Erwin Hymer Group North America (EHGNA) is a major manufacturer of Class B motor homes and trailers with a production**facility in Cambridge, Ontario. To increase their market, there is a clear need to reduce vehicle weight so that a larger range of**passenger vehicles can tow the trailers. To achieve this goal, the weight of the existing structure must be reduced from**approximately 2600 lbs, to 2000 lbs. High strength light metals will be required to reach this target which inevitably leads to**complications in the manufacturing process. The selection and optimization of the joining processes of dissimilar materials is**critical to ensure that the new frame design is feasible from the perspective of assembly and in-service performance. The present**work will investigate lightweighting of the frame structure with an emphasis upon light metals including high strength 6xxx-series**aluminium extrusions and sandwich structures with a novel aluminium foam core. Numerical models of the foam and extrusions**will be generated and used to re-design the frame and achieve part consolidation. An emphasis will be placed upon the**development of the appropriate joining methodology for the aluminium foam to steel and aluminium as well as joining of the**fiberglass shell to the frame

Erwin Hymer Group North America（EHGNA）是B级房车和拖车的主要制造商，在安大略的剑桥设有生产 ** 工厂。为了扩大其市场，显然需要减轻车辆重量，以便更大范围的乘用车可以牵引拖车。为了实现这一目标，现有结构的重量必须从 ** 约2600磅减少到2000磅。高强度轻金属将需要达到这一目标，这不可避免地导致 ** 复杂的制造过程。异种材料连接工艺的选择和优化对于确保新框架设计从装配和使用性能的角度来看是可行的至关重要。目前的工作将调查轻量化的框架结构，重点是轻金属，包括高强度6xxx系列 ** 铝型材和夹层结构与一种新的铝泡沫芯。将生成泡沫和挤压件 ** 的数值模型，并用于重新设计框架和实现部件合并。重点将放在开发适当的连接方法，将泡沫铝连接到钢和铝上，以及将玻璃纤维外壳连接到框架上
