CRASHWORTHINESS AND LIGHT WEIGHT DESIGN OF BODY IN WHITE BASED ON HIGH STRENGTH STEEL AND FILLING MATERIALS
Structure of vehicle body is designed to absorb kinetic energy,transform impact force and keep survival space during crash. Light weight design of BIWcan realize better power performance and fuel economy,decrease exhaust emission. In this paper,collision of vehicle body structure is decomposed into axial crushing and transverse bending. Thin walled structure’s ability inenergy absorption and bending resistanceis researched,which is based on high strength steel and different filling materials. After applied the research conclusion in a SUV’s body optimization,the crash simulation result shows that it improved passive safety and reduced body weight effectively
Configuration Design and Parameter Model for Flexible
设计了一种弹性喷嘴的变量喷头,其喷嘴直径随压力的增大而变大,从而降低喷头的雾化程度。为研究确定弹性喷嘴锥形角、喷嘴直径、末端圆柱段长度、弹性材料厚度和喷嘴伸出量等主要参数,利用ANSYS建立了变量喷头及其内流道的三维实体模型,采用k-ε模型在CFX和ANSYS单向流固耦合中模拟喷头弹性喷嘴在不同工作压力,不同喷嘴直径组合下的内流道流场和喷嘴的变形过程,建立了工作压力、喷嘴直径变形和喷头流量等参数的关系模型。采用全面喷洒的方法对喷头样品进行了试验,通过测量喷头流量和喷头工作压力等,对模拟结果进行验证。</span
