3)
- reaction to the needle deflecting material during its orientation;
- the pressure of the
transporting roller to the material;
- drag coefficient between the rollers and the material;
- the distance from the needle and roller until it stops;
- location of stops.
A Coulomb drag force between the material and
the surface of a platform machine is determined by the formula
, (4)
here, , Q=Nc - the pressure of an additional rail on the
workpiece;
ê=f - coefficient of friction parts of the needle
plate;
Ψ - angle of
rotation of the orienting parts in the sewing process;
r1, r2 - radius vector joining the origin of the system and the element
ds;
υ -
velocity components;
ω -
angular velocity of the details in its orientation;
g - acceleration of gravity is the details;
- radius of the stop.
ð - density distribution function details.
But inertia is defined as, where - the center of mass acceleration
details.

Conclusions: Studying (3 and

parameters of the new device
as ω , ψ, , , , which were used to develop
ASHM330. Here are the results of studies of the dependence R() and () using the program Maple 6, the graphs show (Fig. 2), which
