A technique based on reduction of order for solving ordinary differential equations is developed to find exact solutions for a generalized KdV-mKdV equation that possesses high order nonlinear terms. The analytical expressions of several types of travelling wave solutions for the equation are obtained in terms of sin, cos, tan, cot, sinh, cosh, tanh, coth and algebraic profiles. It is shown that the wave speed of travelling wave solutions and the coefficient of low order derivative term in the equation are two main factors to determine the change in the physical structures of solutions. 相似文献

<正>简单的CAN ECU时代已经过去;如今,一个典型的ECU会使用到AUTOSAR基础软件的许多功能去实现其复杂的任务。然而越多的功能也意味着越复杂、越宽泛的配置过程。没有工具的支持,开发人员肯定会越来越迷茫。影响ECU配置复杂度的3个因素:更多标准越来越多的ECU软件被定义为AVTOSAR标准基础软件,AUTOSAR中的"配置取代实现"原则要求开发 相似文献

人字齿轮减振降噪的修形设计(英文) 总被引:1,自引:0,他引:1
To reduce vibration and noise and increase transmission efficiency, a three segment method for modifying the pinion profile
was proposed. Cutter surface equations were deduced by changing the shape of the cutter-edge, substituting three segment parabolas
for the line. The influence of longitudinal tooth modifications on tooth surface load distributions was discussed. Transmission
error minimization and uniformity of tooth surface load distribution were chosen as optimization goals and the modified parameters
were obtained by applying the complex method. Finally, an experiment comparing the loaded transmission error, vibration, and
noise both before and after modifications was carried out. The results indicate that the modified design is reliable. 相似文献
