摘　　要：为减小液力制动器设备的体积 ,提出了改变制动器型腔内叶片的安装倾角 ,以提高制动力矩的方法 ,并应用了有限元ANSYS/FLOTRAN软件进行了优化验算 ,优化后的安装倾角能使制动力矩提高 1In order to effectively reduce the outline dimension of the equipment,the assemble angle of blade in impression of the brake was changed to raise the braking moment and a optimize checking calculation by finite element ANSYS/FLOTRAN software was made.The optimized assemble angle is 1.5 times more than the former braking moment.
