【摘要】 由于受到拟动力实验加载系统和量测系统精度限制，对大刚度结构采用位移控制的拟动力实验方法已失效，本文提出了适用于大刚度结构的力控制拟动力试验方法，阐述了方法的原理与步骤，并用实验实例验证了该方法是可行的和可靠的。更多还原

【Abstract】 By limiting the measured displacement errors of pseudodynamic test systems such as hydraulic actuator and displacement transducers,it is impossible to realize pseudodynamic test in stiff structures. A new pseudodynamic test method,the forcecontrol pseudodynamic test method used in stiff multi-degree-of-freedom structures, has been proposed in this paper.A verification test is done, and the test show that the new pseudodynamic test method can give accurate response and explicit results for stiff multi-degree-of-freedom structures.更多还原
