目前在流体力学实验室条件下的造波实验中,对于闸板的升降速度和位置准确度要求是非常高的。但目前在实际实验中,往往都是采用手工拔插的方式,由于闸板重量比较大,需要至少两个人一起在两侧同时用力拔插,这就会造成闸板拔出的时候力度不一致,导致速度和准确度受到影响,从而影响实验效果。因此,基于以上现状,研究一种利用气压传动控制技术来自动调节控制闸板的升降,升降速度可调,升降位置准确,成本低廉,操作简单的新型闸板控制装置具有明显的实用价值。At present, in the wave-making experiments under the conditions of the fluid mechanics laboratory, the requirements for the lifting speed and position accuracy of the ram are very high. But at present, in actual experiments, manual plugging and unplugging is often used. Due to the relatively heavy weight of the ram, at least two people need to pull and plug it hard on both sides at the same time, which will cause inconsistent strength when the ram is pulled out. As a result, the speed and accuracy are affected, thereby affecting the experimental effect. Therefore, based on the above status quo, it is of obvious practical value to study a new type of gate control device that uses pneumatic transmission control technology to automatically adjust and control the lift of the gate, with adjustable lift speed, accurate lift position, low cost and simple operation.
