Application of Computer Aided Engineering in the Design of Heavy-Duty Truck Frames

ABSTRACT
In recent years the heavy-duty Class 8 truck market has become very focused on weight and cost reduction. This represents a major challenge for design engineers since these vehicles are used in a wide variety of vocations from highway line haul to logging in severe off-road environments.
The challenge is to meet the weight and cost reduction goals without sacrificing durability and performance. This paper discusses the integration of computer aided design and engineering software codes (Pro/Engineer,ADAMS, and ANSYS) to simulate the effect of design changes to the truck frame .In particular, this paper discuses the development of an ADAMS multi-body dynamics model of a full truck and trailer to simulate vehicle handling, roll stability, ride performance, and durability loading. The model includes a flexible frame model using a component mode synthesis approach with modes imported from a finite element analysis program. The link between the multi-body simulation and the finite element code is also used to transfer loads back to the finite element model for stress analysis. Tight links between all the codes ensures that new design iterations can be quickly evaluated for concurrent design and analysis. A detailed case study showing how this technology has been used is also included.

辅助工程设计重型货车车架
摘要：
近年来，重型货车市场变得非常的注重重量和降低成本。这对设计工程师是重大挑战，因为这些车辆被用在各种各样的公路环境，从高速公路到严重的越野环境。目前的挑战是在不牺牲耐用性和性能降低的前提下满足质量和成本。本文论述了运用计算机集成、计算机辅助设计和工程软件代码（Pro / Engineer，ADAMS软件和ANSYS）来辅助设计更改车架。
特别是，本文集中论述了一个ADAMS多体动力学模型，一个完整的卡车和拖车来模拟车辆的侧翻稳定性，平顺性，和耐久性载荷。该模型包括一个采用灵活的框架模型模态综合模式，探讨了有限元分析程序。之间的多体仿真链接与有限元程序也可以用来传输、加载应力分析有限元模型。所有代码之间紧密连结，确保新的设计并行计算可快速用于设计和分析。一个说明这是如何
已被使用的技术详细的个案研究也包括在内。
