Problems solved by technology

[0003] At the current stage, the structural design process of the automobile body-in-white is to design first and then simulate. Unreasonable structural design can only be found in the later simulation, and then the structural design is modified before simulation
If the body-in-white lightweight is modified after the concept stage, the structure is modified for lightweight, and the simulation needs to be re-simulated, which prolongs the entire development time

Abstract

The invention discloses a lightweight analysis method for an automobile body-in-white in a concept stage. The method comprises the following steps of: performing grade division on a vehicle according to a vehicle wheelbase, and determining a grade corresponding to the researched and developed vehicle; determining a target lightweight coefficient reference value at the same grade as the researched and developed vehicle from a competitive product lightweight coefficient database, wherein the competitive product lightweight coefficient database is used for storing the grade of a competitive product vehicle and the lightweight coefficient reference value corresponding to each grade; calculating a lightweight coefficient of the research and development vehicle; and if the lightweight coefficient is greater than a target lightweight coefficient reference value, performing lightweight processing on a current vehicle body model of the researched and developed vehicle. The method enables the lightweight design of the body-in-white in the concept stage to reach a reasonable target, and reduces the possibility of later structure change.

Description

technical field [0001] The invention belongs to the field of automobile research and development, and in particular relates to a method, system, computer storage medium and computer equipment for performing lightweight analysis on automobile body-in-white at the conceptual stage. Background technique [0002] Vehicle weight is directly related to energy consumption, exhaust emissions and collision safety regulations. Based on various considerations, vehicle weight is required to be continuously reduced. Therefore, vehicle lightweight technology has become a research hotspot in the industry. [0003] At the current stage, the structural design process of the automobile body-in-white is to design first and then simulate. Unreasonable structural design can only be found in the later simulation, and then the structural design is modified before simulation. If the body-in-white is lightweight after the conceptual stage, and the structure is modified for lightweight, re-simulation...
