To provide a force calculation device capable of obtaining prying force generated in a bush.SOLUTION: A force calculation device 1 calculates force received by a bush 10 provided between a bolt 32 fixed to a body 30 of a vehicle and a suspension arm 40. The bush 10 includes an inner cylinder 11 and a rubber cylinder 12. The force calculation device 1 comprises: a first stress sensor 13a buried in the inner cylinder 11 and detecting first stress which is stress generated in the rubber cylinder 12; a second stress sensor 13b buried in the inner cylinder 11 so as to be located on the same side with the first stress sensor 13a with respect to a central axis line L of the bolt 32 on the flat surface including the central axis line L and detecting second stress which is stress generated in the rubber cylinder 12; and a prying force calculation unit 21 for calculating prying force generated in the rubber cylinder 12 on the basis of a first position where the first stress sensor 13a is positioned, a second position where the second stress sensor 13b is positioned, the first stress and the second stress.SELECTED DRAWING: Figure 2

    【課題】ブッシュに生じたこじり力を取得することができる力算出装置を提供する。【解決手段】力算出装置1は、車両のボデー30に対して固定されたボルト32とサスペンションアーム40との間に設けられたブッシュ10が受ける力を算出する。ブッシュ10は、内筒11と、ゴム筒12と、を有する。力算出装置1は、内筒11に埋設され、ゴム筒12に生じる応力である第1応力を検出する第1応力センサ13aと、ボルト32の中心軸線Lを含む平面上において中心軸線Lに対して第1応力センサ13aと同一側に位置するように内筒11に埋設され、ゴム筒12に生じる応力である第2応力を検出する第2応力センサ13bと、第1応力センサ13aの位置である第1位置、第2応力センサ13bの位置である第2位置、第1応力、及び第2応力に基づいて、ゴム筒12に生じたこじり力を算出するこじり力算出部21と、を備える。【選択図】図2
