摘要
为提高复合材料注塑件的仿真准确性,基于多尺度联合仿真方法,以汽车发动机正时链条导轨为例,根据导轨纤维配向以及结构应力分布情况,设计了导轨减量化结构,在保证整体应力水平在安全范围内的同时,最大应力降低了12%,质量减轻了4%,实现了汽车发动机正时链条导轨的减量化设计。
Reduction design is an effective way to realize the effective utilization of plastic product resources and the pre‐vention and control of pollution sources.However,traditional simulation methods cannot accurately express the material properties of composite injection‐molded parts.To improve their simulation accuracy,we designed a guide‐rail‐reduction structure to ensure that the overall stress level is within a safe range according to the fiber orientation and structural stress of the guide and the distribution situation.This design was based on a multi‐scale co‐simulation method with the timing chain guide rail of an automobile engine as an example.With this design,the maximum stress was reduced by 12%and the mass was reduced by 4%.This realizes the reduction design of the timing chain guide rail of the automobile engine.
