本文叙述了对我国引进的不平衡响应计算这一先进技术的改进和发展。对复杂的有阻尼振动系统的共振现象给出了新的定义和共振判据,在此基础上把能量——频率特性充实于不平衡响应计算之中,并建立了直接计算共振频率的方法。这些改进和发展扩大了不平衡响应计算的功能,克服了它的缺点。实施这些改进只需对原有程序作较小的补充。
This article describes the improvement and development of the advanced technology for calculating the unbalanced response introduced to our country. A new definition and resonance criterion are given for the resonance phenomenon of a complicated damped vibration system. Based on this, the energy-frequency characteristics are enriched in the calculation of the unbalance response, and a method of directly calculating the resonance frequency is established. These improvements and developments have expanded the function of unbalanced response calculation and overcame its shortcomings. The implementation of these improvements only requires minor additions to the original procedures.
