Evaluation method for the positional comfort of parts in the sub-dashboard area

Abstract

The present invention provides a method for evaluating the positional comfort of parts in the sub-instrument panel area. Wherein, it includes the following steps: a. establishing a mathematical model of the sub-instrument panel area parts, wherein, according to the mathematical model, the sub-instrument panel area parts are converted into a solid model at a size ratio of 1:1; b. Position the driver's seat and the parts of the sub-instrument panel area. The advantages of the present invention include: in the development stage of the passenger car, it provides a method for evaluating the comfort problem of the parts in the sub-instrument panel area at each arrangement position, the evaluation method is accurate, efficient and low in cost, and helps to improve the sub-instrument panel. The comfort of regional parts promotes the improvement of the quality of passenger car development.

Description

technical field [0001] The invention relates to the field of design and development of passenger cars, and more specifically, to a method for evaluating the position comfort of parts in the sub-dashboard area of ​​passenger cars. Background technique [0002] The sub-dashboard of a passenger car is a high-focus area for drivers. Armrests, brake handles, cup holders, and shift handles on the sub-dashboard are all frequently used and operated parts by the driver. The relative positional relationship between these parts and the driver, and the relative positional relationship between the parts will affect the operating comfort. , these issues are directly related to the ergonomic performance of the vehicle, thus affecting the objective quality and market competitiveness of the vehicle. Therefore, assessing and validating the integration of parts on these console panels and their placement is an important part of the passenger car development process. [0003] At present, ther...

Problems solved by technology

The virtual evaluation is based on the analysis of the position coordinates of the parts, the position layout of the 3D digital model, and the analysis combined with the 3D virtual environment. This evaluation method lacks the real feeling of the operator, such as the sense of hand touch, operating strength and arm stretching state. , unable to give a direct and real comfortable operating experience

Physical evaluation is to obtain an intuitive operating comfort experience through the actual operation evaluation of real vehicles and engineering parts of existing models on the market, but this evaluation method will take a lot of time and money, and it is impossible to accurately obtain all parts Needed assessment location
