摘要
建立开口薄壁杆约束扭转自由振动和强迫振动的微分方程并求得其通解，给出主振型函数的表达式及常见支承条件下杆的频率方程。
Differential equatoins of restrained torsional free/forced vibrations of open thin wall bars are established,and their general solutions are solved The,expression of vibration mode function and frequency equations on usual supports are derived,The forced responses of such bars under different type loads are discussed with generalized functions.
