在弹性半空间表面上振动的N条刚性带的弹性动态域(Th Elastodynamic Field of N RigidStrips Vibrating on the surface ofan Elastic Half-Space)I.H.Tan.Shell Research BV.The Ne-therlands. (S2.1) 在弹性半空间表面上彼此平行放置,且被垂直力所和谐地激发的N条刚性带的弹性动态域,现已算出。假设当带运动时,保持刚性带与半空间表面的接触,这不是借助于一个静力叠加在动力上来实现,就是借助于向下质量/弹簧系统(hold-dowm mass/Spring systen)加以实现。并且亦假设在带的下面,弹性介质可以在水平方向任意移动。已经算出总的声辐射功率及其在P波、
Th Elastodynamic Field of N Rigid Strips Vibrating on the surface of an Elastic Half-Space IH Tan.Shell Research BV. The Ne-therlands. (S2.1) Elastic dynamic fields of N rigid belts placed parallel to each other on the surface of the elastic half-space and excited harmoniously by the vertical forces have been calculated. It is assumed that when the belt is moving, the rigid belt is kept in contact with the surface of the half-space, either by means of a static superposition of power or by means of a hold-dowm mass / spring systen. It is also assumed that under the belt, the elastic medium can move freely in the horizontal direction. Having calculated the total acoustic radiation power and its P wave,
