摘要
采用变分原理对试验机－试件系统加载稳定性作了能量分析，得到系统稳定加载准则和失稳准则。分析表明，通过调整加载方式可使试验机－试件系统的参数附合稳定加载或失稳准则。该准则可为伺服控制试验机原理提供理论依据，也可用于围岩－矿柱系统的稳定性分析。
The energy of loading stability is analysed for testing machine-sample system with variationalprinciple,and criteria of stable and nonstable loading are set up.It is showed that the parameters of thetesting machine-sample system may be made to suit to the criteria of stable and nonstable loading byadjusting loading methods. These criteria may be used as the theoretical basis for servo-control testingmachine,and also may be used in the stability analyses of country rock-pillar system.
