constraint create joint translational

2. Normally, entity names like the joint name are composed of alphabetic, numeric, or '_' (underscore) characters, and start with an alphabetic or '_' character. They may be any length. For more information, see Using Extended Names. By enclosing the name in double quotes, you may use other printable characters, or start the name with a numeral. If a name contains characters, or starts with a numeral, you must always quote the name when entering it. Note that you can specify the parentage of an entity (for example, what part "owns" a marker or a geometry element) when you CREATE it by changing the name. If you enter just the entity name, then the default parent will be assigned by Adams View. If you type in the full name, then you may over ride the default parent. In most cases, when creating an entity, Adams View will provide a default name. The default name that Adams View provides will specify the parentage that it has assumed. You may, or course, delete this name and use your own. The form of a full name is:

3. When you use the FILE ADAMS_DATA_SET WRITE command, Adams View writes an Adams data file for your model. Adams requires that each modeling element be identified by a unique integer identifier. If you use this parameter to specify a non-zero identifier, Adams View will use it in the corresponding statement in the Adams data file. You may also enter zero as an identifier, either explicitly or by default. The next time you write an Adams file, Adams View will replace the zero with a unique, internally-generated identifier. Adams View will permanently store this identifier with the element just as if you had entered it yourself. Normally, you would let all identifiers default to zero, and Adams View would generate the identifiers for you. You are never required to enter a non-zero identifier. You only need to specify it if, for some reason, you wish to control the Adams file output.

4. When an Adams Solver data file (.adm) is read into Adams View, all comments associated with a statement (from the end of the previous statement through the end of the current statement) are stored with the object. Comments in the data file can be associated with model. These comments must follow the title statement and be followed by the comment 'END OF MODEL COMMENTS'. This string must be uppercase. When an Adams Solver data file is written, the comments for an object are written before the statement corresponding to the object.

5. Adams View measures the translational displacement of the origin of the I marker along the common z-axis of the I and the J markers with respect to the origin of the J marker. If you specify TRANSLATIONAL_IC, but not VELOCITY_IC, Adams View will set VELOCITY_IC to zero. Joint initial conditions impose constraints that are active only during initial conditions analysis (not at the time of the initial configuration). Adams does not impose initial conditions during subsequent analyses. If you impose initial conditions on the joint that are inconsistent with those on a part in the joint, the initial conditions on the joint have precedence over those on the part. However, if you impose initial conditions on the joint that are inconsistent with imparted motions on the joint, the initial conditions as specified by the motion generator have precedence over those here.

6. Setting the no_translational_ic is not the same as setting the value to zero. A zero velocity is not the same as "no" velocity. Therefore, by setting this parameter to true there is no longer a velocity initial condition for this element.

7. Adams View measures the translational velocity of the origin of the I marker along the common z-axis of the I and the J markers with respect to the origin of the J marker. If you specify VELOCITY_IC, but not TRANSLATIONAL_IC, Adams View will set TRANSLATIONAL_IC to zero. Joint initial conditions impose constraints that are active only during initial conditions analysis (not at the time of the initial configuration). Adams does not impose initial conditions during subsequent analyses. If you impose initial conditions on the joint that are inconsistent with those on a part in the joint, the initial conditions on the joint have precedence over those n the part. However, if you impose initial conditions on the joint that are inconsistent with imparted motions on the joint, the initial conditions as specified by the motion generator have precedence over those here.

8. Setting the no_velocity_ic parameter is not the same as setting the value to zero. A zero velocity is not the same as "no" velocity. Therefore, by setting this parameter to true there is no longer a velocity initial condition for this element.

9. The height and the width values should be a real number between 0.0 and 2.0, where 2.0 represents the height of the Adams View window. Therefore, a value of 1.0 will set the info window to be one half as high as the Adams View window.

10.  By default, you supply Cartesian (x, y, z) coordinates for the location parameter. You may use the 'defaults units coordinate_system_type =' command to change this convention. For example, selecting 'cylindrical' means you will subsequently be supplying r, theta, and z coordinates. Adams View applies your location coordinates in the coordinate system you identify with the RELATIVE_TO parameter. The default for the RELATIVE_TO parameter is the default coordinate system. (See the RELATIVE_TO parameter for this command).

11.  Adams View will orient the coordinate system by starting from the initial coordinate system and applying three successive rotations. Depending on the convention you have selected, the rotations may occur about space-fixed or bodyfixed axes in any meaningful combination of the x, y, and z axes.

12.  For the along_axis_orientation parameter you may enter either one or two locations to direct the axis. If you enter one location, the axis will point toward the location. If you specify two locations, the axis will be parallel to, and pointing the same way as, the vector from the first location to the second. Note that this does not completely dictate the orientation of the coordinate system. Adams View will osition the coordinate system with an arbitrary rotation about the axis. If you must completely control the coordinate system orientation, use ORIENTATION or IN_PLANE_ORIENTATION. By default, you direct the Z axis of the coordinate system.

13.  For the in_plane_orientation parameter you may enter either two or three locations. If you enter two locations, the axis will point toward the first location and the plane will fall on the second. If you specify three locations, the axis will be parallel to, and pointing the same way as, the vector from the first location to the second and the plane will be parallel to the plane defined by the three locations. By default, you direct the Z axis of the coordinate system and locate the ZX plane. You may use the 'DEFAULTS ORIENT_AXIS_AND_PLANE AXIS_AND_PLANE_SETTING=' command to change this convention. For example, selecting X_AXIS_XY_PLANE means you will subsequently be directing the X axis and locating the XY plane. Adams View applies your location coordinates in the coordinate system you identify with the RELATIVE_TO parameter. The default for the RELATIVE_TO parameter is the default coordinate system.

14.  If the relative_to parameter is not specified, the default coordinate system is used. The default coordinate system is initially your model, that is, the global coordinate system. You may change the default coordinate system using the 'defaults coordinate_system' command.
