Worm gear pair-based simulator platform capable of infinitely rotating around Z axis

Abstract

The invention discloses a worm gear pair-based simulator platform capable of infinitely rotating around a Z axis. A worm gear and a ring rail are coaxially fixed on the upper end of a static platform base in turn; the lower ends of sliding blocks in six sets of moving parts are connected with the ring rail in a sliding mode respectively; the upper end of the sliding block in each set of the moving parts is connected with a sliding block fixing plate; a servo motor is arranged on a first fixing plate on one side of the sliding block fixing plate through a speed reducer; an output shaft of the speed reducer is connected with a worm, and the worm is meshed with the worm gear; four corners on the lower side of the sliding block fixing plate are respectively provided with a pulley wheel which is jointed with convex edges of the inner and outer side surfaces of the ring rail; and a control wire arranged on a control box in the static platform base is connected with six servo motors respectively. The simulator platform infinitely rotates around the Z axis to avoid a leaching-out filtering algorithm in the rotation direction around the Z axis, so that the validity of simulation is effectively improved, the length of travel in X, Y, and Z direction in particular the Z direction is effectively improved, and the working space of the simulator is greatly increased.

Description

technical field [0001] The invention relates to a driving simulator platform, in particular to a worm gear pair-based simulator platform capable of infinite rotation around a Z axis. Background technique [0002] The driving simulator is a mechanical device that simulates the driving experience. It simulates the feeling in the real equipment as much as possible (such as vehicle vibration, uphill and downhill, turning, etc.), and is used to train the driver indoors. The driver will not be affected by the simulated driving. injured in the accident. The characteristics of the driving simulator determine that it has the following advantages: 1) Good safety, using the driving simulator can safely carry out high-speed, extreme driving and very dangerous safety experiments, which can greatly improve the safety of training; 2) Reproducibility Due to the fact that factors such as vehicle state and experimental conditions are difficult to control, the reproducibility of the real vehi...

Problems solved by technology

[0011] Aiming at the shortcomings that various washing-out filtering algorithms cannot eliminate the difference between the real feeling and the driving simulator's motion sensation, especially the inability to continuously rotate around the Z-axis direction, the present invention provides a worm gear pair-based worm gear pair that can infinitely rotate around the Z-axis Rotating Simulator Platform
