查询词典 mechanical engineering

The main contents of this paper is used in college to learn the theory of the mechanics, control theory, mechanical design and computer programming technology, and mechanical theory to simulation, including through the establishment of two parts, kinematics and dynamics of the theoretical models (including Straight leg with the knee model and the model), the use of simulation software to achieve the whole process of Walkabout sports simulation, and to study the mass center position, slope angle and other parameters of walking gait characteristics of the device, and to find the law of passive walking, in order to further less energy-consuming research to lay the foundation of the robot.

本文的主要内容就是运用在大学期间所学到的理论力学、控制理论、机械设计以及计算机编程技术，进行理论推导和力学仿真，通过建立包括运动学和动力学两部分的理论模型的（包括直腿模型和带膝关节模型），利用仿真软件实现行走器整个过程的运动仿真，并研究质心位置、斜面倾角等参数对行走器步态特征的影响，从而找出被动行走的规律，为进一步研究耗能少的机器人奠定基础。这一段翻译成英文拜托别用在线翻译那种很多都是错的
