Comprehensive And Dynamic Study Of Three-slice Parallel Indexing CAM Mechanism

The parallel indexing cam mechanism is widely used in the pharmaceutical,food,printing and other industries,and is a key component for achieving automatic mechanical intermittent motion.Parallel indexing cams are studied through dynamics simulation,dynamic modeling,and thermal analysis.The kinematics analysis of the parallel indexing cam mechanism is carried out.It is concluded that the variation of the angular displacement and the angular velocity of the variable cosine function and the Gatman function are similar,and the variation law of angular acceleration is essentially different.The angular velocity of the output motion corresponding to the cosine function is abrupt at the beginning of the indexing and at the end of the indexing;the angular velocity of the output motion corresponding to the Gateman function is continuous.The transmission function of the indexing cam mechanism is studied.The "bottomup" is used as the basic theory to derive the transmission function.At the same time,the concrete example of the construction function is established,and the transmission function with continuous acceleration and jerk is constructed.This experiment shows that an innovative method of constructing a transmission function is applicable.Based on the analysis of the characteristics of the parallel indexing cam mechanism,the rigid-flexible coupling dynamics model of the parallel indexing cam mechanism was created by Adams,Creo and Ansys.First verify the created model.The main factors affecting the dynamic performance of the mechanism are analyzed,and the effects of dynamics such as center distance and rotational speed on the acceleration of the mechanism are studied.In the steady-state thermal analysis of the mechanism,the model is imported into the software Ansys Workbench,the model is meshed by Steady-State Thermal module.The boundary conditions such as the heat flux of the model are set,and the body temperature of the parallel indexing cam mechanism is obtained by simulation calculation.The influence of the contact surface friction heat on the contact force load distribution and dynamic performance of the parallel indexing cam mechanism is analyzed.Figure 44;Table 3;Reference 56...
