Researchers have investigated direct drive valve for many years to solve problems, such as fluid force imbalance and switching frequency. The structure of the rotary valve has received considerable research interest because of its favorable dynamic properties and simple structure. This paper studied the high frequency double-servo direct drive rotary valve (DDRV), and proposed a novel structure and drive method satisfying high reversing frequency and adequate quantity of flow. Servo motors are integrated into the valve by the innovative structure, which is designed to equilibrate the unbalanced radial fluid force with the symmetric distributed oil ports. Aside from the fast reversing function of the valve, the DDRV presented high performance in linearity of the flow quantity and valve opening as a result of the fan-shaped flow ports. In addition, a computational fluid dynamics (CFD) method based on Fluent was conducted to verify the flux regulation effect of the height change of the adjustable boss.

Design a small flow back-to-back two-stage centrifugal compressor in the aviation turbocharger, the compressor is compact structure, small axial length, light weighted. Stationary parts have a great influence on their overall performance decline. Therefore, the stationary part of the back-to-back two-stage centrifugal compressor should pay full attention to the diffuser, bend, return vane and volute design. Volute also impact downstream return vane, making the flow in circumferential direction is not uniformed, and several blade angle of attack is drastically changed in downstream of the volute with the airflow can not be rotated to required angle. Loading of high-pressure rotor blades change due to non-uniformed of flow in circumferential direction, which makes individual blade load distribution changed, and affected blade passage load decreased to reduce the capability of work, the tip low speed range increases.

DX桩是近年来新兴的一种变截面新桩型。是在钻孔灌注桩的基础上,使用专用挤扩设备在桩底和桩身挤扩成为支盘状,然后浇灌混凝土后形成的桩身、分承力盘和桩根共同承载的桩型。DX桩可较大幅度提高单桩承载力。试验表明单桩承载力比同等条件下的直孔灌注桩提高80 %以上。DX桩可在粘性土、粉土、砂土层、强风化岩、残积土中挤扩承力盘,也可在卵砾石层的上层面挤扩成盘,更适宜在粘性土、粉土或砂土交互分层的地基中使用。DX桩的桩身直径可为400~2 000 mm,桩长可达60多米。是一种值得推广应用的新桩型,已在高层建筑、公路桥
