摘要This study uses the piezoelectric technology to collect vibration energy from the ¯xed-¯xed
nonlinear elastic beams attached with the piezo-patch between the two ends. Both single elastic
steel sheet (SESS) and double elastic steel sheet (DESS) systems are investigated and correlated.
To simulate the power generation of the vibration energy harvester (VEH) of both the
SESS and the DESS in di®erent engineering elements, the simple harmonic external force
generated by a shaker at the location of the piezo-patch is used as the source. With this, more
vibration converted electric energy is derived from the transverse deformation and °apping from
the DESS than the SESS beam. The equation of a nonlinear Euler–Bernoulli beam is coupled
with the electric energy equation of the piezo-patch to simulate the SESS VEH system. The
°apping force from the DESS VEH system can be considered the concentrated external load
applied on the SESS beam model. The method of multiple scales (MOMS) is employed to
analyze this nonlinear problem. The ¯xed points plots and the numerical results con¯rm this
theory presented for the two beam systems, which can be used for evaluating similar engineering
systems. Experiments are also performed in this study. The Taguchi method is used to analyze
the optimum locations of the shaker and piezo-patch, as well as the con¯dence level of the
factors. The method of nonlinear analysis presented in this study demonstrates its accuracy
compared with the linear case. The transverse DESS VEH model proposed is proved to be
feasible and more e®ective than the SESS system.
