Engine modular oil pan design method and system

Abstract

The invention discloses an engine modular oil pan design method which comprises the steps: dividing an oil pa into a plurality of sets of oil pan modules according to the requirement for the oil pan;dividing the attribute of each oil pan module into a plurality of oil pan characteristic families; defining different oil pan characteristics under each oil pan characteristic family according to therequirements of each oil pan module; establishing a one-to-one correspondence relationship between each oil pan feature and the part; establishing a supply code, determining an oil pan module corresponding to the supply code according to the demand of the supply code for the oil pan, and selecting oil pan features corresponding to the supply code from an oil pan feature family corresponding to theoil pan module to obtain an oil pan feature combination; obtaining an adaptive part list according to the oil pan feature combination, and obtaining the oil pan corresponding to the supply code according to part assembly on the part list. The invention further discloses an engine modular oil pan design system. Design errors can be reduced, and design efficiency is improved.

Description

technical field [0001] The invention relates to an engine, more specifically, it relates to a design method and system for an engine modularized oil pan. Background technique [0002] The detailed structure of the traditional engine oil pan uses one oil pan assembly for one supply code, and one oil pan assembly needs to be designed for each engine oil pan supply code. Such as figure 1 The structure shown is that each engine oil pan supply code corresponds to an oil pan assembly. For example, the designer combines the parts that need to be used together according to the state requirements of the A supply code to design an oil pan assembly. In other words, part 1, part 2 and part 3 are combined together to form A oil pan assembly. The traditional design method is that the designer directly faces the specific parts (parts 1 to 9 in the figure), and needs to select the matching parts corresponding to the supply code among many parts. [0003] The traditional design method has...

AI Technical Summary

Problems solved by technology

[0003] The traditional design method has the following problems: Since the designer is faced with the drawings or objects of specific parts, he needs to be very familiar with the details of each part, and it is easy to confuse parts with similar shapes and cause mismatches. configuration, low design efficiency and high requirements for designers
