The dynamic analysis of mechanism, the true motion of calcuating mechanism under the effect of the known force system, is generally more troublesome. The key of the dynamic analysis is how to estaklish a systematic kinematic differential equation? the acceleration of calculating mechanism under the effect of the known force system.

The dynamic analysis of mechanism, the true motion of calcuating mechanism under the effect of the known force system, is generally more troublesome. The key of the dynamic analysis is how to estaklish a systematic kinematic differential equation? the acceleration of calculating mechanism under the effect of the known force system. This paper not only introduces the quasi-velocity and the quasi-acceleration of mechanism as,well as their calculating methods, but also applies them to Qktain the equivalent mass of a mechanism J and the calculating formula ahout partial derivative J of and equivalent moment M. They avoid approximate calculation J with fiuite difference and can calculate the accurate value of the acceleration of mechanism under the effect of the known force system. Thus, the kinematic differential equation of the dynamic analysis of mechanism can be got.

机构的动力分析,即计算机构在已知力系作用下的真实运动,通常都较为繁难,其关键是如何建立系统的运动微分方程,即计算机构在已知力系作用下的加速度。本文介绍机构的类速度和类加速度及其计算方法,并运用其推导出了机构等效转动惯量J及其关于φ的偏导数J_φ和等效力矩M的计算公式,避免了用差分法近似计算J_φ,可计算出机构在已知力系作用下加速度的精确值,从而得到机构动力分析的运动微分方程。

The mechanism design was applied to the construction of cylindrical latticed shells and a new method named deployable integral lifting construction technology was proposed. The principle of the method was presented and the kinematic and the dynamic analysis of mechanism was also studied in detail. It is certified that the dynamic performance is unimportant and the shell can bear the load during the erection. This new method has been successfully applied to the cylindrical latticed...

The mechanism design was applied to the construction of cylindrical latticed shells and a new method named deployable integral lifting construction technology was proposed. The principle of the method was presented and the kinematic and the dynamic analysis of mechanism was also studied in detail. It is certified that the dynamic performance is unimportant and the shell can bear the load during the erection. This new method has been successfully applied to the cylindrical latticed shell with the longest span in Asia and the effectiveness of this method is verified.

The kinematic characteristics of 3PSS parallel mechanism was thoroughly analyzed. It was proved in theory that the motion of the movable platform is translation, and this kinematic characteristics of the mechanism was validated by the virtue prototype technology using the software of the dynamic analysis of mechanism systems ADAMS. The workspace of the movable platform of the mechanism was analyzed and the mathematic express of the workspace was given on the base of the theoretical analysis. The 3D configuration of the workspace was drawn up. This will establish the foundation for the locus plan of the mechanism.
