In this paper, a simulation model of flexible virtual proving ground (VPG) for a car was created in view of the shortcomings of long test cycle and high cost of traditional enhancement test for suspension durability at car development stage, with a variety of durability enhanced roads in the Nong'an Proving Ground as inputs. It solved a string of key technological problems regarding VPG applications. In addition, the time-history dynamic stress response of a car suspension system was analyzed, compared with the real vehicle durability test results obtained under the same conditions. The results of the simulation test and the real test are basically identical in terms of the trend of time and frequency domains. Furthermore, it demonstrates the effectiveness of the simulated suspension system's dynamic stress response for the flexible VPG technology, and realized the effective prediction for the suspension system durability in the development process. © Springer-Verlag 2013.

To reduce the radiated noise of diesel engines, firstly, the contribution of vibro-acoustic radiation is analyzed, and by analyzing the exciting force on the oil pan, the main features of the exciting force in the low frequency are obtained. Then, a constrained optimization model based on the analysis of exciting force is established, and the oil pan structure is optimized to maximize its first natural frequency. Finally, by using the ATV method implemented in *** software, the radiation noises from the vibrating surface of the diesel engine before and after the oil pan optimization are computed respectively so as to explore the correlation between noise reduction and structural vibration. The result shows that the structural acoustic radiation power of the diesel engine reduces 2.3 dB through the structural optimization.

This paper sets the hydraulic engine mount (HEM) of a car as its research object and established the strong fluid-solid interaction finite element model for its property analysis by adopting the INTESIM strong fluid-solid finite element method. A stimulation analysis of the model's static and translation dynamic stiffness characteristics was conducted,compared with the experimental result and the effectiveness of the simulation research findings was verified. The research demonstrates that the translation dynamic characteristics of the HEM can be effectively simulated by the INTESIM strong fluid-solid finite element method;on the basis of which, a preliminary discussion on its torsion dynamic stiffness characteristics was carried out also. © Springer-Verlag 2013.

To achieve the integrated control of body-in-white (BIW) performance at the concept design stage, several parametrical optimization technologies are proposed in this paper in seeking lightweight, stiffness and crashworthiness targets. A professional platform - Concept Analysis and Multi-objective Optimization (CAMO) is developed, which has the capability of the rapid reduction, parametrical simulation and optimization. The optimization algorithms database is developed based on. NET framework to ensure the global convergence and robustness of the optimal results. The theories discussed in the paper are great help of the concept design process improvement, body database development and knowledge utilization. © Springer-Verlag 2013.
