重型清障车吊臂和托臂的优化设计及应力分析

清障车是一种具有道路抢险作业装备,能够起吊和托起事故、违章或损坏车辆,并能快速离开事故现场的专用车辆。文章采用UG软件对吊臂模型处理,通过其自带软件NX NASTRAN对托臂总成进行有限元分析,根据实际作业工况对托臂总成进行约束与载荷施加,使托臂的强度分析更具有可信度。其结果为吊臂和托臂总成的设计及优化提供了参考依据。

Optimized Design Heavy Wrecker Boom and the Carrier Arm and Stress Analysis

The wrecker is a kind of road rescue operations equipment, capable of lifting and hold accidents, illegal,or damage to the vehicle,and quickly left the scene of special vehicles. Base model using UG soft-ware to handle the boom, comes with software by NX NASTRAN for the carriage arm assembly finite ele-ment analysis, according to the actual working condition of the bracket arm assembly constraints and load is applied, the strength of the supporting arm of analysis more credibility. As a result,the boom and the carrier arm assembly design and optimization provides a reference for.
