鋼軌波磨的分析儀–RCA
RCA是鐵路系統(tǒng)上實(shí)用的儀器設(shè)備。
railmeasurement的RCA一開始不規(guī)范,是鋼軌波磨這部分,對車輛來說,RCA初被設(shè)計(jì)用于在3-15km/h列車上,RCA近版本已工作過0.5km/h速度范圍內(nèi)的典型速度磨削火車(在軋機(jī))~50km/h(在高軌道車輛,這些設(shè)備是用來幫助磨軌)。設(shè)備在設(shè)計(jì)時(shí)考慮到用戶,提供簡潔的信息,相關(guān)設(shè)計(jì)重組。
RCA已應(yīng)用于以下領(lǐng)域:
鐵路重組
波紋的調(diào)查
測量違規(guī)行為,是與地面噪聲和振動有關(guān)的違規(guī)行為
這里也考慮了設(shè)備的驗(yàn)證。
Gauge-adjustable RAC是一個(gè)很小的裝在鐵路磨床上的
RCA提供用于高軌道車輛幫助開發(fā)一個(gè)混合交通鐵路系統(tǒng)磨削方案的一個(gè)的例子。該系統(tǒng)設(shè)計(jì)用于在50公里/小時(shí)速度的列車上,RCA關(guān)鍵部件運(yùn)行維護(hù)量,30000km后才需要維護(hù)。
RCA已成功地應(yīng)用于地鐵磨床十多年,保養(yǎng)成本很低。
