摘要
针对当前航空航天、电子工业等领域内中小型高精度振动台的工程需求日益增加,提出了一种基于计算机技术、嵌入式控制技术和电机控制技术的整套振动台设计方案。为了验证所设计的机械式振动台的波形复现是否满足振动台测试精度要求,以真实的地震加速度信号作为振动台的激励输入,对振动台关键模块进行性能测试试验,同时比较振动台在空载和负载两种不同工况状态下的波形复现精度。结果表明:各个模块的性能满足系统需要,在不同工况下的波形复现最大误差控制在0.15mm〜0.28mm范围之内,波形跟随性良好,整个振动台系统架构设计合理,系统稳定可靠。该方案可为未来中小型振动台的设计和工程应用提供技术支持,具有一定工程实际应用意义和参考价值。
Aiming at the increasing engineering requirements of small and medium-sized high-precision shaking table in the current aerospace,electronics industry and other fields,a complete design scheme of shaking table based on computer technology,embedded control technology and motor control technology is proposed.In order to verify whether the waveform replication of the designed shaking table meets the test accuracy requirements of the shaking table,the real seismic acceleration signal is set as the excitation input of the shaking table,and the performance test of the key modules of the shaking table is carried out.In addition,the waveform replication accuracies of the shaking table under two different working conditions of no load and load are compared.The results show that the performance of each module meets the needs of the system,the maximum error of the waveform replication under different working conditions is controlled within the range of 0.15〜0.28 mm,and the waveform follows well.The whole shaking table system is designed rationally and the system is stable and reliable.This scheme can provide technical support for the design and engineering application of small and medium-sized shaking table in the future,and has certain practical engineering application significance and reference value.
