Consider the bogie frame as fixed. Consider the rail plus the elastic deformation at the contact between wheel and rail as an effective spring k. This will be OK only if we are not causing oscillation near a lightly-damped natural frequency of the rail itself. The primary suspension springs are of stiffness k, and are positioned as shown below. Treat the wheels as having mass and a moment of inertia of about a transverse roll or yaw axis through the wheel centroid. Ignore the mass of the axle (we can lump some of it with each wheel as part of m). Treat the axle as rigid. Ignore the fact the wheels are spinning (for now). any b wheel N axle B b wheel humt X Please select the most correct answer below: T = mwy² + (mwa² + 1w)0² 01. 02 3. T = mwy² +10² T = mw(y+a0₂)² + 2(1w+mwa²) 0² + ² mw (ÿ - ab ₂)² Consider the bogie frame as fixed.
