Dynamical stability of mechanism system 機(jī)構(gòu)系統(tǒng)的動(dòng)力學(xué)穩(wěn)定性研究
This paper introduces the wheel mechanism design of in - pipe micro - robot , proposes the dynamical model of restricted in - pipe micro - robot , and analyzes its dynamical stability 提出了管道內(nèi)受限微機(jī)器人的動(dòng)力學(xué)模型,并分析了微型管道機(jī)器人的動(dòng)力學(xué)穩(wěn)定性。
Because cable - stayed bridge has many merits such as long span , light and beautiful structure , well air dynamical stability , single framework style and so on , it becomes the mostly bridge style in bridge construction 斜拉橋由于具有跨越能力大、結(jié)構(gòu)輕巧美觀、受力明確、空氣動(dòng)力穩(wěn)定性好、結(jié)構(gòu)型式簡(jiǎn)潔等優(yōu)點(diǎn),正成為橋梁建設(shè)的最主要的橋型之一。
Taking four spatial truss structures as examples , the structural dynamical stability analyze was carried out applying the stress rate criterion , and the data of the stress rate criterion analysis was compared with those of the displacement criterion analysis 以四種突間桿系結(jié)構(gòu)為例,應(yīng)用應(yīng)力變化率準(zhǔn)則進(jìn)行了結(jié)構(gòu)的動(dòng)力穩(wěn)定分析,并將結(jié)果同位移準(zhǔn)則分析的結(jié)果進(jìn)行了比較。
Four prestressed projects set with two different basis was compared the static force stability , the prestressed project of less internal fore and displacement was obtained . according to this project , three projects of different cable form were given to compare the structural static stability , overall stability and dynamical stability 在此方案的基礎(chǔ)上,確定了三個(gè)不同的布索方案,進(jìn)行靜力、整體穩(wěn)定和動(dòng)力性能比較,得到了布索圈數(shù)對(duì)結(jié)構(gòu)靜力性能、整體穩(wěn)定性能和動(dòng)力性能的影響。
