提出了在高温介质条件下,泵的法兰接头的螺栓计算技术. 应用了马里宁(Malinin)流动理论,得出了一种关系,可用以确定预定时间内零件中的应力下降值或在特写时间内降至一定值的初始应力;这种关系也可用以确定延迟力(初始应力)降至预定值的时间. 并提供了一些数值算例.

Combined with the piezoelectric stack actuator， statically indeterminate truss becomes adaptive structure. The piezo-electric FEM equation of mech-electric coupling is deduced by using Hamilton's principl，on the basis of which the sensitivities of stresses to voltage are acquired. Regarding the input voltage as control variables， the programming model of static strength control is constructed. The correctness and efficiency of the method are illustrated by several examples.
