摘要
针对惯容在研究中本体质量常被忽略的问题,基于一类滚珠丝杠惯容,提出了一种考虑惯容本体质量的端口质量模型。建立了基于滚珠丝杠惯容的一阶系统和二阶系统数学模型和虚拟样机仿真模型,通过对比数学模型和虚拟样机仿真模型的频率响应,并通过台架试验,证实了所提出的惯容端口质量模型的有效性。进一步,基于1/4车辆悬架模型,分析了惯容本体质量对乘坐舒适性的影响,对比分析了考虑和不考虑本体质量两种情形下的系统性能。优化仿真结果表明,考虑本体质量和不考虑本体质量两种情形下系统性能存在一定差异,且基于端口质量模型的优化结果可进一步提升系统舒适性,说明了考虑惯容本体质量的必要性以及所提端口质量模型的有效性。
In terms of the fact that the physical mass of inerters is often ignored in the existing research,a port-mass model for ball-screw inerters with physical mass consideration was proposed.The mathematical models and virtual simulation prototypes of a first-order system and a second-order system with a ball-screw inerter were established.By comparing the frequency responses of the mathematical model and simulation model,and through bench experiments,the accuracy of the proposed port-mass model was verified.Furthermore,based on a quarter-car vehicle model,the influence of the inerter physical mass on ride comfort was analyzed.The optimization simulation results show that there is an apparent difference in system performances between the cases with and without the physical mass consideration.Moreover,the optimization results indicate that comfort performance can be further improved based on the port-mass model.This demonstrates the necessity of considering the physical mass of inerters and the effectiveness of the proposed port-mass model.
