## Abstract

In article it is showed the definition technological parameters of one chamber two saw cylinder gin. For maintenance of efficiency of ginning and productivity increase it is necessary to choose correctly diameter of the working chamber, an arrangement corner saw cylinders under the relation of a horizontal axis. These factors are major factors influencing productivity and quality of a fiber at practical and theoretical researches of one chamber two saw cylinder gin.

**Keywords:**Regression Model; Optimization of Parameter; Angular Position; Saw Cylinder

## Introduction

Using the results of the theoretical study including the literary survey of gins and also taking into account the primary one-factor experiment, the choice of the output parameters affecting the incoming factors was chosen as follows.

Feed rolls 1 feeding the pin drum 2, a bracket and a clamping bar 3, a brush drum 4, a shaft of the brush drum 5, a saw cylinder 6, an upper grate 7, a gin working chamber 8, a lower grate 9, a cement cylinder 10, a screw 11, knife-like mesh surface 12 (Table 1) and (Figure 1).

I. Calculation of the productivity of the fiber. Define the coefficients of regression:

Write the equation according to a certain regression coefficient:

Let.com determine the regression coefficient by acceptability.

To do this, we define the variance of the output parameters

And based on the determination of the regression coefficient, we calculate the variance:

When determining the regression coefficient, we determine the standard deviation:

After this, using the following equation, we determine the indications by the Student's criteria:

It is known that if the calculated criterion data are lower than those given in the data table, then the coefficient is not important and we derive the data from equation It was found that for the parameters under study, the coefficients of the experiments are not important and necessary:

Let.com re-write the equations with significant coefficients:

To determine the above regression mathematical model for adequacy and inadequacy, we use the test data of the Fisher criteria.

Here,

For the results of the output parameters, we use the three factorial two-power regression mathematical model of the equation:

An analysis was made of the data obtained from the three factor mathematical regression model taking into account the necessary regression coefficients by the Student's criterion and also the results of the models tested for Fisher's adequacy.

After In order to simplify the calculations, we create a Table 3:

**Table 3:**Indicators of the Student's test can be taken from the application:

From this it follows that the regression mathematical model obtained fully characterizes the process of investigation (Table 4) and (Figure 2).
