generally the analysis and calculation about a linear suspension system is simplerand more practical. by contrast, that about a non-linear suspention system, for instance,one equipped with air-spring, is rather difficult and complicated for lack of available andeffective solutions at present.taking model d5-260×260 air-spring suspension for example, this paper theoretically and computationally introduces an analytic method, computer-numerical simulation,for analysis and calcullation of the characteristic of non-linear suspension which is to beperformed with the application of numerical differetiation theory, least square curve fittingmethod, and computerbased program and resolution. by the use of such method, muchapplicable information of an air-spring suspension system is easily and accurately obtained,such as rigidity characteristic, vibrational response to e-citation of road roughness, influence on response exerted by amplitude and frequency of e-citation, damp of system, etc.it has high practical value. some experiments have proved this.气弹簧的相关问题可以到网站了解，相信可以帮到您，我们是领域内专业的平台，为您专业服务解答，值得您的信赖和支持。！
