The World's First Gear Grinding Machine for Grinding Internal Gears ...

There is an increasing need for high-precision gear machining to meet customer demand for low-noise and low-vibration planetary gear systems. Mitsubishi Heavy Industries, Ltd. (MHI) has been developing high-precision gear-cutting technologies for use before heat treatment in the production of ring (internal) gears, one of the components of planetary gear systems. However, high-precision high-efficiency gear grinding is also essential after heat treatment to eliminate distortion and improve gear accuracy. In this paper, we report on the development of the Mitsubishi ZI20A grinding machine, the world's first internal gear grinder for use in volume production. Planetary gear systems are widely used in automatic transmissions of vehicles and power transfer systems for hybrid cars because of their compactness and high reduction ratio. There has been an increasing demand for higher precision internal gears as well as for external gears in transmissions to suppress noise and vibration. To meet this demand, gear manufacturers are seeking high-precision high-efficiency techniques for grinding internal gears after heat treatment. Figure 1 shows the manufacturing flow for the volume production of ring (internal) gears. Traditionally, ring gears have often been built into gear systems after heat treatment without being subjected to the finishing process. However, controlling the precision of gears after heat treatment...

Flexible Pipe Stress and Fatigue Analysis - DiVA

Henan Li Marine Technology Submission date: June 2012 Supervisor: Svein Sævik, IMT Norwegian University of Science and Technology Department of Marine Technology THESIS WORK SPRING 2012 for Stud. tech. Henan Li Flexible Pipe Stress and Fatigue Analysis Spennings- og utmatnings-analyse av fleksible stigerø r The flexible riser represents a vital part of many oil and gas production systems. During operation of such risers, several failure incidents may take place e.g. caused by fatigue and corrosion. In limit cases where inspections indicate damage, the decision making with regard to continue operation or replacing the riser may have large economic and environmental consequences. Hence, the decision must be based on accurate models to predict the residual strength of the pipe. In most applications, one or several steel layers are used to carry the hoop stress resulting from internal pressure. This is further combined with two layers of cross-wound armour tendons (typically 40-60 tendons in one layer installed with an angle of 35o with the pipe’s length axis) acting as the steel tensile armour to resist the tension and end cap wall force resulting from pressure. The riser fatigue performance may in many cases be governed by the dynamic stresses in the tensile armour. The existing lifetime models for such structures is primarily based on inherent assumptions with respect to the slip properties of the tensile armour. This thesis work focus on establishing a FEM based model for analysis of the tensile armour, so as to analyse the stress and slip behaviour when exposed to different load conditions. The thesis work is to be based on the project work performed and shall include the following steps: 1) Literature study, including flexible pipe technology, failure modes and design criteria, analytical methods for stress analysis of flexible pipes,...

Coflexip® - Flexible Steel Pipe for Drilling and Service ... - Technip

DESCRIPTION OF A COFLEXIP® FLEXIBLE LINE The Coflexip® Flexible Line Coflexip® products are designed for oilfield services, both on and offshore, where heavy duty is required in combination with Flexible lines are manufactured in long continuous sections (up to several kilometres) and are cut to fit each client's requirements. End fittings with the most common types of end connectors are kept in stock thus minimising delivery times. End connectors not kept in stock will be machined or obtained according to the client's specifications. Delivery time depends mainly on the type of end connectors required and our client’s particular specifications. The pipe structure Coflexip® pipes are composed of successive layers of steel and thermoplastic to produce unique structures that have the strength and durability of steel pipes combined with the flexibility of reinforced rubber hoses. Each layer works independently from the others, as no vulcanisation is used during manufacturing. This results in the structural stability of the pipe. flexibility and Functions of Coflexip® pipe components reliability. These requirements are in applications such as: Choke and kill lines Rotary and vibrator lines Test lines Hydraulic lines Acid and cement lines Nitrogen lines Coflexip® flexible pipes for drilling and service applications are manufactured by the Drilling & Refining Applications Division of the Technip Group 2 1. The thermoplastic inner tube makes the pipe leak-tight. 2. The interlocked zeta and flat steel spiral pressure carcass resist internal pressure and external crushing loads. 3. The intermediate thermoplastic sheath is an anti-friction layer. 4. The double crosswound steel armours resist axial loads, protect the pipe from torsional strain resulting from handling and working conditions. 5. The thermoplastic outer jacket protects the armours from external corrosion. 6. The Stainless Steel Outer Wrap (SSOW), protects the pipe from mechanical impact, abrasion, weathering and accidental mishandling.

BIOFLUID MECHANICS IN FLEXIBLE TUBES James B. Grotberg1 ...

When a flow is driven through a deformable channel or tube, interactions between fluid-mechanical and elastic forces can lead to a variety of biologically significant phenomena, including nonlinear pressure-drop/flow-rate relations, wave propagation, and the generation of instabilities. Understanding the physical origin and nature of these phenomena remains a significant experimental, analytical, and computational challenge, involving unsteady flows at low or high Reynolds numbers, large-amplitude fluid-structure interactions, free-surface flows, and intrinsically 2D or 3D motion. Whereas frequently the internal flow involves a single fluid phase (albeit often of a complex biological fluid such as blood), in many instances the presence of two or more distinct flowing phases is of primary importance (as is the case for air-liquid flows in peripheral lung airways, for example). We divide this review accordingly: Section 2 treats single-phase flows in collapsible tubes, Section 3 covers recent applications of such flows to a wide range of physiological 0066-4189/04/0115-0121$14.00
