天平试验 meaning in English

balance test

Aero - elastic model tests have a long test period and cost much , high frequency force balance technique can only consider the foundational vibration type of the structure and it must be assumed as linear . because this technique can not get the average wind loads on each floor of the building , it can not give the equivalent design loads of structures
在现行的风洞试验技术中，气动弹性模型试验模型制作复杂、试验周期长、费用高，而高频底座天平试验则只能考虑结构的基阶振型并假定其为线性，且由于只能测得基底倾覆弯矩，无法测量各层的平均风荷载，故而无法确定结构各层的等效设计荷载。
On basis of this property a new type of coherence function was proposed and a simplified method of analyzing structure ' s wind - induced response and equivalent load was proposed . wind tunnel experiments with the caarc standard tall building model was executed to verify the proposed method with the dynamic balance technique . the comparisons show the good agreement on the basis of linear mode shape assumption that is used in balance technique
按照简化方法计算的基底倾覆弯矩功率谱、基底弯矩响应、顶部加速度和位移响应等参数均能与高频底座天平试验的结果较好的符合，等效设计荷载的计算结果也与按照《建筑结构荷载规范》的计算结果具有一定的可比性。
