Strength Analysis And Structure Optimization Of Front Supporter Of The Concrete Mixer Truck

Competition is fierce among manufacturers of concrete mixer trucks. Therefore, companiesinvest a lot of resources to research for improving the competitiveness of products. There are nouniform design standards for tank support structure of the concrete mixer truck, so its research,design, and optimization are in great originality. Among them, the research data of the frontsupporter are very rare. It is necessary to carry out the optimization of the front support to improvethe overall performance of the products. This reseach provides a reference for the peers.In this paper, a15m3concrete mixer truck is studied. The finite element method is in use, andstatic analysis, modal analysis, harmonic analysis and transient analysisare performed to check thesafety performance of the front support. Then the topology optimization and size optimization areapplied to find new front supports with better safety and lighter weight.In static analysis,according to the standards and literatures, four single dangerous workingconditions are identified. Compare analysis results, and then give out the most dangerouscomprehensive working condition. The results show the primarystructural is safe.Provide a researchenvironment for transient analysis and an important research area for optimization.In modal analysis,confirm that resonance does not occur and find the most sensitive parts aboutthe vibration. The frequency range isprovided to harmonicanalysis and thesensitive parts areprovided to optimization.In the harmonicanalysis, find thatfatigue failure will not occur. Andprovide time step for transient analysis.In transient analysis, finally confirm that the originalstructural is safe and the result of static analysis is overly conservative. The optimization should beused to make the structure lighter and safer.In the optimization analysis, based on the placewith the largest force in the static analysisandthe sensitive areas in modal analysis, topology optimizationand size optimizationare conductedto obtainew structures. The weight is lighter by10%and the largest force is reduced by10%.Twonew structureshave taken into account the processing costs. Finally provide them to the enterprisefor choosing from.
