| 摘要: |
| 本文从理论上论述了:作平面运动的刚体动力学与平面力系静力学之间存在着明显的对应关系,即在动力学中亦存在着解决此类问题的一矩、二矩和三矩方程组三种形式,只不过在动力学中投影方程用的是动量定理,矩方程用的是动量矩定理。应用此原理同样可较方便地解决工程实际问题。 |

| Abstract: |
| This paper deals with the appranent corresponding relations existed between the rigid dynamics and statics in plane motion theoretically,i.e.there exist three forms of one,two and three moment equations to solve this kind of the problem in dynamics.It is only the momentum law that is used in the projection equation of dynamics and the theory of moment of momentum that is used in moment equations. Thus,this theory is easy to use in solving the practical problems in engineering. |
| Key words: rigid dynamics,statics,corresponding relation |
