Sintered ndfeb has excellent magnetic properties with low price while the strength and toughness are poor which result in poor machinability, and it is easy to be broken. so they can not be used in areas with impact
但是,這種材料強度和韌性差,機械加工困難,應用過程中容易掉角開裂,特別是在一些有沖擊振動載荷的領域應用受到限制。During aircraft take - off and landing phases, the dynamic loads and vibrations caused by landing impact and the unevenness of runway will result in airframe fatigue, discomfort of passenger and the reduction of the pilot ' s ability to control the aircraft
在飛機起飛和著陸過程中,由著陸沖擊和跑道不平引起的沖擊載荷和振動,會造成飛機機體疲勞損傷、乘客不適及地面駕駛操縱能力的降低。因此,在設計飛機起落架緩沖器時,必須限制起落架傳遞給飛機的沖擊載荷。The new drive system adopts gear drive instead of the traditional rubber belt transmission, therefore realizes optimum transmission of pumping unit by overcoming the disadvantages of the belt transmission
該系統把傳統的抽油機膠帶傳動改變為齒輪硬性傳動,徹底克服了因膠帶傳動而造成的抽油機傳動效率低、電動機過載被燒毀,以及因慣性載荷造成抽油機的沖擊和振動等弊端,實現了傳動最優化。The landing impact has been recognized as a significant factor in structural fatigue damage, dynamic stress on the aircraft airframe, and crew and passenger discomfort
而這種沖擊載荷被認為是造成飛機及其起落架結構發生疲勞與振動破壞、引起乘員不舒適的重要因素。The effect that brunt load act on the arm frame of the bump auto is discussed by way of dynamic response analysis
通過動態響應分析,討論了工作沖擊載荷對泵車臂架振動的影響。A model experiment is made on an actual floating slab track, and the vibration transfer property of this track under three different frequencies of impact load is mainly tested
對浮置板進行了1 : 1模型試驗,主要測試了浮置板在3種不同頻率沖擊載荷作用下的振動傳遞特性。On the other hand, heavy tamping is also a transient impact load that will produce strong ground vibration
同時,從加載角度考慮,強夯又是一種瞬時沖擊荷載,作用在地面時產生振動問題。En iso 13753 mechanical vibration and shock. hand - arm vibration. method for measuring the vibration transmissibility of resilient materials when loaded by the hand - arm system
機械振動和沖擊.手-臂振動.手-臂體系荷載時彈性材料振動可傳遞性測量方法Nevertheless, the widely existed overconstraints in the mechanisms will make the quality of the mechanisms very sensitive to the inevitable manufacturing, assembly errors ( especially, the errors resulted from the shape and position between kinematic pair elements and their axes ). at the same time, because the internal and external uncertain factors such as non - plane characteristic of dynamic parameters of links ( such as mass distribution, inertia forces, etc. ), bending and twist of links, and the changes of environment and operating condition are inevitable, they will form the disturbance to planar constraints and make them possess the characteristic of " uncertain "
但是,平面連桿機構中廣泛存在的過約束,造成機構對製造、安裝誤差特別是運動副元素的形位誤差十分敏感;同時,由於不可避免的內部和外部不確定因素的影響,常常會造成機構運動的「障礙」及系統中某些構件的變形和運動副中的附加動載荷,引起機械的振動、沖擊、噪聲等而導致機械的效率和工作性能的降低。Meanwhile, there is a kind of constraint, only the frequency constraint. the optimization design is computed to increase the first mode frequency. as the results, the first mode frequency is increased and the amplitude of the arm frame is cut down
選擇比值較大的結構參數為設計變量,以一階頻率為性能約束,進行了旨在提高一階固有頻率的優化設計,提高了泵車的一階固有頻率,使一階固有頻率盡可能高於油缸沖擊載荷的頻率,從而減小泵車臂架系統的振動幅度。The response that the arm frame is affected by different brunt load is observed through changing the peak of brunt load. so lowing the dynamic load ' s peak is a mean to solve the problem that vibration is too big
通過改變油缸沖擊作用的峰值,觀察臂架機構在不同油缸沖擊載荷作用下的響應,可知減小泵車油缸沖擊峰值也是減小臂架振動的有效途徑之一。分享友人
