Abstract
According to the shaft torque angle with the change of torque with Matlab for a certain range of calculation.Can use the torque angle formula to find the different torque grid number and diameter of the critical value of the largest line of torque angle is calculated. Using Matlab with this formula is more suitable to find the maximum torque angle of the situation. And design shaft if there are improper will lead to the failure of the installation of parts, so the first simulation method simulation experiment will lessen the cost of manufacturing. Thus, the design cost is lessened to facilitate profitability. Easy to grasp the danger points, so that the design department quickly layout production to meet the needs of customers. The relationship between torsional angle and torque and diameter is seen from a three-dimensional perspective.

Introduction
The torque angle as an important factor has been computed in advance before manufacture to lessen failure happened in actual utility. So the solution with Matlab software is going to be calculated in the conditions of three various parameters so as to observe the optimum in this paper. The three parameters are afforded as torque, diameter and grid to simulate the torque angle. We are trying to look for the best parameter to adapt to determining the optimum of them in light of Matlab software where it can provide fast simulation result for us. That becomes the destination of this paper.The torque angle is the rigid angle generated when the rotating shaft is working. Once it stops working, it will disappear due to the rigidity recovery.However, failure can also occur due to excessive torque angle. [1~2] This test is to use Matlab software for 3D image processing data, so this paper from its torque angle generated parameters analysis to produce the maximum torque angle value, put forward parameter requirements, to prevent the failure of parts.[3~6] using Matlab data processing software to calculate the torque angle of the shaft is a performance test conducted by this software. Using different parameter torque moment ˴ grid number and diameter of the different stages. The detail discussion will be described as follow.

Discussions
As seen in Table 1 for the parameters of Matlab. When the diameter is 5~7mm, the torque angle value does not exist, but is larger when 10mm ~50mm.The torque angle reaches its maximum when the diameter reaches 10~20mm, and then lower and lower.It can be seen from these three sets of data that the torque angle decreases with the decrease of torque distance. When the minimum torque angle is 0.42°/m, the minimum diameter is 20mm and 2*105Nmm. With the increase of the number of networks, the clarity is obviously higher than the other two. Furthermore, it is gotten for different values.The minimum value is 0.42°/m, then 6.9°/m, and the maximum value is 550°/m. After calculation, it was found that the maximum torque angle was 550°/m with diameter to be 7mm, which was beyond the normal range, as shown in Figure 1 (b). It is formed with a diameter of 7mm and a torque of 2*105Nmm. It can be seen from the three-dimensional diagram whose diameter and torque are the main factors leading to the increase of torque angle. So in the design to make the diameter of the shaft it affords not too large as far as possible, and torque also need to be controlled so as not to increase the torque angle. These are the main parameters to control. Torque angle 6.9°/m with diameter to be 15mm in Figure 1 (a) and 0.42° with diameter to be 20mm in Figure 1 (c). The torque angle in Figure 1(c) is more in line with the requirements, and in Figure 1(a) the torque angle is slightly beyond the requirements.
Conclusions
- Using Matlab data processing software to calculate the torque angle of the shaft is a performance test conducted by the software. Using different parameter torque moment ˴ grid number and diameter of the different stages of test, the torque angle indicates different values.
- It can be seen from the three-dimensional diagram that diameter and torque are the main factors leading to the increase of torque angle. So in the design to make the diameter of the shaft as far as possible not too large, and torque also need to be controlled so as to lessen the torque angle.
