| 摘 要： | 将弹性地基视为Vlazov双参数模型，利用二维有限域积分变换的方法推导出了Vlazov双参数弹性地基上四边自由矩形薄板在任意荷载作用下挠度和内力的精确解。在求解过程中，不需要预先人为选取挠度函数，而是直接从弹性薄板的基本方程出发。通过集中荷载计算实例验证了该方法的正确性。该方法计算简便，适用于不同边界的薄板问题求解。

| Abstract: | The theoretical solution of rectangular thin plate on elastic foundation,regarded as Vlazove two-parameter model,with four edges free under arbitrary load is derived by the double finite integral transform method.Since only the basic elasticity equations of the plate are used and there is no need to preselect the deformation function arbitrarily,the solution method is reasonable and theoretical.In order to prove the correction of formulations,the numerical examples of concentrated loading are presented.The ... |
