1、某中型货车车架的设计III摘要根据设计参数，完成了中型货车车架设计，利用UG软件建立了主纵梁、横梁模型，及纵梁与横梁通过铆钉连接。本说明书涉及了现阶段载货汽车技术的发展趋势，以及国内外载货汽车车架的发展状况；说明书还详细阐明了中型载货汽车的方案论证：车架的设计要求、车架结构的确定、车架宽度的确定、车架纵梁形式的确定、车架横梁形式的确定、车架纵梁与横梁连接形式的确定、车架的受载分析以及车架的强度计算。在计算时把车架简化成为一个位于支座上的静定结构，然后，用材料力学的知识对本车架进行强度计算，并且在满足应

2、力要求的条件下来确定车架纵梁的断面尺寸。关键词：中型货车、车架、设计IIIAbstractAccordingtothedesignparameters,thedesignofthemediumtruckframeiscompleted,andthemainlongitudinalbeamandthebeammodelareestablishedbyUGsoftware.Thispaperinvolvesinlatelythetechnologydevelopmenttrendoftruckaswell
