Abstract

Semi-active suspension systems have garnered interest in addressing the trade-off between ride comfort and handling of off-road vehicles over rough terrain. This trade-off is challenging due to the on-road handling demand, with high ground clearance and center of mass complicating the matter further. Control strategies such as skyhook and ground-hook control might not be as effective due to the slow response time of the semi-active suspension system being investigated. This necessitates a different approach to leverage the semi-active suspension to improve vehicle ride comfort while maintaining acceptable handling. This study aims to find parameter settings of a semi-active suspension system for optimal ride comfort with a specified handling performance for a range of speeds and terrains, including rough terrains. Results show that optimal settings are relatively insensitive to road roughness but indeed sensitive to speed. Balancing of front and rear axle load transfer hold potential for improving handling without compromising comfort.

乘坐舒适性优化与处理限制在崎岖的地形

半主动悬架系统在解决乘坐舒适性和越野车辆在崎岖地形上的处理之间的权衡方面引起了人们的兴趣。这种权衡是具有挑战性的，因为在道路上的处理需求，高离地间隙和质心使问题进一步复杂化。由于所研究的半主动悬架系统的响应时间较慢，诸如天钩和地钩控制之类的控制策略可能不那么有效。这就需要一种不同的方法来利用半主动悬架来提高车辆的乘坐舒适性，同时保持可接受的操控性。本研究旨在找到半主动悬架系统的参数设置，以获得最佳的乘坐舒适性，并在一定范围的速度和地形（包括粗糙地形）下具有指定的处理性能。结果表明，最优设置对路面粗糙度相对不敏感，但对速度确实敏感。平衡前轴和后轴负载转移持有潜力，以提高处理而不影响舒适性。
