Vehicle-mounted six-degree-of-freedom platform

Abstract

The invention relates to a vehicle-mounted six-degree-of-freedom platform. The vehicle-mounted six-degree-of-freedom platform comprises a base, a vertical vibration layer, a horizontal vibration layer, a pitching layer, a direction adjusting layer and an acceleration sensor, wherein the base is fixedly arranged on a simulated vehicle; the vertical vibration layer is arranged on the base and is used for simulating vibration of the simulated vehicle in the vertical direction; the horizontal vibration layer is arranged on the vertical vibration layer and is used for simulating the vibration of the simulated vehicle in the horizontal direction; the pitching layer is arranged on the horizontal vibration layer and is used for simulating a rotating direction of the simulated vehicle in the horizontal direction; the direction adjusting layer is connected with the pitching layer and is used for simulating a rotating direction of the simulated vehicle in the vertical direction; and the acceleration sensor is fixedly arranged on the base, is in circuit connection with the vertical vibration layer and the horizontal vibration layer, and is used for measuring the vibration of a vehicle body of the simulated vehicle and transmitting driving state direction parameters to the vertical vibration layer and the horizontal vibration layer. The vehicle-mounted six-degree-of-freedom platform has a simple structure, a small size, light weight and low cost; and by stimulating a vehicle driving state, researches on the influences on a vehicle-mounted aircraft positioning system are realized, and the launching precision of the vehicle-mounted aircraft under the vehicle driving state is improved.

Description

technical field [0001] The invention relates to a vehicle-mounted platform, in particular to a vehicle-mounted six-degree-of-freedom platform, which is suitable for simulating the influence of vehicle driving state on a product positioning system. Background technique [0002] When the vehicle-mounted aircraft is launched in the field, in order to ensure the accuracy of the positioning system of the vehicle-mounted product, it is often necessary to stop the aircraft launch vehicle before launching to eliminate the influence of the launch vehicle's own state, such as vehicle horizontal vibration, vertical vibration, and large-radius steering. Impact on positioning system. Therefore, in order to study the influence of the vehicle field driving turntable on the product positioning system, it is necessary to provide a device and equipment capable of simulating the vehicle driving turntable. [0003] At present, the hardware-in-the-loop simulation turntable has been widely used ...
