摘要
本文对具有初速的有限长弹性杆与初始静止的有限长弹性地基梁的横向冲击问题进行了研究,用伽辽金原理求出了冲击力的近似公式并对结果进行了讨论,得出了有关结论.
The normal impacti of an elastic initially static beam of finite length on anelastic foundation by a finite elastic rod with initial velocity is inyestigated inthis paper.The approximate formulas for the impact force are obtained by the Galerkin principle.Some discussions are made and conclusions arc drawn.
