One-dimensional active following weight reduction hanging device

Abstract

The invention discloses a one-dimensional active following weight-reduction hanging device comprising a one-dimensional active following system and a constant tension control system, wherein a tension sensing assembly comprises two tension sensors used for measuring the tension of a hanging rope coming out from a rope winding assembly, the tension sensors are installed on a tension sensor bracket, and a guide wheel is installed on a guide wheel bracket which is installed on a sensor bracket; and a guide rail slide block is fixedly connected with a mounting bracket, the guide rail slide block is installed on a linear module in a sliding manner, a control motor is installed at one end of the linear module, the control motor is linked with the guide rail slide block, and an angle sensing assembly is installed on the mounting bracket. The one-dimensional active following weight reduction hanging device disclosed by the invention is used for realizing the high precision movement following of a followed element and the ground in the horizontal and vertical directions and providing continuous and stable hanging force in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of weight reduction and suspension, in particular to a one-dimensional active following weight reduction and suspension device. Background technique [0002] If the movement performance test of the mechanism is carried out on the ground to simulate the lunar environment, since the gravity of the ground is 6 times that of the lunar surface, the simulation device must provide a 1 / 6g gravity environment simulation of the lunar surface. Let’s take the deployment of the solar wing sails of the lunar rover as an example. The solar wing sails are installed horizontally above the trolley, and the sides are connected by hinges. During the unfolding process, the center of mass moves along the vertical and horizontal directions. The simulation device must always provide a constant suspension force in the vertical direction of the ground, without generating additional force in the direction of horizontal movement. [0...
