轿车车门制造质量对装配质量影响的分析研究

对影响装配质量的关键部件车门的加工质量进行了详细的统计分析，分析了安装密封条前后车门外板在X向和Y向的变形情况。分析结果表明，车门制造精度与理论值相比存在着较大的差距，需要进行工装调整。车门在安装密封条前后在X向和Y向存在着较大的变形，说明车门的刚度存在着薄弱环节。这对控制轿车车门装配质量有着重要的理论指导意义。

Modular route bus design – A method of meeting transport operation and vehicle manufacturing requirements

This research examines the problem of route bus specification and vehicle manufacturability. In order for bus operators to provide transport services, a range of vehicle configurations must be available from bus manufacturers, generating variety which has a negative impact on the manufacturing process. Larger part inventories, uncontrolled labour tasks and more troublesome maintenance are known impacts of this variety. This research identifies the functional necessities in route bus interior design and reduces the problems in bus manufacture and operation caused by specification diversity by proposing a modularised system of bus design. In particular, it makes recommendations as to how bus configuration should be carried out, ensuring an optimum mix of operational and manufacturing needs:

• 1.Determine user needs before the bus specification process.
• 2.Designs to be developed by the manufacturer in response to user needs.
• 3.This design should be standardised where possible, as suggested by the user needs.
• 4.Where user needs dictate product variations, apply a mass customisation approach to accommodate these needs.

The recommendations are communicated in design proposals for a modular bus interior, demonstrated by four cases designed to meet the present status quo of bus interior design and predictions for the future of the field.
