Abstract

In this paper, weight reduction methods were studied in a seat track used in a passenger cars front seats. One of front seat, which has passed regulation tests and has been verified by the finite element model, a monoblock riser bracket design has been developed instead of the existing individual brackets. The bracket geometry has determined by topography optimization. The final model was created by updating the design of the resulting model in terms of manufacturability. Finite element analyses were performed in Altair HyperWorks according to the regulation conditions. The design was validated in static and dynamic tests, including crash tests. Comparing with the existing parts, 26.7% weight has been reduced as a result of the study.

摘要

在本文中，研究了用于乘用车前排座椅的座椅轨道的减重方法。其中一款前排座椅已通过法规测试并通过有限元模型验证，开发了一种整体式立管支架设计，而不是现有的单个支架。支架几何形状已通过地形优化确定。最终模型是通过在可制造性方面更新最终模型的设计来创建的。根据规定条件在 Altair HyperWorks 中进行有限元分析。该设计在静态和动态测试中得到验证，包括碰撞测试。与现有零件相比，研究结果减轻了 26.7% 的重量。
