This paper explores the improvements of inerter-based vibration absorbers on the performance of balanced suspension in multiaxle heavy-duty vehicles. A traditional integral balanced suspension is employed and the random pavement input is used to evaluate the performance of the balanced suspension. Four inerter-based mechanical networks are adopted to replace the damper in the conventional balanced suspension to improve ride comfort and handling stability. Then, by solving related optimization problems, the optimal parameters of the components in the vibration absorber can be obtained. Based on these optimization results, the main findings are listed as follows: the ride comfort and suspension travel acceleration performance are both improved, and the dynamic tire load performance remains almost unchanged compared with the traditional balanced suspension; besides, the addition of one spring and one inerter to a traditional vibration absorber provides better performance than adding only one inerter.
