variance lawの例文
- According to the fluctuating property of wind , on the stochastic vibration finite element theory , some calculation formulas of the response , including the along - wind response and the across - wind response , are obtained , the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time . by using the stochastic vibration module of the general finite element program , the paper analyses the performance of the wind resistance more deeply and fully , discussing the influence on the double - tower structure from the diversification of the different component . the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration , so is the effect of several parameters on dynamic displacement , acceleration and wind - induced vibration coefficient
