That is, in order to maintain a feeling of movement, the maximum stroke length of the ride mechanism 1 (the distance between the upper position of the ride mechanism 1 shown in FIG. 1 and the upper position of the ride mechanism 1 shown in FIG. 2) and It is related to the rate of rise and fall.

That is, in order to maintain the descent experienced by the user at the actual bungee jumping, an appropriate washout signal is required for the head mounted display 4, and in order to feel the descent as described above, The mechanism 1 should be lowered to an appropriate gravity acceleration, and the gravity acceleration of the vehicle 1, which gives the feeling that such a user actually bungee jumps, is 0.4 to 0.5G.

In order to maintain the gravitational acceleration of 0.4 to 0.5G when the vehicle 1 is lowered, the maximum stroke of the hydraulic cylinders 8 and 9 should be maintained at least 1 m and the time at least 2 seconds. Therefore, in order to satisfy such a condition, when the vehicle 1 descends with a gravity acceleration of 0.5 G for 3 seconds, the maximum stroke of the vehicle 1 is 2.25 m, and therefore it will descend with a gravity acceleration of 0.5 G. At this time, the descending speed of the ride mechanism 1 is 0.75 m / sec. At this time, the stroke of the piston 10 of the first hydraulic cylinder 8 is 1.5 m and the stroke of the piston 11 of the second hydraulic cylinder 9 is 1 m.

In addition, when the vehicle 1 descends with a gravity acceleration of 0,4G and descends for 4 seconds, the maximum stroke of the vehicle 1 is 3.2m, so the vehicle 1 falls with a gravity acceleration of 0.4G.
