- Abstract
- In this paper, the dynamic characteristics of the in-arm type hydropneumatic suspension unit (ISU) of armed tracked vehicle are theoretically analyzed and numerically investigated. Accurate spring and damping models are introduced and combined to secure the analysis reliability. One is the Benedict-Webb-Rubin equation of state which is adopted to model the spring behavior of real nitrogen gas in ISU system. The other describes the behavior of a damper during four distinct ISU motions; jounce-loading, jounce-unloading, reboundloading and rebound-unloading. For the comparison purpose, the numerical results of the dynamic behavior of ISU system using a real gas model and two ideal gas models are presented and compared.
