Abstract
The present invention relates to a control system of exciter amplitude online continuous adjustment. A hardware system is shown in Figure 1, the control system of double-crank slider excitation mechanism online non-stop amplitude adjustment is studied, and the function of realizing the amplitude online continuous adjustment of an excitation mechanism is designed. According to the double-crank slider excitation mechanism with online non-stop amplitude adjustment, the performance of a mechanical exciter is greatly improved.
Description
Technical field:
The present invention relates to the control system of a kind of vibrator amplitude on-line continuous adjustment, belong to vibration experiment technical field.
Background technology:
Conventional mechanical type vibrator adopts slider-crank mechanism eccentric stiffener, cam mechanism, there is the advantage that equipment is simple, price is low, easy to use, but it is single to there is excited frequency, the problems such as amplitude adjustment difficulty, are difficult to realize ungraded amplitude and multifrequency vibration output; Electromagnetic actuator arbitrarily can control excited frequency, and waveform distortion is little, but will carry out Large travel range test difficulty greatly, and cost is high; Fluid pressure type vibrator is more satisfactory in performance, and low frequency Large travel range easily realizes, but cost is high and utility appliance is large, uses inconvenience.The double crank slider mechanism vibrator developed herein can realize the adjustment of amplitude on-line continuous, has the cost of mechanical type vibrator feature low, easy to use, improves the performance of mechanical type vibrator simultaneously.
Summary of the invention:
The present invention studies the control system that double-crank slide block exciting agency does not shut down amplitude adjustment online, and design achieves the adjustable function of the amplitude on-line continuous of exciting agency.Can not shut down the performance that improve mechanical type vibrator that the double-crank slide block exciting agency that carries out amplitude adjustment is larger online.
Accompanying drawing explanation
Fig. 1: hardware system composition is as figure schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Realize the change of the online non-stop-machine amplitude of double-crank slide block exciting agency; need to select controllable motor to carry out driving crank to rotate; in various controllable motor type; stepper motor has can by Single-chip Controlling rotational frequency; advantages such as operating steadily, speed does not affect by input voltage, price is low, after completing and carrying out mechanics analysis and computing method to mechanism; according to the required torque provided, select 86 stepper motors as drive motor.In order to reach the adjustable requirement of exciting agency amplitude on-line continuous, control system needs to realize the control to phase differential between two crank drive motor, the main control unit of conventional control system mainly contains industrial computer, PLC, 51 single-chip microcomputers, Arduion single-chip microcomputer etc., selects the STC89C52RC51 single-chip microcomputer of cheap, wide application as control module here.
Claims (1)
1. the major function of control program is the on-line continuous adjustable function how realizing vibrator amplitude, in program design, single-chip microcomputer adopts the mode of keys interrupt to work, when entering interruption, the mode of alternately being rotated by a small margin by two stepper motors adjusts two stepper motor phase differential.
