独立悬架汽车整车七自由度动力学模型
本文建立了独立悬架汽车整车七自由度动力学模型，推导了振动微分方程，运用数值仿真的手段研究了汽车悬架阻尼系数、刚度等设计参数对汽车振动特性的影响规律。结果表明，在共振区域附近，相对较大的刚度，会导致汽车的舒适性下降，但在共振区以外的高频区，刚度对汽车振动幅值的影响并不大；后桥悬挂阻尼对汽车振动幅值的影响较前桥强烈，适当增大后桥悬挂的阻尼有利于振动幅值的降低(This paper established an independent suspension vehicle dynamic model of seven degree of freedom, the vibration differential equation is derived, using the numerical simulation method of vehicle suspension damping coefficient, influence of design parameters on vehicle vibration characteristics of stiffness. The results show that in the resonance region, a relatively large stiffness, will lead to the comfort of the car down, but in the resonance region outside the high frequency region, the effect of stiffness of the vehicle vibration amplitude is small; the effect of damping on automobile suspension vibration amplitude is strongly increasing the rear axle axle, suspension damping to reduce the vibration amplitude)

GSNNSimulation
本文针对SLAM算法中数据关联过程，提出了一种简单易行的改进方法，将欧氏距离与马氏距离结合用于数据关联。算法不必计算地图所有特征与所有量测之间的马氏距离，而是首先利用相对简单的欧氏距离计算缩小了待关联特征的搜寻范围。利用人工合成数据的仿真结果表明，改进后的数据关联方法可以大幅减少系统计算量，提高关联效率，且不会造成错误关联的增加。(This article SLAM algorithm for data association process, a simple method to Euclidean distance combined with the Mahalanobis distance for data association. Algorithms do not have to calculate all the characteristics of the map with all measurements between the Mahalanobis distance, but the first to use a relatively simple calculation of Euclidean distance to be associated characteristics of narrowing the search. The use of synthetic data simulation results show that the improved methods of data association can significantly reduce the system to calculate the volume and improve the efficiency of association, and will not lead to errors associated with an increase.)
