Abstract

A horizontal type three-axis simulation turntable with four symmetrical pitch axis motors comprises an O-shaped frame, the two ends of the O-shaped frame are connected with pitch mechanisms, the pitch mechanisms are fixedly installed on a base, each pitch mechanism comprises a support fixed to the base, main shafts are installed in the supports through bearing assemblies, outer motor stators are fixed to the outer sides of the supports, outer motor rotors are installed on the inner sides of the outer motor stators, the outer motor rotors are fixedly connected with the main shafts through outer motor rotor bases, inner motor stators are fixed on the inner sides of the supports, inner motor rotors are installed on the inner sides of the inner motor stators, the inner motor stators are fixedly connected with the main shafts through inner motor rotor bases, frame holes are formed in the two ends of the O-shaped frame, and expansion sleeves arranged on the main shafts in a sleeving mode are arranged in the frame holes. Motors of the two pitch mechanisms are symmetrically arranged, the space between the main shafts and the O-shaped frame is reasonably utilized, meanwhile, torque is input to the two ends of the main shafts, and the torsional rigidity and the frequency response characteristic of the main shafts are improved to the maximum extent.

Description

technical field [0001] The invention relates to a horizontal simulation turntable, in particular to a horizontal three-axis simulation turntable with four symmetrical pitch axes and four motors. Background technique [0002] As a platform for test verification, the three-axis electric turntable plays an important role in the development of missiles and aerospace vehicles. The missile guidance system is the core component of the missile and the aircraft. There are two main test methods for evaluating the performance of the guidance system: one is to obtain data during actual shooting or actual flight, and to find problems from it and continuously improve it; The simulation test equipment tests and evaluates various performance indicators of the guidance system on the ground. Since the dynamic characteristics of the missile (or aircraft) seeker are truly simulated under laboratory conditions, this kind of equipment has been more and more widely used, and it is suitable for hi...

Problems solved by technology

[0007] The pitch axis system of the three-axis horizontal simulation turntable is the outermost axis system, and the moment of inertia of this axis system is also the largest. With the continuous improvement of the frequency response index in recent years, the previous shaft system design method is difficult to meet the requirements. In some applications, in order to meet greater frequency response requirements, it is necessary to increase the radial and axial dimensions of the motor. When the size reaches φ1000mm or more, it will bring a lot of inconvenience to the manufacture of the motor and the assembly of the turntable. Therefore, it is necessary to pass Increase the number of motors to meet the requirements of certain application scenarios
