Insert deformation under solution, directional deformation in details, change oritentation to the corresponding torsion axis (usually y-axis), and change coordinate system to the local cylindrical coordinate system corresponding to concealment.
The result is a unit of length.
It is the arc length of the torsion.
arc length, then customize the result, user defined result, renamed to rotation angle, coordinate system select, cylindrical group, blind coordinate system, equation is uy d (d is the diameter of the axis), output unit is angle, then the system outputs the torsion angle value.
ANSYS Stiffness Analysis Matrix.
Act 1: Explanatory header.
The numbers in the second row indicate that the file has a total of 91 rows of data, 13 rows of row pointer data, 33 rows of matrix index data, and 12 rows of data on the right.
Line 3: RSA denotes real number matrices, symmetry, group set matrices; The matrix is 12 rows and 12 columns with 33 non-zero elements. Line 4:
The output format of the pointer and index data is 114, and the output format of the matrix y and the right item element is row 5: the right item is all stored, with a total of 1 column and 12 rows.
This is followed by 13 rows of row and column pointer data, 33 rows of matrix row index data, 33 matrix elements, and 12 right item data.

Anonymous users2024-02-09Since you're doing 1 to 4 models, then the principle of this application is geometric symmetry.
If we do not limit the displacement in the X direction, then there is a possibility that the displacement in the X direction will occur. And because the structure is symmetrical, the displacement should also be symmetrical (if the load is symmetrical). Then the displacement in the x-direction can only be 0.
in order to meet the requirements. So set the displacement constraint in the x-direction to 0The same applies to the constraints below.
Just changed the x-direction to the y-direction.
If you build the whole ring, infer it from your 1 4 ring. Then you don't need to set a displacement boundary condition. All you need to do is apply the load. Because there is only internal pressure, the load is symmetrical. The system is also stationary.
Don't feel inferior, in fact, everyone has advantages, it's just that you find the advantages of others, it's just that the topics discussed by others are what you're good at, and you don't understand, in some way you can also make others speechless, except for watching the news more, and asking for advice if you don't understand, slowly you will gain a lot of knowledge and a lot of experience, I hope mine will be you.
I'm original) to tell you, the strength of the thigh is the most important, the strength of your thigh has gone up, I don't believe that your upper body is still thin, and there are many reasons why the breakthrough is always cut off, not necessarily because the strength is not good, just practice dribbling. The strength of the thigh is too important, athletes who practice track and field have to squat on the barbell since childhood, that is, the strength of the legs, the strength of the legs is the source of your explosiveness and speed, you have trained the strength of the thighs, and then the strength of the upper body is twice the result with half the effort, believe me, that's right, and you have trained the strength of the legs, but also reduce your chance of injury, because the developed muscles can protect the bones, and there is a confrontation in basketball, and the confrontation is the strength of the **? Or the strength of the thighs, so, let's train the thighs well, mainly train the quadriceps muscles of the thighs, how to practice? >>>More
If you really want to exercise your body well, and exercise a tall, well-proportioned, strong, capable, chic, and beautiful body, based on my personal experience, I recommend you to take the following methods to strengthen your body: >>>More
What is the necessary connection between this and that? That's predestined.
Most of the high school writers write about ** and the like. For discussions, you can categorize some arguments (that is, some examples), look at some more materials, and think for yourself. >>>More
