Description
Technical field
The present invention relates to the design of shock attenuation device structure, relate in particular to a kind of vibration simulator for high-speed maglev train suspended sensor vibration-testing.
Background technology
Magnetic-levitation train is divided at a high speed, two kinds of large classes of low speed, comprise at a high speed German TR series, Japanese MLX series etc., low-speed maglev train comprises Japanese HSST series, and domestic low-speed maglev train comprises the various sample car of being developed respectively by units such as Southwest Jiaotong University, the National University of Defense technology, Shanghai Maglev centers.Magnetic suspension train can deorbit, and critical component is suspension rack, and it plays a part to form a connecting link as running part, is not only bearing the above weight of empty spring, and is the carrier of stable suspersion, traction.Therefore determining the stability of magnetic-levitation train motion for the control of suspension rack.
The suspension of magnetic-levitation train is controlled and is mainly consisted of suspension controller and suspended sensor, suspended sensor is for testing the levitation gap of train with respect to track, and signal is inputted to the processor in suspending chopper, the method that it is added in the effective voltage at levitating electromagnet two ends according to the input signal of input pickup by change changes the electric current of levitating electromagnet, thereby regulate the attractive force of levitating electromagnet to the steel guide rail, make the train stable suspersion.Suspended sensor is an important step of magnetic suspending train control system as can be seen here, and it directly affects the suspension effect of train.Suspended sensor is installed on the suspension rack place in magnetic-levitation train, the vibration of crossing seam or the suspension rack that causes of other reason due to track irregularity, train can pass to suspended sensor, therefore must Elastic Vibration in the design of suspended sensor on the impact of sensor output signal and the reliability of sensor self, with precision and the degree of stability of guaranteeing the suspended sensor output signal.
In the research and manufacture process of current suspended sensor, emphasis is to consider noise reduction and the stability requirement of suspended sensor output signal in complex electromagnetic environment, and the vibration of often having ignored the suspended sensor that the vibration by suspension rack causes is to the reliability of sensor self electron device with to the interference of output signal; Testing apparatus for suspended sensor is also the linearity of the sensor output gap width under the tested static environment.And the distortion of the sensor signal caused due to vibration and the inefficacy of sensor have occurred in the magnetic-levitation train operational process, therefore be necessary the vibration environment in suspended sensor work is simulated, and the reliability of testing sensor under vibration condition and the stability of signal output.Due to particular job state of magnetic-levitation train and the polytrope of experiment condition, harmony and the adjustability of the dither of analog machine had to quite high requirement.
The present invention proposes a kind of high-speed maglev train suspended sensor vibration-testing analogue means, by vibrating motor is set in device, and the frequency and the exciting force that by the rotational speed regulation of regulating vibrating motor, vibrate, meticulous damping is set between sensor installation seat and base, reaches the purpose of the vibrations operating mode of good analog sensor simultaneously.
Summary of the invention
In view of the above deficiency of prior art, of the present inventionly provide a kind of high-speed maglev train suspended sensor vibration-testing analogue means, make it the adjustable cooperation by vibrating motor and damping, reach the effect of the vibrations operating mode of good analog sensor.
