DYNAMIC STABILITY ANALYSIS OF A COUPLED MOVING BOGIE SYSTEM
This study explores the dynamic behavior and vibration stability of a complex moving mechanical oscillator coupled with a three-part viscoelastically connected continuous beam-foundation system. Elastic waves generated by the oscillator can destabilize the system, a scenario common in high-speed trains and vehicles. The paper presents an improved analytical approach, focusing on the effects of a variable primary stiffness suspension on vibration stability. Using the D-decomposition method and the principle of the argument, instability intervals are determined for varying stiffness configurations, highlighting the benefits of nontraditional suspension systems in improving local stability.
