PROBLEM TO BE SOLVED: To suppress the lowering of vibration-proof performance by a simple method, related to a design method of a vibration-proof structure.SOLUTION: A design method of a vibration-proof structure has a construction process (step A10), a setting process (step A20) and a calculation process (step A30). In the construction process (step A10), a model of a receiving-type vibration-proof structure in which an additional system having a second mass body is connected to a main system having a first mass body via an elastic body and an attenuator is constructed. In the setting process (step A20), a phase surplus is set in advance as the phase displacement of an actual vibration phenomenon which is permitted to a designed vibration phenomenon with respect to vibration which is inputted to the main system or the additional system. In the calculation process (step A30), a parameter related to behaviors of the main system and the additional system at the input of the vibration is calculated on the basis of the phase surplus which is set in the setting process.SELECTED DRAWING: Figure 8

    【課題】制振構造の設計方法に関し、簡便な方法で制振性能の低下を抑える。【解決手段】制振構造の設計方法は、構築工程(ステップA10)と設定工程(ステップA20)と演算工程(ステップA30)とを有する。構築工程(ステップA10)では、第一質量体が設けられる主系に対して弾性体および減衰器を介して第二質量体が設けられる付加系を連結した受動型の制振構造のモデルを構築する。設定工程(ステップA20)では、主系または付加系に入力される振動について、設計された振動現象に対して許容される実際の振動現象の位相ずれとして位相余裕を予め設定する。演算工程(ステップA30)では、設定工程で設定された位相余裕に基づいて、振動が入力されたときの主系および付加系の挙動に関するパラメータを演算する。【選択図】図8
