In this paper, the sine and cosine shaped sensors have been designed by using the integral characteristics of PVDF piezoelectric film. The sine PVDF sensor can be used alone to measure the displacement, speed, acceleration, stain, stress of the roof beam vibration; the cosine PVDF sensor can be used alone to measure the angular displacement and shear of the roof beam vibration; by using them jointly , the structural intensity can be measured for the roof beam without any finite differential error.

本文利用PVDF压电薄膜独特的积分特性，设计制作了正弦形状和余弦形状传感器，它们单独使用，正弦形状的PVDF传感器可以用来测量梁振动的位移、速度、加速度、应变、应力、弯矩；余弦形状的PVDF传感器可以测量振动梁的角位移和剪力；配对使用它们，可以用来测量梁的结构声强，用它们测量结构声强时不会产生有限差分误差。

As a result, it shows thatthe static or dynamic subsystem optimum alone is not equal to the system optimum. Three initial value problems met in the optimal design of flying vehicle are studied andconclusions are derived that: orthogonal test method can be adopted to decide the initial valueof static optimization problem, some mathematical techniques can be used to deal with thecostate variables of Maximum Principle and decide the initial value of the costate variable,the indirect method can be used to get the analytical solution under ideal case to guide thechoice of the initial control curve in the direct method. With some numerical examples oftrajectory optimization, it shows that all these methods are useful not only in accelerating theconvergence but also in converging to the global optimum.
