Based On Virtual Prototype Technology The Joint Operating Straw Chopping Stubble-breaking Machine Design Of The Key Working Parts

Crushing roller is a straw chopping stubble-breaking machine critical core component of a joint operation, with simple structure, the advantages of good straw chopping effects. However, due to the joint operating straw chopping stubble-breaking machine is the claw hammer-style rotor rotating machinery, and other rotor rotating machinery, as in the actual work process, there is a rotation in the process of dynamic and static imbalances and other issues, resulting in the actual work, produce more large vibration and noise, thus the use of the entire machine performance and adversely affect the working environment. To solve these practical problems, through improved claw hammer crushing roller design methods to optimize grinding rollers arranged claw hammer approach to the layout.Mechanical system dynamics analysis software ADAMS virtual prototype analysis software on the one hand, the user can use the software is very skilled in the virtual prototype dynamics, kinematics and static mechanical analysis. On the other hand, is a virtual prototype of analytical tools and its open program structure and various interfaces, so users can be a special type of special industry analysis of the secondary development of virtual prototyping tool platform. This paper has a joint operating straw chopping stubble-breaking machine critical core component claw hammer crushing roller arranged to study the layout of objects, from the crushing roller arrangement of three different starting claw hammer, according to the theory of rotor dynamics, rotor claw hammer to smash the roll after the discretization , through the lumped parameter method, a grinding roller rotor discrete model, thus confirming the crushing roller rotor critical speed and mode shape, and from the crushing roller balancing point of view of the problem crushing roller rotor vibration generated when the reasons, by claw hammer crushing rollers on the establishment of dynamic balance equation can be solved, and then use PRO / E 3D solid model software built using ADAMS mechanical system dynamics analysis software for each claw hammer crushing roller arrangement of vibration performance of the simulation analysis has been The best claw hammer crushing roller arrangement of the structure of the program.
