摘　　要：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。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.
