Automobile back door pneumatic supporting rod arrangement design optimization method

Abstract

The invention relates to the technical field of automobile structure design optimization methods, in particular to an automobile back door pneumatic supporting rod arrangement design optimization method. The method comprises: setting an air supporting rod optimization area; screening an air supporting rod optimized area based on a set air supporting rod manufacturability condition to obtain a manufacturability optimized area meeting the air supporting rod manufacturability condition; screening the manufacturability optimized area based on a set low-temperature initial closing force condition to obtain a low-temperature closing optimization area meeting the low-temperature initial closing force condition; screening the low-temperature closing optimization area based on a set normal-temperature opening and closing condition to obtain a normal-temperature optimization area meeting the normal-temperature opening and closing condition; and screening the normal-temperature optimization area based on a set air supporting rod force value range, the back door self-closing potential energy and the back door operating force, obtaining a final optimization area to obtain an optimal solution, and obtaining optimal design parameters based on the optimal solution. The method is extremely simple and efficient, and has a great popularization value.

Description

technical field [0001] The invention relates to the technical field of an automobile structure layout design optimization method, in particular to an automobile back door pneumatic strut layout design optimization method. Background technique [0002] The operability of the back door is an important part of the convenience of opening and closing parts of passenger cars. It directly affects the important factors of customer purchase and subsequent brand recognition. Major OEMs have devoted a lot of energy to research and improve the operation of products. Comfort, to enhance the competitiveness of its products. Therefore, it is urgent to establish a key technology to improve customer control comfort and perception experience, and enhance product soft power and brand image. [0003] Traditional rear door maneuverability optimization idea: according to the CAS surface of the modeling output, arrange the gas struts, and then calculate the maneuverability according to the EXCEL ...

Problems solved by technology

[0004] According to this method, there are two disadvantages: 1. The optimal solution cannot be obtained by EXCEL calculation, and the optimization direction is not clear. Exhaustive + empirical layout is adopted, which affects the shape, body structure and man-machine layout, and the adjustment target and direction are not clear; 2. The layout efficiency is low, and the operability is adjusted and optimized while testing. If the target is not met, the time to change the best plan will be delayed
