摘要
行间运输车在不平坦的丘陵山地果园路面行进时,会因减振性能差而出现果品损伤情况。为了减少运输过程中的水果损伤,需对行间运输车减振系统进行优化。根据山地果园地形地貌,构建了行间运输车路面激励图谱,并通过对减振系统进行分析,设计了一种适用于山地果园行间运输车的三级减振结构。利用Adams构建多体动力学模型,对减振性能仿真分析,结果表明:山地果园行间运输车较现有运输小车减振结构在C、D等级路面上Z向减振性能分别优化了6.4%和19.6%,在正负向减振性能优化了18.4%和17.7%,优化后的运输车较现有运输车具备更好的稳定性和减振性能。
Fruit will be damaged when the inter-row transport vehicle travels on uneven hilly orchard roads with its poor vibration damping performance.In order to reduce fruit damage during transportation,it is necessary to optimize the vibration damping system of the inter-row transport vehicle.According to the topography of the mountain orchard,it is constructed that the road surface incentive map of the inter-row transport vehicle.A three-level damping structure is suitable for inter-row transport vehicles in mountain orchards.It is designed by the analysis of its damping system.Multi-body dynamics model is established and simulated by adams.And its vibration damping performance is analyzed.The results show that the damping performance of the inter-row transport vehicle more than that of the existing transport trolley by 6.4%and 19.6%in the direction of z axis and by 18.4%and 17.7%in positive and negative directions of x axis on class c and class d road.The stability and damping performance of the optimized transport vehicle is better than that of the existing transport vehicle.
