An inertia channel design method for a hydraulic damper specifically used in high-speed railways

This paper presents an inertia channel design methodology for a hydraulic damper dedicated to high-speed rail applications. By theoretically analyzing how dimensional parameters of the inertia channel influence the damping force of the hydraulic mount, the calculation methods for both friction losses and local losses are elaborated in detail. Integrating specific design targets, the required inertia-channel dimensions are derived. The study demonstrates that the proposed approach can markedly accelerate the design process of hydraulic dampers and substantially cut research-and-development costs.
