PROBLEM TO BE SOLVED: To provide a suspension structure which makes compatible both quietness and steering operability related to a suspension vibration analysis device and a vibration analysis program.SOLUTION: A storage part 21 for storing a rigid body model in which a plurality of rigid bodies are bush-connected to one another as a model of a suspension is arranged in a vibration analysis device which analyses vibration inputted to a vehicle body from a road face via the suspension. A calculation part 22 is also arranged which calculates the input power of the vibration inputted to the vehicle body on the basis of an equation of motion which is regulated in a relationship between and among the rigidity of the rigid body model, displacement and an external force. Furthermore, an estimation part 24 is arranged which estimates a change position in which the input power is reduced on a connecting point between a plurality of the rigid bodies.SELECTED DRAWING: Figure 3 |
