Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.
[0016] Technical method of the present invention is made up of the following parts:
[0017] Such as figure 1 The shown torsional vibration device is composed of an inertia disk 1, an air bearing 2 and a torsion bar 3, the drive motor 7 is installed on the base 6, the torque sensor 5 is installed on the shaft end of the motor 7, and the coupling 4 is connected to the torsion bar 3 and torque sensor 5. The inertia disc torsion bar device is used to replace the loading motor of the test bench, and the test is started. The drive motor 7 is started according to the speed command to drive the torsional vibration device. Due to the inertia of the inertia disc and the elastic effect of the torsion bar, the torsional vibration device will twist at a certain frequency while rotating. , measure the disturbance torque of the torsional vibration device through...

The invention discloses a method for evaluating the precision of a simulation flexible solar wing driving dynamic simulation test platform. According to the method, a torsion vibration device, the realization of a torsion vibration frequency, the simulation of flexible solar wing driving, and the quantification of the precision are comprised. An inertia plate and a torsion bar are used to simulate the dynamic vibration in the solar wing driving process, through adjusting the mass of the inertia plate and the torsion stiffness of the torsion bar, different torsion vibration frequencies are realized, step velocity driving is applied to simulate a solar wing to rotate toward sun in a directional way, a torque sensor is used to measure a dynamic loading torque as a theoretical value so as to simulate the amplitude and frequency deviations between the torque loaded by the test platform and the theoretical value to quantitatively evaluate the precision of the simulation test platform, the precise evaluation of the simulation flexible solar wing driving dynamic simulation test platform is realized economically and efficiently, and method is economic and easy to operate and has high accuracy.
Description
technical field [0001] The invention relates to the accuracy evaluation of a semi-physical simulation system, in particular to an accuracy evaluation method for simulating a driving dynamics simulation test bench of a flexible solar wing. technical background [0002] The process of simulating the driving dynamics of the flexible solar wing is realized by the semi-physical simulation test bench for the drive mechanism of the sun-orienting device. The semi-physical simulation test-bed for the driving dynamics of the flexible solar wing is a test During the performance test of the drive control performance of the device driven flexible solar wing, problems such as instability of the drive control of the flexible solar wing will be caused by factors such as the performance of the test equipment and loading deviation. make accurate judgments. However, the characteristics of the actual solar panel are very complex, and it is a multi-degree-of-freedom flexible system, and its cha...
