Abstract

The invention discloses a device for motion simulation and load measurement of a weapon cabin door. The device comprises a simulation boat body, the weapon cabin door, a U-shaped support frame, a movable balance, a motor and a transmission gear group. The weapon cabin door, the transmission gear group and the motor are respectively installed at a setting position of the U-shaped support frame, a front pivot and a rear pivot of the weapon cabin door are respectively supported by bearings in a first axle base and a second axle base in the U-shaped support frame, an output shaft of the transmission gear group is connected with the rear pivot through a coupler, and an input shaft of the transmission gear group is connected with an output shaft of the motor through a coupler. The U-shaped support frame is fixed on the movable balance, the weapon cabin door, the transmission gear group, the motor, and the U-shaped support and the movable balance are integrated and fixed in the simulation boat body so that the intact cabin door motion simulation and load measuring device is formed. The cabin door can be opened in a serial of fixed angles, and the device can measure instant aerodynamic force in the process that the cabin door is opened/closed with certain speed dynamically, and analytic investigation of cabin door dynamic aerodynamic characteristics is performed.

Description

technical field [0001] The invention relates to a device and method for motion simulation and load measurement of a weapon cabin door, in particular to a device and method for simulating the opening / closing process of an aircraft weapon cabin door and measuring the aerodynamic load acting on the cabin door. Background technique [0002] At present, the aerodynamic load of the hatch door of the weapon compartment is generally realized by changing the angle block. The method similar to the hinge moment measurement method is used to measure the aerodynamic force of the hatch door with a plate strain balance. The disadvantages of this method are: [0003] 1. Low measurement accuracy; [0004] 2. Only a few fixed angles can be used to measure the aerodynamic force; [0005] 3. The consistency between the balance calibration state and the balance experiment state is poor. Contents of the invention [0006] The purpose of the present invention is to provide a weapon cabin door ...
