摘要:
为掌握隧道掘进机电控箱的振动特性，在采掘机械装备国家工程实验室对某型纵轴式掘进机进行了空载、钻进、向右横扫、向下竖扫、向左横扫工况振动特性的试验研究．根据MT/T238.3-2006标准，设计了试验方案及流程，测量了电控箱在各工况的振动数据；获得了电控箱振动时域响应的统计指标，绘制了其振动频域响应的频谱图，并根据ISO2372标准确定了其振动烈度．分析结果表明，电控箱在各工况的振动为非稳态非线性振动，并伴随瞬态冲击；钻进工况振动最剧烈，等级达到C（可容忍）；各工况下的主频带分布较宽，前五阶主振频在10～500 Hz内．为设计开发大功率硬岩掘进机的电控箱隔振系统提供参了第一手参考资料．
Abstract:
To investigate the vibration behavior of the electric control box for efficient isolator design, a heavy-type roadheader is selected to carry out vibration test in NLME under four working conditions: no load, drilling, right/left-ward cutting and down-ward cutting. The experimental scheme and process is designed according to the MT/T238.3-2006 standard, and vibration data of electric control box is logged. The statistical indicators on the time-domain response of electric control box vibration is obtained, the response spectrum of vibration frequency-domain is mapped, and the vibration intensity is determined later according to the ISO2372 standards. The results show that the vibration of electric control box exhibits unsteady and nonlinear features accompanied by transient impact; vibration is up to C level in drilling which is worse than other working conditions; and frequency distributes in broad bandwidth with first five dominant frequencies locating in 10-500Hz. The study can provide essential and valuable references to the new design of high performance electric control box isolator for high-power Hard Rock roadheader .
