Taking into consideration the mechanical-electric coupling effect under electric load and mechanical load,the load coefficient,and the bar section area as stochastic variables,a formula was proposed to determine safety margins of a bar.

In the piezoelectric truss structure with multi-random parameters,taking the mechanical-electric coupling effect into account under electric load and mechanical load,the formulas of safety margins of bar were proposed by using the intensity of breaking,disruptive electric field intensity,bar section area and loads as stochastic variables.

But the high-order harmonic mechanical-electric coupling vibration caused by high-frequency converting current have significant effect on the stability of grinding systems and grinding quality and its dynamical mechanism is still ambiguous.
