In order to improve the efficiency of vehicle engine, a data acquisition system of the cylinder pressure in vehicle engine could be gotten when a fitting formula about cylinder pressure based on different signal of crank speed was established by using function chain neural network. 为了提高车用发动机运行过程经济性,利用函数链神经网络对曲轴转角值所对应的气缸压力数据进行了拟合,得到了基于函数链神经网络的车用发动机气缸压力数据采集系统。
In the paper, inference the position, velocity and acceleration of the driven bar of quadric crank chain when the driving bar are derived, and a computer program based on MATLAB is compiled to simulate the linkage curve, position, velocity and acceleration. 推导铰链四杆机构在主动件处于不同位置时从动件的位置、速度和加速度关系,并编制相应的程序,基于MATLAB对连杆曲线、位置、角速度及角加速度进行计算机运动仿真。
Taking the machining process of a crank in double cavity compressor, this article the agile application of size chain in machining technology. 以双腔压缩机曲轴的加工为例,阐述了尺寸链在工艺加工中的灵活应用。
The relations between the arc and the chord length spread by a curve were used to crank out a table to be looked-up, which simplifies the curvature acquisition into the operation of chain code and looking-up the table. 利用曲线所张成的弓形与弦长之间的关系制成查表,将曲率求取简化为可以递推的链码和查表运算。
