Firstly, the existing evaluation methods were reviewed. According to the quality requirement of the actual off-road vehicles, the analysis procedure, simulation method and integrated evaluation criterions were developed. Then, a multi-rigid-body dynamic vehicle model was established with software Adams. Finally, the ride comfort simulation and integrated evaluation were carried out, getting the evaluation indicators including the "Cross-country average velocity" under random road with different level, and the "Limited velocity" allowing to pass the obstacle with different heights. The simulation results show that the ride comfort quality of this vehicle can achieve the design requirements. | | 查看全文查看/发表评论下载PDF阅读器 | |
