摘要
为了提高液力变矩器的性能和效率,在改变叶轮和叶片常规参数的基础上,将仿生学技术融入到叶片设计和试验当中.首先介绍了仿生植物叶片表面和仿生动物皮肤表面设计叶片的思想,然后给出了仿生叶片的制造过程,最后利用研制的试验台对设计的仿生叶片进行了压降性能测试.试验表明,该仿生叶片的减阻特性优于光滑叶片,进而可减小液力变矩器的内部流动损失,提高液力变矩器的整体效率.该试验设计思路和实施过程还可为如何利用仿生学的思想解决工程实践中遇到的问题提供借鉴.
In order to improve the performance and efficiency of the hydrodynamic torque converter,the bionics technology was integrated into the blade designing and testing on the basis of changing the conventional parameters of impeller and blade.Firstly,the designing ideas of bionic plant surface and bionic animal surface were introduced,then the manufacturing process of bionic blade was introduced.Finally,the pressure drop performance of the bionic blade was tested by using the developed test bench.The test showed that the drag reduction characteristic of the bionic blade is better than that of the smooth blade,which could reduce the internal flow loss and improve the overall efficiency of the hydrodynamic torque converter.The designing idea and implementation process of this test could provid a reference for how to use bionics to solve the difficult problems in engineering practice.
