A method of analyzing parts information using a parts information analysis system with reference to FIG. 2 is as follows.

First, the operation unit 110 selects at least one component that needs to be analyzed from the first database 120 (S110).

The part may be selected from a list in which name and mass information are collectively stored, or a list may be selected from several lists formed by collecting similar parts and then the part may be selected from the list. By selecting the part, the operation unit 110 may obtain the name and mass information of the part.

Next, the operation unit 110 obtains 3D design information corresponding to the selected part from the second database 120 (S120).

A specific method for obtaining 3D design information corresponding to the selected part by the operation unit 110 with reference to FIG. 3 is as follows.

First, the calculation unit 110 matches the part selected from the first database 120 with 3D design information corresponding to the part in the 3D design information of the second database 130 (S121).

For example, a code is assigned to each part name and mass information stored in the first database 120, and a code is assigned to 3D design information of each part stored in the second database 130, respectively. At this time, the same code may be assigned to the same part. Examples of the code may be the name of the part, a series of numbers, a series of letters, or a mixture thereof. The matching may be performed by selecting the 3D design information that matches the code assigned to the name and mass information of the part selected from the first database 120 from among codes respectively assigned to the 3D design information of the part.

Since the matching is automatically performed by the code, the time required for the matching can be shortened. In addition, since the operator may not intervene in the matching, it is possible to improve the reliability of the matching by preventing a matching error by the operator.

When the matching is completed, the operation unit 110 extracts 3D design information corresponding to the part from the second database 130 (S122).

The operation unit 110 may check the dimensions and volume of the part by using the extracted 3D design information.

When the mass information of the part and the 3D design information of the part are obtained, the operation unit 110 obtains the center of gravity and the moment of inertia information of the part by using the mass information of the part and the 3D design information of the part. S130)

A detailed method of acquiring information on the center of gravity and moment of inertia of the part with reference to FIG. 4 is as follows.

First, the calculation unit 110 calculates the initial mass of the part by applying the density of the reference material using the 3D design information of the part obtained from the second database 130 (131)

The volume of the part can be calculated by checking the dimensions of the part from the 3D design information of the part. In the 3D design information, there is no information on the material constituting the part. Accordingly, since the density of the reference material is applied to the part and the volume of the part can be known, the initial mass of the part can be calculated. Various materials may be used as the reference material. For example, the reference material may be water. That is, the initial mass may be a mass when the part is made of water.

The virtual density of the part is calculated using the mass information of the part, the density of the reference material, and the initial mass information. (132)

Since the calculation unit 110 knows the mass information of the part and the density of the reference material, and can calculate the initial mass information, when the part has a mass stored in the first database 120, the part is The virtual density of can be calculated.

The center of gravity and the moment of inertia of the part are calculated using the virtual density of the part (S133).

The calculation unit 110 may mathematically calculate the moment of inertia as well as the center of gravity of the part by using the calculated virtual density of the part, the previously obtained mass information of the part, and 3D design information.

Next, the calculated center of gravity and moment of inertia information of the part is updated in the first database (S140).

The calculation unit 110 transmits and stores the calculated center of gravity and moment of inertia information of the part to the first database. Accordingly, the center of gravity and the moment of inertia information may be added to the name and mass information of the part stored in the first database 120. That is, the name, mass, center of gravity, and moment of inertia information of the part may be stored in the list.

Meanwhile, the calculation unit 110 may display the calculated center of gravity and moment of inertia information of the part together with the name and mass information of the part. Therefore, the user can easily check the result.

According to the part information analysis method, 3D design information of the second database 120 corresponding to the part selected from the first database 120 may be automatically matched. Therefore, it is possible to reduce the time required to check the center of gravity and the moment of inertia information for the part, and since the operator does not intervene in the matching, the reliability of the center of gravity and the moment of inertia information can be improved.

As described above, according to the part information analysis method, information on the center of gravity and moment of inertia for the part may be checked by automatically matching 3D design information in the second database corresponding to the part selected in the first database. Accordingly, the time required to check the center of gravity and the moment of inertia information can be reduced, and reliability of the center of gravity and the moment of inertia information can be improved.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the following claims. You will understand that you can.
