重型车辆造成的道路损坏是世界范围内面临的一个严重问题。本文研究了将惰性元件集成到卡车悬架系统中减少道路损坏的潜力。最初，在频域中研究了具有两种低复杂性基于惯性的线性悬架布局的四分之一车、俯仰平面和滚转平面模型。与传统的平行弹簧阻尼器卡车悬架布局相比，确定了每种型号 J95 道路损坏指数的降低。还表明，所提出的悬架能够增强侧倾稳定性，同时将道路损坏保持在给定水平。随后，将板簧所体现的力与位移之间的非线性关系纳入俯仰平面和滚转平面时域模型中。这些证实了基于惯性的悬架布局在减少道路损坏方面的潜在优势。
Road damage caused by heavy vehicles is a serious problem experienced worldwide. This paper investigates the potential for reduction in road damage by incorporating the inerter element into truck suspension systems. Initially, quarter-car, pitch-plane and roll-plane models with two low-complexity inerter-based linear suspension layouts are investigated in the frequency domain. Reductions of the J95 road damage index for each model are identified against conventional parallel spring–damper truck suspension layouts. It is also shown that the proposed suspensions are capable of enhancing the roll stability while keeping the road damage at a given level. Subsequently, the nonlinear relationship between force and displacement as manifested by leaf springs is incorporated into the pitch-plane and roll-plane time-domain models. These confirm the potential advantage of inerter-based suspension layouts for road damage reduction.
