Description

一种飞行模拟系统及其抖振平台A flight simulation system and its buffeting platform

技术领域technical field

本发明涉及飞行器模拟技术领域,具体涉及一种用于飞行模拟系统的抖振平台。本发明还涉及一种包括该抖振平台的飞行模拟系统。The invention relates to the technical field of aircraft simulation, in particular to a chattering platform used for a flight simulation system. The invention also relates to a flight simulation system comprising the buffeting platform.

背景技术Background technique

飞行模拟系统是模仿航空器的飞行状态、飞行环境和飞行条件,并给驾驶员提供视觉、听觉、触觉和运动感觉的状态仿真装置。抖振平台是直升机飞行模拟系统的重要组成部分,其能够模拟直升机在螺旋桨高速旋转时与气流相互作用而产生的高频抖动,使直升机飞行模拟系统更加贴近要模拟的直升机抖动的真实情况,从而提高模拟系统的仿真能力。The flight simulation system is a state simulation device that simulates the flight state, flight environment and flight conditions of the aircraft, and provides the pilot with visual, auditory, tactile and kinematic sensations. The buffeting platform is an important part of the helicopter flight simulation system. It can simulate the high-frequency vibration generated by the interaction between the helicopter and the airflow when the propeller rotates at high speed, so that the helicopter flight simulation system is closer to the real situation of the helicopter vibration to be simulated, thereby Improve the simulation capability of the simulation system.

请参考图1-图3,图1为现有技术中抖振平台的结构示意图;图2为图1所示抖振平台中电机组件的结构示意图;图3为图2中电机组件的侧视图。Please refer to Fig. 1-Fig. 3, Fig. 1 is the structural diagram of the buffeting platform in the prior art; Fig. 2 is the structural diagram of the motor assembly in the chattering platform shown in Fig. 1; Fig. 3 is the side view of the motor assembly in Fig. 2 .

在现有技术中,用于飞行模拟系统的抖振平台通常采用振动电机的形式。抖振平台包括设置于底部的支架、通过减震机构支撑于支架上方的台面和安装在台面下方的振动电机;其中,台面由振动电机带动进行上下振动,减震机构可以为橡胶弹簧、复合弹簧、充气弹簧等。在工作过程中,电机的旋转轴带动偏心块进行旋转,在旋转的过程中偏心块产生沿偏心块重心到旋转轴中心的离心力,从而推动与之固定连接的台面上下运动。根据离心力方程:f=mv2/r,其中f为离心力,m为偏心块的质量,v为偏心块重心的线速度,r为偏心块重心的半径。可见电机旋转的速度越快则离心力越大,平台的振幅越大。In the prior art, buffeting platforms used in flight simulation systems usually take the form of vibration motors. The chattering platform includes a bracket set at the bottom, a table top supported above the bracket by a shock-absorbing mechanism, and a vibration motor installed below the table; wherein, the table is driven by the vibration motor to vibrate up and down, and the shock-absorbing mechanism can be a rubber spring, a composite spring , Inflatable springs, etc. During the working process, the rotating shaft of the motor drives the eccentric block to rotate. During the rotation, the eccentric block generates a centrifugal force along the center of gravity of the eccentric block to the center of the rotating shaft, thereby pushing the table fixedly connected with it to move up and down. According to the centrifugal force equation: f=mv2/r, where f is the centrifugal force, m is the mass of the eccentric block, v is the linear velocity of the center of gravity of the eccentric block, and r is the radius of the center of gravity of the eccentric block. It can be seen that the faster the motor rotates, the greater the centrifugal force and the greater the amplitude of the platform.

但是,现有的抖振平台,只能够通过调整电机的转速来调节振动的频率,但是无法调节振幅,频率和振幅是一个恒定的关系,从而只能模拟直升机在某一阶段的振动效果,振动模拟的仿真性能较差。因此,提供一种新型的抖振平台,以期能够同步调节抖动振幅和频率,从而扩大模拟范围,提高仿真性能,就成为本领域技术人员亟待解决的问题。However, the existing buffeting platform can only adjust the frequency of vibration by adjusting the speed of the motor, but cannot adjust the amplitude. The frequency and amplitude are a constant relationship, so it can only simulate the vibration effect of the helicopter at a certain stage. The simulation performance of the simulation is poor. Therefore, it becomes an urgent problem to be solved by those skilled in the art to provide a new type of chattering platform in order to simultaneously adjust the shaking amplitude and frequency, thereby expanding the simulation range and improving the simulation performance.

本发明所提供的抖振平台用于飞行模拟系统,该抖振平台包括支撑座舱的上平台、通过支腿组件支撑所述上平台的下平台,以及安装于两平台之间的振动机构和振幅调整机构;其中,所述振动机构包括电机、与所述电机的输出轴传动连接的偏心轮,和与所述偏心轮相固接的传动杆组;所述传动杆组包括导向杆和振动杆,所述振动杆的顶端抵靠于所述上平台;所述振幅调整机构包括伸缩缸、与所述伸缩缸的缸杆固接的滑块,和开设于所述下平台上的导轨;所述滑块与所述导向杆可滑动连接,所述振动杆与所述滑块固定连接。The buffeting platform provided by the present invention is used in a flight simulation system.

在一种具体实施方式中,本发明所提供的抖振平台用于飞行模拟系统,该抖振平台包括支撑座舱的上平台1、通过支腿组件2支撑所述上平台1的下平台3,以及安装于两平台之间的振动机构和振幅调整机构;其中,所述振动机构包括电机41、与所述电机41的输出轴传动连接的偏心轮42,和与所述偏心轮42相固接的传动杆组;所述传动杆组包括导向杆43和振动杆44,所述振动杆44的顶端抵靠于所述上平台1;所述振幅调整机构包括伸缩缸51、与所述伸缩缸51的缸杆固接的滑块52,和开设于所述下平台3的支撑板54上的导轨53;所述滑块52与所述导向杆43可滑动连接,所述振动杆44与所述滑块52固定连接;所述滑块52可在导轨53上滑动。该电机41具体为伺服电机41。In a specific embodiment, the buffeting platform provided by the present invention is used in a flight simulation system, and the buffeting platform includes an upper platform 1 supporting the cockpit, a lower platform 3 supporting the upper platform 1 through outrigger assemblies 2, And a vibration mechanism and an amplitude adjustment mechanism installed between the two platforms; wherein, the vibration mechanism includes a motor 41, an eccentric wheel 42 connected to the output shaft of the motor 41, and a fixed connection with the eccentric wheel 42 The transmission rod group; the transmission rod group includes a guide rod 43 and a vibration rod 44, and the top end of the vibration rod 44 is against the upper platform 1; the amplitude adjustment mechanism includes a telescopic cylinder 51, and the telescopic cylinder The slider 52 fixed to the cylinder rod of 51, and the guide rail 53 provided on the support plate 54 of the lower platform 3; the slider 52 is slidably connected with the guide rod 43, and the vibrating rod 44 is connected with the The slider 52 is fixedly connected; the slider 52 can slide on the guide rail 53 . The motor 41 is specifically a servo motor 41 .

上述上平台1和/或下平台3可以为框架式结构或板式结构,由于框架式结构便于节约材料,优选采用框架式结构。当下平台3为框架式结构时,其中轴线上安装有支撑梁,所述振动机构和所述振幅调整机构均安装于所述支撑梁上,以便于机构布置。The above-mentioned upper platform 1 and/or lower platform 3 can be a frame structure or a plate structure. Since the frame structure is convenient for material saving, the frame structure is preferred. When the lower platform 3 is a frame structure, a support beam is installed on the central axis, and the vibration mechanism and the amplitude adjustment mechanism are both installed on the support beam, so as to facilitate mechanism arrangement.

在工作过程中,电机41的输出转动通过支撑轴承和同步带轮等结构传递给偏心轮42,偏心轮42随之转动而产生上下方向的线性位移,再通过传动杆组将振动经上平台1传递给上方座舱,从而实现振动模拟。当需要调整振动幅度时,调节伸缩缸51的伸出行程,从而带动滑块52在导轨和导向杆43上滑动,即可调整振动杆44相对于上平台1的位置,振动杆44支撑点位置不同则其传递给上平台1的振幅也不同,从而实现抖振平台的振幅调节。上位机通过控制器、驱动器控制驱动系统,驱动系统控制抖振平台频率大小,电机41转速越大振动频率越高,振幅调节系统控制抖振平台的振动幅值大小,伸缩缸51的伸出量越大振动的幅值越大。这样,该抖振平台通过电机41转速调整振动频率,并同时通过伸缩缸51的伸缩幅度调整振动杆44的施力位置,通过调整力矩的大小调节振幅,从而实现了抖动振幅和频率的同步调节,进而扩大了模拟范围,提高了仿真性能。During the working process, the output rotation of the motor 41 is transmitted to the eccentric wheel 42 through structures such as supporting bearings and synchronous pulleys, and the eccentric wheel 42 rotates accordingly to produce a linear displacement in the up and down direction, and then the vibration is transmitted through the upper platform 1 through the transmission rod group. Passed to the cockpit above to achieve vibration simulation. When it is necessary to adjust the vibration amplitude, adjust the extension stroke of the telescopic cylinder 51, thereby driving the slider 52 to slide on the guide rail and the guide rod 43, and then adjust the position of the vibration rod 44 relative to the upper platform 1, and the position of the support point of the vibration rod 44 If they are different, the amplitudes transmitted to the upper platform 1 are also different, so as to realize the amplitude adjustment of the chattering platform. The upper computer controls the drive system through the controller and the driver. The drive system controls the frequency of the chattering platform. The higher the rotation speed of the motor 41, the higher the vibration frequency. The amplitude adjustment system controls the vibration amplitude of the chattering platform and the extension of the telescopic cylinder 51 The larger the vibration, the greater the amplitude. In this way, the vibrating platform adjusts the vibration frequency through the rotation speed of the motor 41, and at the same time adjusts the force application position of the vibrating rod 44 through the expansion and contraction range of the telescopic cylinder 51, and adjusts the vibration amplitude by adjusting the size of the torque, thereby realizing the synchronous adjustment of vibration amplitude and frequency , thus expanding the simulation range and improving the simulation performance.

为了提高与上方座舱的连接可靠性和稳定性,保证平台支撑能力,上述上平台1和下平台3可以均为矩形平台,此时支腿组件2为四组,各所述支腿组件2分设于所述矩形平台的四角,以提供较好的支撑,保证稳定性。显然地,支腿组件2也可以设置六组或更多组。支腿组件2分布在抖振平台的四角,承担整个平台的负载,分别与上平台1和下平台3的支撑体固定。In order to improve the reliability and stability of the connection with the upper cockpit and ensure the support capacity of the platform, the above-mentioned upper platform 1 and the lower platform 3 can be both rectangular platforms. At this time, there are four sets of outrigger assemblies 2, and each of the outrigger assemblies 2 is set separately. on the four corners of the rectangular platform to provide better support and ensure stability. Apparently, six or more groups of outrigger assemblies 2 can also be provided. The outrigger assembly 2 is distributed at the four corners of the buffeting platform, bears the load of the entire platform, and is respectively fixed to the supports of the upper platform 1 and the lower platform 3 .

所述支腿组件2包括支腿本体21和弹簧缓冲结构22,所述弹簧缓冲结构22设置于所述支腿本体21与所述上平台1之间,通过设置弹簧缓冲结构22降低颠簸,并通过支腿本体21提供支撑力,保证支撑稳定性。The outrigger assembly 2 includes a outrigger body 21 and a spring buffer structure 22, the spring buffer structure 22 is arranged between the outrigger body 21 and the upper platform 1, and the bump is reduced by setting the spring buffer structure 22, and The supporting force is provided by the leg body 21 to ensure the supporting stability.
