We have made a full theoretical analysis of the wave property and the wave parameters of the flap - type wave generator in the towing tank of our school , and confirmed that should make the factor that the performance of the wave generator give play to normally to influence . in allusion to that the old wave generator can not simulate sea wave , upgrade and transform to this system change the control computer system and install additional d / a change card , redesign the wave control interface and transmission means of control signal , give up the disk machine that can not be used , make the wave - making control voltage signal that has translated direct input the wave controller , make wave controller to make waves through servo system 对我校船模水池原有的摇板式造波系统的性能进行了理论分析,针对水池原有造波机系统模拟海浪的不足,对该系统进行升级与改造,更换了主控计算机并加装d a转换卡,重新设计了造波控制信号的接口与传输方式,舍去了原系统中现已淘汰的磁盘机,使转换后的造波控制电压信号直接输入到造波控制器中,再由造波控制器通过液压伺服系统驱动造波板进行造波。
This paper gave a general method to solve the accelerate damage boundary ( adb ) of the packaging system by finding the adb of two representative packaging systems under type wave . as for the displacement damage boundary ( ddb ) of the packaging system , this paper fist defined the dda of the bilinear packaging system under half - sine wave and other kind packaging systems by analysis . moreover , the course of solve this kind of problem by analysis was given 论文研究了两种典型脉冲激励下的非线性包装系统的加速度损坏边界及其影响因素,总结了求解加速度损坏边界问题的一般思路;针对包装系统的位移损坏边界,文中首次运用解析法确定了半正弦波激励下双线性包装系统的位移损坏边界,归纳了用解析法解决此类问题的一般过程,同时,本文还对此给出了应用更为广泛的一种数值方法。
Physical model test about vertical and several arc type wave screens which were commonly used was carried out , measuring the wave force and overtopping on the wave screens , analyzing the characteristics of wave force and overtopping of different types of wave screens , and researching the mutual relationship between the wave force and overtopping due to different types of wave screens , to service as a reference for wave screen design of sloping breakwater 通过对常用的直立式及几种圆弧式防浪墙进行物理模型试验,测量作用其上的波浪力和越浪量,分析不同防浪墙形式在受力和越浪上各自的特点,并讨论防浪墙型式引起的越浪和受力的相互关系,可供料坡堤防浪墙设计参考。
