轉動體的負荷
英文
rolling element load-
2. sritable for revolve aport and swing sport when under heavy weight and slow speed, aswell the ccoasion that not form fluid impetus lubrication because of frequently open and closed in the course of loading
2適用於高載低速下的旋轉運動搖擺運動及經常在超負荷下啟閉頻繁而不易形成流體動力潤滑的場合。Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control
與一般的建築空調相比,汽車空調的工作環境惡劣,條件差,控制難度要增加很多,主要體現在以下幾個方面:一是車外熱負荷變化大,難以確定控制參數;二是要求空調負荷大,而且要控制空調使其降溫迅速:三,不便於用電力作為動力源,必須用汽車發動機或輔助發動機來帶動壓縮機,當採用汽車發動機作為動力源時,由於汽車的車速變化大,發動機轉速的變化可從600r min到4000r min ,壓縮機轉速與發動機轉速成正比,其轉速變化高達7倍,給空調系統製冷劑流量控制帶來困難。Abstract : according to the deep analysis of the typical punching process, the loading charts and the amplitude - frequency curves of straight side cnc turret press frame are obtained. in the end the dynamic response of a typical process is calculated using modal superposition method by fem software marc and the static and dynamic stress of some nodes is compared as well
文摘:根據板料沖裁時的工作負荷圖確定了數控回轉頭壓力機的動載荷譜,並通過傅立葉展開,獲得了壓力機的幅頻譜,最後通過marc軟體採用模態疊加法計算了典型沖裁時機身的動態響應,分析了其動態特性,並對特徵點的動靜態應力進行了比較。Rolling element load
