Embodiment Construction

[0016] refer to figure 2 The present invention will be described in detail.

[0017] This example is a volume measurement of a certain type of chemical reaction kettle. Many similar structures are omitted in the figure, and the reaction kettle has an elliptical interface. Firstly, use UG, autoCAD, Pro / E and other three-dimensional modeling software to construct a three-dimensional model of the container, in which the three-dimensional model of the container body is an assembly composed of parts, and the parts include feeding port 1, discharging port 2, stirring Device 3, container cover 4 and container body 5. Convert the components in the assembly environment to the part environment as a whole, and keep the assembly position relationship of the components unchanged, and obtain the part model in the part environment corresponding to the assembly in the assembly environment.

[0018] Step 1. Construct the three-dimensional model of the shell, container cover, bulkhead, wave ...

Abstract

The invention discloses a complex internal-space container volume measurement method, and solves the technical problem of low measurement precision by the existing complex internal-space container volume measurement method. According to the technical scheme, the method includes firstly performing assembly modeling of constituent components of a complex internal-space container through CAD (computer aided design) software; filling holes on the surface of the complex internal-space container to be entities; hiding internal structure of the complex internal-space container; performing Boolean summation of the processed components; obtaining sealed complex internal-space container component without internal structure; transferring sealed curved-surface inside to be an entity through trimming a complex internal-space container bounding box; obtaining the volume of the complex internal-space container without the complex internal structure; displaying the internal structure, and measuring the precision volume; finally obtaining the volume of the complex internal-space container by taking the obtained complex internal space total volume to substract the volume of the complex internal structure. Measurement precision of the complex internal-space volume is improved.

Description

technical field [0001] The invention relates to a method for measuring the volume of a container, in particular to a method for measuring the volume of a container in a complex inner space. Background technique [0002] The chemical reactors, tank trucks and other storage containers with complex structures commonly used in engineering at present have complex internal space structures, and it is difficult to accurately measure their volumes by traditional measurement methods. When designing a container with a complex internal space, it is very important to obtain its volume accurately. The measurement of the container volume is the first step in volume optimization and analysis. The deviation of volume measurement will not only bring economic losses to the enterprise, but also affect the Therefore, it is of great practical significance to ensure the accuracy of the container volume. At present, most enterprises use CAD software to design the container body. The volume calcul...
