Tittle Machine design and calculation of parallel four-bar linkage torsion balance
Abstract
Balancing machine as an important part of the rocket takes many forms, such as spring-loaded, pneumatic, and torsion bar. Launch rocket system design in the form of a four-bar linkage of the torsion bar type balancing machine, the design of the forms use the characteristics of parallel four-bar linkage and the characteristics of the stacked plate torsion spring, is a widely used form of balance .
The paper content comes from modern warfare weapons launch platform for fast, flexible, mobile requirements above. The purpose of the research is the development of a high-performance torque balancing machines to meet the large-caliber rockets and tactical performance requirements.
First, the paper analyzes the research and development status of the domestic and foreign-launch rocket system balancing machines, and performance requirements of the rockets, combined with the traditional spring and pneumatic structures, a new balance to adapt to the modern rockets. Secondly, the paper under the above program, the torque balance of the four-bar linkage design and the establishment of a model. Finally, the Matlab software development process to achieve the design parameters and to establish the origin software and computing the results to achieve the automation curves.
