The vibro-impact systems are familiar with the non-smooth dynamic systems.The dynamics research of the vibro-impact systems not only is significant in theory but also has practical values in engineering.Firstly,using the Poincaré map method,we get an existent criterion of single impact period-n motion in a two-degree-of-freedom vibro-impact system with damper.It is shown that our conclusions are valid through the numerical simulations.Moreover,the satiability of periodic motions is studied and the correspon...

基于Poincaré映射的方法，通过解析的方法导出了一类具有阻尼的两自由度碰撞振动系统的单碰周期n次谐运动存在性判据，经过数值模拟验证了理论分析的正确性，并给出了分析其稳定性的判别公式，通过数值模拟，讨论系统的局部分岔与全局分岔，同时比较了系统参数变化对其周期运动的影响，发现在强阻尼、弱激励、小质量比、较大恢复系数下系统将会出现较多的有规律的周期碰撞。

Results:1 CT demonstrated clear boundary and homogenous density in symptomless, near oval and symmetry. Normal cross section areas of scalene anterior muscle is 1.3793±0.0948cm2, normal CT value is 54.594±2.0106; 2 Cross section form of patient anterior scalene muscle is irregulation, adherence to tissue around, boundary not pure. Statistics display this area and CT value has obvious significant difference in symptomless group and patient group(P.01); 3 After one course, it shows 87.5%/100% of success rate and valid rate respectively in the short-term, as well as 71.8%/93.75% in the long-term.
