Embodiment

[0050] The motor 17 rotates clockwise at a constant speed at a speed of 2 rev / s, then the large bevel gear 26 with a semi-through hole and the large bevel gear 22 with a through hole rotate oppositely at the same speed. After the sense controller 28 determines the size of the theoretical force sense, the magneto-rheological fluid controller 31 determines the theoretical current of the excitation coil 10, and at the same time, the force sense controller 28 determines that the direction of the theoretical force sense should be clockwise. The magneto-rheological fluid controller 31 controls the current generator 32, selects the magneto-rheological fluid between the large bevel gear 26 and the output end cover plate 8, and electrifies the corresponding external excitation coil 10 to excite the magneto-rheological fluid. The magnetorheological fluid inside the coil 10 generates a magnetic field to change the viscosity of the magnetorheological fluid to an appropriate size. Under the...

Abstract

The invention discloses a single-cylinder bevel gear type magneto-rheological fluid force sense feedback device and an application method thereof. The single-cylinder bevel gear type magneto-rheological fluid force sense feedback device comprises a force sense simulation system, a force sense control system, a force sense generation system, a reversing system and a power supply system. The single-cylinder bevel gear type magneto-rheological fluid force sense feedback device and the application method thereof have the advantages that a bevel gear reversing device is adopted, so that the devicehas light total weight, reduce the manufacturing cost, is molded easily and is assembled easily, thereby solving the problems that the structure of the device is complicated, the vibration noise is large, and the cost is high.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic control and intelligence, and relates to a single-tube bevel gear type magneto-rheological fluid force feedback device and a use method thereof. Background technique [0002] Traditional vehicle road tests have disadvantages such as high cost, long time, limited site conditions, and accidents in extreme conditions. It is the current mainstream trend to replace traditional vehicle road tests with vehicle driving simulation systems. A mature driving simulation system can truly reflect the vehicle's motion state, road conditions, surrounding environment, and various body and force sensations, which greatly reduces the capital cost, time cost and labor cost of the vehicle road test. Among them, accurate steering wheel force feedback is essential, which to a large extent determines whether the driver can make corresponding operations according to a given route or driving intention, and is...
