| With the rapid development of automobile industry, the security, comfort and operational of automobile is getting more and more attention. Wheel is the important of automobile. Whether its performance is good that has a critical influence for the safety and operational of the vehicle.During the detection performance of the wheel,13°wheel impact testing is one of the most basic and the most important testing. So researching and producting13°wheel impact testing which has advanced technology, security and good performance machine has an important significance.By analyzing the principle of testing machine, according to related regulations of state and functional requirements, this paper discusses in detail the design which Including the host, electrical systems, pneumatic systems, the end of the speed detection system and guards equipment. Comparison with similar testing machine, there are creative design in the structural design aspects, such as line round body makes hammer fall more stable, less prone to tilt, the end of the speed detection device are an important basis for recognizing whether the impact test results is effective. In the development process, it combined the impact dynamics and finite element simulation, simulating testing machine when it is in the working environmental conditions. To the key components of the test machine did the Finite Element Analysis. Including Static analysis of mobile beam and wheel bracket and impacting dynamic analysis of the wheel bracket which providing the parameters basis for the structural design and helping optimization of structures. As the impact testing has a greater risk, so the security concept into the entire design process, especially the safety design of lock pin device.After completion of the testing machine. impact testing carried out on the wheel. Analysis were done on the appeared at the end of the speed error. In contrast to similar testing machine, it has excellent performance, high security and a good reference. |
