| Abstract | Dynamic Simulation and Stress Analysis of Pipe Chain Conveying Systems Student: Guang-Liang Deng Advisor: Kun-Nan Chen Institute of Mechanical Engineering of Tungnan University Abstract Pipe chain conveying systems usually operate in long hours. With static and dynamic simulations, the contacts between the chains and gears and the smoothness of the operation can be examined. This research utilized Ansys Workbench to perform stress analysis and study the contact behaviors of the chains and gears, and also employed MSC Adams to simulate the conveying dynamics of the pipe chain system. The Contact Force Index (CFI), defined by magnifying the effects of unevenly large contact forces, was used to estimate the smoothness of the operation with a smaller value indicating a smoother load to the pipe chain system. For stress analysis, two models were compared, one with a rounding angle of 0 to the driving gear and the other 45, and the results showed that under the same loading condition, the 0 model was a better one. For dynamic simulations, the effects of various rotating speeds of the driving gear and the external tensions on the operation of the pipe chain system were investigated. Four groups of operating conditions, combinations of rotating speeds at 10 rpm and 15 rpm and tensions at 700 kgf and 800 kgf, were studied. The magnitudes of the contact forces, the sum of the areas beneath the contact force curves, the angular velocity of the passive gear and the contact force index were examined. Based on the contact force results, The minimum differential of 1196 N between the maximum and the average contact forces. Based on the results of the contact force curve areas, had the minimum area sum of 28320 N-sec. As for angular velocity, In the right gear part, the smallest difference is about 12 degrees. and for contact force index, group B (700 kgf-15 rpm)attained the minimum CFI .The value is 4106.37 N. Overall, group B was superior to the rest and would likely prolong the operation life of the system. Keywords: Pipe chain conveying system, Dynamic simulation, Stress analysis, Contact force index. |
