Concept design of a modular heavy lift beam
No full textThe heavy lift market is characterized by ultra heavy and/or odd sized loads. Heavy transports are unique projects, which are engineered for that one time job. Standard heavy lift and transport equipment is used to the extent possible for each project, but often specialized structures are required. A structure that is often used for this purpose is a heavy lift beam. Heavy lift beams are used for load spreading, as well as applications in horizontal and vertical transport. RollDock is a shipping company that provides worldwide heavy lift services over sea. RollDock is currently in the process of designing a new wide deck heavy lift vessel for loads up to 15000 tons, the Module Carrier (MC). This type of vessel will be put into service in 2015. When loading ultra heavy loads, a support structure is required to prevent damage to the deck due to concentrated loads. Current practice is that this support structure is engineered and manufactured individually for each project. To reduce on engineering and material cost, RollDock has requested to design a standardized steel beam that can be re-used for several projects. For increased productivity of this standardized beam, it must be multi functional to be used for other heavy lift purposes than solely as supports on the MC. These purposes are also found in RollDock’s sister company Roll-Lift, which facilitates heavy lift projects on land. The functions of the beam are determined using past RollDock and Roll-Lift projects, as well as functions that may be useful in future projects. The functions for the modular beam are skid support beam, grillage, different parts of a heavy lift gantry, a vertical spacer and a temporary bridge. The goal of this research is to develop a concept design of a modular, containerized, multi functional beam for heavy lift purposes, with the main purpose to be used for loading the BigRoll MC using platform trailers or skidding.Mechanical, Maritime and Materials EngineeringMarine and Transport TechnologyTransport Engineering and Logistics2014.TEL.785
Evaluation of the quality of postconsumer plastics obtained from disassembly-based recycling strategies
No full textThe focus of the presented research is on the mechanical recycling of postconsumer plastics from Waste Electrical and Electronic Equipment (WEEE). Currently only a limited number of these plastics are mechanically recycled on an industrial scale while the majority is thermally treated for energy recovery. Since there is a significant potential for value recovery and to lower the environmental impact of plastics, the aim of this research is to develop new mechanical recycling processes based on the disassembly of plastic components and the sorting of these plastics based on identification by spectroscopic methods. This study will present this distinct recycling process based on a case study of the recycling of Acrylonitrile Butadiene Styrene terpolymer (ABS) from Liquid Crystal Display (LCD) TVs. The quality of the recyclates is evaluated by mechanical testing and injection molding of thin-walled products. Results showed that with direct reapplication of the obtained ABS without compounding, high mechanical properties could be achieved when compared to postshredder recycled ABS. However, remaining impurities in the polymer matrix limit the applicability of the recycled plastics to components without neither structurally critical nor aesthetical requirements. POLYM. ENG.

Experimental analysis of conformal cooling in SLM produced injection moulds: Effects on process and product quality
No full textIn an injection moulding process, the cooling step takes up to 50% or more of the total cycle time. Therefore, any reduction of the cooling time directly results into an increase of the production rate. Furthermore, products are often rejected because of defects such as warpage or sink marks. The cause of these defects is often an unevenly distributed cooling in the mould due to complex product or mould shapes. A solution for both problems is Conformal Cooling, a technique in which the cooling channels are designed to follow the contour of the mould cavity to obtain an optimal cooling. These often curved cooling channels are difficult or even impossible to produce with conventional techniques such as milling, drilling and EDM. The recent development of the Selective Laser Melting (SLM) 3D printing technology can be used to overcome these limitations. In a previous work [1] the cooling channels of an existing mould to produce sorting trays were assessed and redesigned to achieve a conformal cooled mould. A mould cavity and insert were provided with these cooling channels by means of the SLM technique. In this work the performance of the conformal cooled mould is compared with the original mould based on process characteristics and product measurements. In particular the start-up losses, mould temperature during the cycle, cycle time and product warpage are assessed
Two-component injection moulding of thermoplastics with thermoset rubbers: The effect of the mould temperature distribution
No full textIn a previous study [1] a novel two-component injection moulding process was proposed for combining thermoplastics with thermoset rubber. This process requires moulds in which the cavities for the thermoplastic and the rubber are thermally separated making it possible to use different mould temperatures for both materials. The process starts by first injecting the thermoplastic part. Afterwards the thermoset rubber is injected and vulcanised. The goal of two-component injection moulding is to combine materials within a single product without assembly. Therefore the adhesion strength between the two materials is an important property that detennines the product quality for a two-component injection moulded product. A second important property for every injection moulding process is the cycle time. The cycle time for this specific process is mainly determined by the time required to sufficiently vulcanise the rubber. In this paper the effect of the mould temperature on both the adhesion strength and the vulcanisation time arc investigated experimentally. Products are produced using different mould temperature distributions. Afterwards the adhesion strength is examined using tensile tests. The vulcanisation time is detennined by using hardness measurements to verify the vulcanisation degree of the rubber. Results indicate that higher mould temperatures for the thermoplastic part lead to higher adhesion strength and lower vulcanisation time
