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.

装有惰化器的卡车悬架可最大程度地减少道路损坏

重型车辆造成的道路损坏是全世界都遇到的严重问题。本文研究了通过将惰性元件纳入卡车悬架系统来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度的基于惯性的线性悬架布局的四分之一汽车、俯仰平面和滚动平面模型。每个模型的 J95 道路损坏指数的减少是根据传统的平行弹簧减震器卡车悬架布局确定的。还表明，所提出的悬架能够提高侧倾稳定性，同时将道路损坏保持在给定的水平。随后，由板簧表现出的力和位移之间的非线性关系被合并到俯仰平面和滚动平面时域模型中。
