补充资料:广义力
广义力 generalized force 与广义坐标qi对应的力,它的量纲由它与qj的虚位移δqj的乘积为功的物理量决定。若δqj为线位移,则广义力就是作用力;若qi为角位移,则广义力就是力矩。广义力的定义也可以从坐标变换式得来,即(j=1,2…,N),式中Xi为xi方向的作用力;Qj 为与广义坐标qj对应的广义力。N自由度的完整系统(见约束)有N个广义力。对于N自由度的完整保守系统 ,存在势函数V (q1,q2,…qN) 。由于,所以广义力(j=1,2…,N)。用广义力和广义坐标表示的虚位移原理为:。由于δqj的独立性,上式等价于 Qj=0(j=1,2,…N,),即理想完整约束系统平衡的必要和充分条件是全部广义力等于零。 |
