In this paper, Using rigid-flexible coupling method the auto synchronous belt drive system dynamics model is established. We can make the rigid-flexible coupling analysis of auto synchronous belt drive system through Recurdyn, designed and auto synchronous belt vibration displacement measurement device was developed, measuring the midpoint of the belt in the process of synchronous belt transmission vibration curve of change over time. Has an important value to improve auto synchronous belt transmission stability and reduce the transmission noise.

To solve the high or low speed air-intake contradictions in the air-intake system of fixed parameters,based on predesigning the air-intake pipe length variable system in electronic controlled gasoline engine, the gas flow in the pipes is computed and simulated according to the simulative calculation method. The Performance of electronically controlled gasoline engine is analysed under the different speed and load.At the end,the dynamic performance influenced by the length parameter vary air-intake pipe,which findings provide a good reference value for the improvement of the engine’s dynamic performance.

AbstractThe noncircular synchronous belt drive mechanism has demonstrated certain achievements and has been used in special fields. Research regarding noncircular synchronous belt drive mechanisms has focused on optimization design and kinematic analysis in China, whereas two pulley noncircular synchronous belt transmissions have been developed overseas. However, owing to the noncircular characteristics of the belt pulley, the real-time variation in the belt length slack during the transmission of the noncircular synchronous belt is significant, resulting in high probabilities of skipping and vibration. In this study, a noncircular tensioning pulley is added to create a stable three-pulley noncircular synchronous belt driving mechanism and a good synchronous belt tensioning, with no skipping; hence, the non-uniform output characteristic of the driven pulley is consistent with the theoretical value. In the circular noncircular noncircular three-pulley noncircular synchronous belt mechanism, the pitch curve of the driving synchronous belt pulley is circular, whereas those of the driven synchronous belt and tensioning pulleys are noncircular. To minimize the slack of the belt length of the synchronous belt and the constraint of the concavity and circumference of the tensioning pulley, an automatic optimization model of the tensioning pulley pitch curve is established. The motion simulation, analysis, and optimization code for a three-belt-pulley noncircular synchronous belt drive mechanism is written, and the variation in belt length slack under different speed ratios is analyzed based on several examples. The testbed for a circular–noncircular–noncircular three-pulley noncircular synchronous belt transmission mechanism is developed. The test shows that the three-pulley noncircular synchronous belt drives well. This study proposes an automatic optimization algorithm for the tensioning pulley pitch curve of a noncircular synchronous belt transmission mechanism; it yields a stable transmission of the noncircular synchronous belt transmission mechanism as well as non-uniform output characteristics.

In order to the integrated design of the geometric parameters and drawing the pulley parts, based on R & D platform of the VBA with the CAD software, hence after analyzing the selection belt type, determine the reference diameter of the belt pulley, choosing length and the amount of the belt, and designing and drawing the pulley parts, in which include the drawing the tooth of v belt pulley, chamfers and grooves, keyway, hatches, and part dimension, etc. Conventional belt drive system is successfully developed. The design results show that the program is running smoothly, the result is correct with the friendly interface, it can provide a convenient tool to rapidly design of project for the belt drive system.
