【摘要】：碰撞是一復(fù)雜的非線性問(wèn)題,為了研究碰撞作用下結(jié)構(gòu)的響應(yīng),合理的碰撞模型是非常必要的。針對(duì)隔震結(jié)構(gòu)的碰撞現(xiàn)象,結(jié)合改進(jìn)的Kelvin模型和Hertz-damp模型構(gòu)造了一個(gè)新的阻尼函數(shù),提出了改進(jìn)的Hertz-damp碰撞模型,并對(duì)新碰撞模型的可靠性進(jìn)行了數(shù)值驗(yàn)證。通過(guò)現(xiàn)有的碰撞試驗(yàn)和其他碰撞模型對(duì)比,表明改進(jìn)后的Hertzdamp碰撞模型較其他碰撞模型具有較高的精度,能更精確地模擬結(jié)構(gòu)的碰撞響應(yīng)。
[Abstract]:Collision is a complex nonlinear problem. In order to study the response of structure under collision, a reasonable collision model is very necessary.Aiming at the collision phenomenon of isolated structures, a new damping function is constructed by combining the improved Kelvin model and the Hertz-damp model, and the improved Hertz-damp collision model is proposed, and the reliability of the new impact model is verified numerically.By comparing the existing collision tests with other collision models, it is shown that the improved Hertzdamp collision model has higher accuracy than other collision models, and can more accurately simulate the collision response of structures.
