【摘要】 电子器件在使用的时候不可避免的有电磁场的存在,因而会产生电势能。由于电势能的存在,会使系统的一些运动特性发生改变。有些仪器中对电势能处理的好坏将影响到仪器的精度。本文所讨论的就是这样一种情况,传感器中的硅梁,振动过程中受到电场力的作用。文中给出了一种从能量的角度,利用拉格朗日方程对梁的振动进行分析的方法,并将得到的结果与文献[4]中试验结果进行比较,发现此处理方法得到的结果误差较小。更多还原

【Abstract】 While using electronic appliances, it is impossible to avoid the electromagnetic force, and then there will be potential energy of electricity. For this reason, some moving characters of the system change. In some apparatus, the way in which we deal with this energy affects the accuracy of the apparatuses. The literature discusses a condition of this. A beam in a sense organ is affected by electromagnetic force while vibrating. Using Lagrange equation, the literature analyses the vibration of the beam from the point of view of energy. And the result is compared with testing result of literature[4]. A small error is gained.更多还原
