摘要
Abstract
Vehicle NVH control has gained increasing attention of domestic auto makers in an effort to promote vehicle’s quality. To solve the problem, the integrated product testing and simulation modeling are necessary. One example of system NVH problem that can be benefited by this approach is the powertrain torsional vibration. The key technology in this approach is the development of an effective simulation model. First of all, dynamic parameters such as the torsional stiffness, moment of inertia and torsional damping of individual parts are measured or calculated. Then, these parameters are used to simulate the powertrain torsional vibration for its natural frequencies, mode shapes and frequency responses. With this method, the vehicle’s performance can be optimized easily.关键词
