In order to reduce the influence of position error on the generalized force , some related problems about six struts ' coordinated control and its correlative factors were analyzed , thus the control strategy based on single strut position compensation was presented 為了減小或消除平臺(tái)運(yùn)動(dòng)位姿對(duì)力的影響,對(duì)各缸協(xié)同力控制及其影響因素等相關(guān)問(wèn)題進(jìn)行了分析,提出基于單缸位置補(bǔ)償?shù)牧刂撇呗浴?
Based on the analytical model of the generalized force spectra of the first mode of typical lattice towers in along - wind direction , simplified empirical formulae to evaluate along - wind dynamic responses of lattice towers under wind load are proposed in this paper 摘要基于格構(gòu)式塔架順風(fēng)向一階廣義荷載譜解析模型,提出了格構(gòu)式塔架順風(fēng)向風(fēng)振響應(yīng)簡(jiǎn)化計(jì)算公式,這些簡(jiǎn)化公式將求格構(gòu)式塔架順風(fēng)向風(fēng)振響應(yīng)的復(fù)雜積分變?yōu)楹?jiǎn)便的代數(shù)運(yùn)算。
Thirdly , based on the geometrical differential constraints and force balancing constraints of the coordinated flexible manipulators , the mutual relationships between the kinematic and dynamic parameters in static configuration have been presented . the manipulation stiffness of the coordinated system has also been proposed . the manipulability of the flexible robot system has been then analyzed in two aspects : i ) the global characteristics in the manipulation workspace based on the manipulation stiffness ; ii ) the local property of the reachable boundary of generalized forces 然后,利用柔性機(jī)器人協(xié)調(diào)抓取的幾何微分約束和力平衡約束,通過(guò)深入分析系統(tǒng)在靜態(tài)位形時(shí)其內(nèi)部各運(yùn)動(dòng)參量和力參量之間的關(guān)系,定義了系統(tǒng)的操作剛度,從兩個(gè)方面對(duì)系統(tǒng)的操作性能進(jìn)行了分析: 1 )操作空間中,基os于系統(tǒng)操作剛度的全局特性; 2 )在一定約束的條件下,系統(tǒng)操作力矢端可達(dá)二邊界的局部特性。
