隨著人們生活水平的提高，對汽車舒適性和操作穩(wěn)定性提出了更高的要求。雖然車的性能可以量化的許多方面，但質量和緩沖兩個方面的性能直接關系到車輛懸掛系統(tǒng)。一般來說，車輛展示良好的平順性的特點是在大型車輛行駛中擁有較低彈簧固有頻率，和較低衰減頻率。車輛展示良好的緩沖一般是懸浮彈簧和阻尼高利率，特別是在中小型車輛中。雖然被動懸架系統(tǒng)可以完善，但現(xiàn)代汽車要求水平道路的處理和較高平順性的共同條件下，這些系統(tǒng)通常不適合用于任何特定類型的地形。 被動懸架的性能在緩沖，平順性行駛，和控制機構方面有著很大的不足
懸掛系統(tǒng)是實現(xiàn)車輛乘坐舒適性和駕駛安全主要組成工具。被動懸架系統(tǒng)的目的是為了在這些目標之間獲得一個良好的緩沖作用，但內在的限制使他們無法
獲得最佳傳動緩沖作用。與被動懸架系統(tǒng)，主動和半主動懸架系統(tǒng)可以實現(xiàn)更好的協(xié)調在各種駕駛中的問題。
With the improvement of people's living, the right vehicle comfort and operational stability of the higher demand. While vehicle performance can be quantified in many ways, ride quality and handling are two aspects of performance directly related to the vehicle suspension system. Generally speaking, vehicles exhibiting good ride quality are characterized by suspensions with low spring rates, low damping rates, resulting in large suspension travel. Vehicles exhibiting good handling generally incorporate suspensions with high spring and damping rates, resulting in small suspension deflections. While the refinement of passive suspension systems for modern automobiles has resulted in acceptable levels of both handling and ride quality under common road conditions, these systems are not typically optimized for any particular type of terrain. Passive suspension performance characteristics still represent a major compromise between ride quality, handling, suspension travel, and controlling body motion.
