乘用车一级消声器固定支架耐久性优化设计

Passenger Cars Exhaust Silencer packing block Durability Optimized Design

文章以提高某款乘用车排气一级消声器固定支架使用寿命为例,通过对支架的材料、厚度、槽型梁结构的分析;结合实车具体情况进行优化,提升支架的使用寿命。通过Hyper Works验证支架的应力集中情况和位移大小,理论验证该方案的可行性。通过路试试验,实车验证了该方案的效果,结果表明:排气系统一级消声器支架优化有效。

Article with a certain exaltation multiply to exhaust with the car silencer of packing block service lives for instance,pass the material to the packing block,thickness and slot type girder the analysis of structure;Combine concrete condition progress of solid car excellent turn,promote the service life of packing block;Pass Hyper Works the stress concentration of verification packing block conditions and displacement dimension,the theory verifies the feasibility of the scheme;Try to the road tries test,the solid car verifies the effect of the scheme,result enunciation:Exhaust one stage silencer the packing block Be excellent to turn be available.
