Abstract

The invention discloses a vehicle driving simulator with heavy-load wideband response. A simulation cabin is arranged on a moving platform of a six-freedom-degree hydraulic driving moving platform and a three-freedom-degree electric-driving moving seat positioned in the simulation cabin. The vehicle driving simulator comprises a seat, a seat moving platform, and three sets of seat driving mechanisms for connecting a connecting seat moving platform and the moving platform and with the same structures; three lower hinges are respectively and uniformly arranged on the moving platform; three upper ball hinges are respectively connected with the lower hinges by an electric cylinder and a speed reducer; a motor is connected with an input shaft of the speed reducer; and the upper ball hinges areuniformly fixed under the seat moving platform simultaneously. In the vehicle driving simulator, the moving platform provides motion for the vehicle driving simulator under the heavy-load condition, the three-freedom-degree electric-driving moving seat provides high-frequency wideband motion of the seat, a driver feels the combined motion after the two motions are superimposed, the defect that the traditional vehicle driving simulator can only work under low-frequency band when in heavy-load motion is avoided and the sense of reality for vehicle driving is improved.

Description

technical field [0001] The invention relates to a vehicle driving simulator, in particular to a vehicle driving simulator with heavy-duty broadband response. Background technique [0002] The vehicle driving simulator is a simulation system that can correctly simulate the actions of driving and manipulating the vehicle and obtain the driving feeling of the real vehicle. The vehicle driving simulator integrates various advanced technologies such as sensor technology, computer technology, 3D real-time animation technology, and network technology. With the help of vehicle driving simulators, the "driver-car-road" interrelationship can be studied and drivers can be trained. The characteristics of the vehicle driving simulator determine that it has the following advantages: 1) good safety; 2) good reproducibility; 3) high economy; 4) conducive to the development of related equipment. Therefore, vehicle driving simulators are often used to replace real equipment to train operato...
