In chapter 2, the shortcomings of Innas HT are analyzed. A new structure of the HT is proposed to expand the output pressure scope. The pressure fields between the cylinder block and the valve plate and between the valve plate and the end housing have been set up, and the HT is designed and checked. The computational results meet the requirements of the optimum distribution and strength.

第二章，对Innas液压变压器存在的缺陷进行了分析；为拓展液压变压器的调压范围，提出了一种新型结构，并进行结构设计；建立了缸体-配流盘之间，配流盘与后端盖之间的压力场数学模型，并据此对液压变压器进行设计与校核，计算结果满足最佳配流和强度要求。

In chapter 3, the FLUENT software is used to simulate the 2D and 3D fluid fields of three kinds of distribution pairs (cylinder block and piston, valve port and end cap, valve plate and cylinder block).

第三章，利用Fluent流场仿真软件，对液压变压器三个关键配流副(配流盘-后端盖，配流盘-缸体，缸体-柱塞)的流场进行了初步的二维和三维仿真分析，给出了配流盘控制角度为60°下的仿真结果。
