Embodiment two,
As shown in Fig. 4, Fig. 5, Fig. 6, in the present embodiment, mechanical spring type electromagnetic damper 10 comprises four springs 41,42,43,44, the bottom 2 of the seat 1 of the operator's compartment of self-propelled vehicle is divided into four regions 9 of area equation by the first axis 3 and the second axis 4 vertical with the first axis 3, respective one end of four springs 41,42,43,44 is individually fixed in four regions 9, the other end of four springs 41,42,43,44 is individually fixed on the base plate 6 of the operator's compartment of self-propelled vehicle, and the inside of four springs 41,42,43,44 is respectively arranged with magnetic core 12.Four springs 41,42,43,44 are electrically connected with controller 30 respectively, and controller 30 controls the rigidity of four springs respectively by the intensity of current of control four springs 41,42,43,44 according to the electric signal of obliquity sensor 5.
In the present embodiment, obliquity sensor 5 is double-shaft tilt angle sensor, and respective one end of four springs 41,42,43,44 is uniformly distributed in circle that one is the center of circle with the center of the bottom 2 of seat 1 circumferentially,
In the present embodiment, the bottom of seat is divided into four quadrants by the x-axis sounding rod of above-mentioned double-shaft tilt angle sensor and y-axis sounding rod, and respective one end of four springs 41,42,43,44 is individually fixed in four quadrants.In the present embodiment, the straight line at the x-axis sounding rod place of above-mentioned double-shaft tilt angle sensor overlaps with the first axis 3, the straight line at the y-axis sounding rod place of above-mentioned double-shaft tilt angle sensor overlaps with the second axis 4, and therefore above-mentioned four quadrants overlap with four region 9 one_to_one corresponding substantially.
