Fault mode visual method based on three-dimensional model of product

Abstract

The invention discloses a fault mode visualization method based on a three-dimensional model of a product. The method comprises four steps of: step 1. carrying out blocked partitioning and cuboid configuration on the three-dimensional model aiming at a complex product; step 2. collecting relevant information of a fault mode, analyzing a potential fault mode and a fault reason of the complex product and component parts at certain one technical state, obtaining an harsh degree and an occurrence probability grade, and obtaining a space coordinate of a fault mode generating position relative to the origin of coordinates and design and improvement measures corresponding to the fault mode according to the position of the product in a three-dimensional coordinate; step 3. carrying out visual modeling on the fault mode information; and step 4. carrying out a method for analyzing space fault intensity. The space fault intensity is defined, members with relatively high fault intensity are determined, and thus the fault is eliminated by designing corresponding improvement measures and use compensation measures and repairing assurance resource information, and finally the effectiveness verification is implemented. The method has a good application prospect in the technical field of product design.

Description

technical field [0001] The invention relates to a failure mode visualization method based on a product three-dimensional model during the realization process of complex product reliability design. This method uses information visualization technology to visualize the failure modes and their impact analysis results, which were originally limited to text reports, and integrate them into the three-dimensional model of the product, thereby providing clear and intuitive information for the display and decision-making of reliability design results, and targeting at faults. Mode information takes corresponding countermeasures and improvement measures in the complex product RMS realization process. The invention belongs to the technical field of product design. Background technique [0002] Accurate identification and analysis of faults is the basis for reliability design. However, in conventional failure mode analysis work, such as failure mode and effects analysis (FMEA), the re...

Problems solved by technology

However, in conventional failure mode analysis work, such as failure mode and effects analysis (FMEA), the results often exist in the form of textual materials such as reports, and there are some disadvantages in the understanding and analysis of fault information in textual form.

This is because in the process of failure mode analysis, the previous analysis information mainly comes from some product designs, process data, test procedures, failure mode effects and hazard analysis (FMECA) or failure mode and effects analysis (FMEA) reports and faults. However, designers have low efficiency in obtaining text-based information, and it is not easy to find the internal connection between information. For example, it is difficult to understand the specific location of the product failure mode literally, and it is impossible to understand intuitively literally. Distribution of failure modes in the product, etc.
