摘要：

Based on thermoelasticity analog method and nonlinear contact finite element method, a full transient model approach is developed, which has three analysis abilities at one time: 1) the electrical-mechanical coupling, 2) the contact effect and 3) the wave propagation. The application of the approach is demonstrated by investigating the contact-impact mechanism of a spring-mounted piezoelectric actuator. The computational precision of the proposed approach is validated by comparing with the experiment data. Numerical results show that the object body behaves three time step-like motion before 6ms and the stick-slip motion can transit many times caused by the friction effect.
