negative rigidity 中文意思是什麼
negative rigidity
解釋
負剛度-
Those sensitive parameters making system have negative damping and occur self - excited shimmy are horizontal pulling lever rigidity, tire sideslip rigidity, steering gear rigidity and damping, kingpin equivalent damping, kingpin caster angle, tire drag. and wheel center distance, tire side rigidity, vehicle wheel unbalanced mass, tire vertical rigidity, and distance from kingpin center to the vertical central line plane of tire have great influence on shimmy, but they do n ' t make the system have negative damping. and horizontal pulling lever damping, suspension damping and rigidity have very small influence on shimmy
橫拉桿剛度、輪胎的側偏剛度、轉向機剛度、轉向機阻尼、繞主銷當量阻尼、主銷后傾角、輪胎拖距是影響擺振的敏感性參數，適當調節某一參數可引起系統的負阻尼，使系統產生自激擺振；輪距、輪胎側向剛度、車輪上的不平衡質量、輪胎垂向剛度及主銷延長線與地面交點至車輪平面的距離對擺振的影響也較大，但不會使系統出現負阻尼；而橫拉桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。 -
The elastic methods are beam - columns method, the pseudo load method, the pseudo lateral load method, the iterative gravity load method and the negative rigidity method
常用彈性分析的方法有：樑柱法、虛擬荷載法、虛擬側向荷載法、迭代重力荷載法和負剛度法。 -
Moreover, it showed that the linearity rising relations were existed between the laser power and the thickness of hardening layer, and the linearity negative rising relations between the scanning velocity and peak rigidity
此外，結果還表明激光功率與淬硬層厚度成線性增長，而掃描速度與峰值硬度成線性負增長關系。 -
