A supporting frame 4 contains an acoustically efficient intermediate mass serving to insulate solid-borne noise.
Description
SYSTEM-ADAPTED ELASTIC MOUNTING
FOR A DIESEL GENERATOR
This invention relates to a mounting for an internal combustion engine connected in driving rela-tion to a machine, such as a diesel engine driving an electric generator, wherein the internal combustion engine and the generator are supported on a supporting frame by first spring elements and the supporting frame is mounted on a foundation by second spring elements.
In the engine driven generator unit disclosed in German Patent document GM 79 32 802, an air receiver by which the internal combustion engine draws in air for combustion, is continued into the supporting frame and the supporting frame has laterally extending air inlet passages. Air guide vanes are inserted in the appropriate part of the supporting frame in order to absorb sound. This design is suitable for a reduction of noise originating in the drawn-in combustion and cooling air, but it does not bring about any advantages with respect to a solid-borne-noise-insulating mounting of the internal combustion engine connected to the generator. One attempt to reduce solid-borne-noise includes filling the supporting frame with concrete to thus create an intermediate mass. Such a concrete intermediate mass, however, brings about only condi-tionally satisfactory results with respect to the insu-lation of solid-borne noise.
It is an object of the invention to furnish a mounting for an internal combustion engine connected to a machine, such as a generator, which effects a marked reduction in the solid-borne noise originating from the internal combustion engine and the generator.
FOR A DIESEL GENERATOR
This invention relates to a mounting for an internal combustion engine connected in driving rela-tion to a machine, such as a diesel engine driving an electric generator, wherein the internal combustion engine and the generator are supported on a supporting frame by first spring elements and the supporting frame is mounted on a foundation by second spring elements.
In the engine driven generator unit disclosed in German Patent document GM 79 32 802, an air receiver by which the internal combustion engine draws in air for combustion, is continued into the supporting frame and the supporting frame has laterally extending air inlet passages. Air guide vanes are inserted in the appropriate part of the supporting frame in order to absorb sound. This design is suitable for a reduction of noise originating in the drawn-in combustion and cooling air, but it does not bring about any advantages with respect to a solid-borne-noise-insulating mounting of the internal combustion engine connected to the generator. One attempt to reduce solid-borne-noise includes filling the supporting frame with concrete to thus create an intermediate mass. Such a concrete intermediate mass, however, brings about only condi-tionally satisfactory results with respect to the insu-lation of solid-borne noise.
It is an object of the invention to furnish a mounting for an internal combustion engine connected to a machine, such as a generator, which effects a marked reduction in the solid-borne noise originating from the internal combustion engine and the generator.
This object is achieved by providing a sup-porting frame containing an acoustically efficient intermediate mass for insulating solid-borne noise, which intermediate mass includes at least two mutually independent components. These two components effect a marked reduction in the solid-borne noise originating from the internal combustion engine and the driven machine. one of the two components uses a material having a high specific mass, while the second component has a lower specific mass such as may be achieved by use of a filler material.
The supporting frame is designed as a trough-shaped steel structure having lateral box girders, the intermediate mass being arranged at least in partial regions of the box girders. These partial regions are chambers that are arranged in distributed fashion in the box girders. One component of the intermediate mass is inserted into the chambers and the second component is inserted into the regions of the box girders lying between the chambers.
The two components of the intermediate mass are preferably sheet-metal stacks and sand. The sheet-metal stacks have a higher specific mass relative to sand and are screwed together with tension rods and lie in the chambers on the box-girder base plate. The tension rods are spaced from the box-girder side walls and from the chamber side walls. A small intermediate space is left between the box-girder side walls and the chamber side walls on the one hand and the sheet-metal stacks on the other, into which intermediate space rubber sheets can be inserted. Fine-grained, dry-calcined sand is filled into the remaining regions of the box girders. The metal sheets themselves are protected against rusting.
The first spring elements are attached, pref-erably screwed, to the sheet-metal stacks. The spring elements are covered at the internal-combustion-engine end and at the generator end by a frame designed in the shape of a trough. This frame contributes to the mutual alignment of the attachments of the spring elements, in particular upon setting-down of the internal combustion engine and the generator and the frame also serves to reduce the emission of airborne sound in the foundation region.
The trough bottom, which closes the entire supporting frame from below, is, like the frame, pref-erably fabricated from sound-deadening sheet metal and thus serves as a shield against amplified emission of airborne noise in the foundation region. This sound-deadening sheet metal is further a steel sheet coated with a bituminous material.
Finally, the internal combustion engine and the generator are enclosed by a housing arranged on the supporting frame.
Further advantages of the invention can be inferred from the description of the drawings, in which:
Figure 1 shows a diesel engine driven genera-tor unit on a supporting frame;
Figure 2 shows a supporting frame having an additional housing enclosing the diesel engine driven generator unit;
Figure 3 is a perspective view of part of the supporting frame;
The supporting frame is designed as a trough-shaped steel structure having lateral box girders, the intermediate mass being arranged at least in partial regions of the box girders. These partial regions are chambers that are arranged in distributed fashion in the box girders. One component of the intermediate mass is inserted into the chambers and the second component is inserted into the regions of the box girders lying between the chambers.

Finally, the internal combustion engine and the generator are enclosed by a housing arranged on the supporting frame.
Further advantages of the invention can be inferred from the description of the drawings, in which:
Figure 1 shows a diesel engine driven genera-tor unit on a supporting frame;
Figure 2 shows a supporting frame having an additional housing enclosing the diesel engine driven generator unit;
Figure 3 is a perspective view of part of the supporting frame;
Figure 4 is a perspective view of the com-plete supporting frame;
Figure 5 is a longitudinal section through the supporting frame of Figure 6;
Figure 6 is a top view of the supporting frame; and Figures 7a to 7c are cross sections through the supporting frame of Figure 6.
In Figure 1, an internal combustion engine 1 drivingly connected to an electric generator 2 by an elastic coupling is mounted on a supporting frame 4 by first spring elements 3 (Figure 3), and the supporting frame 4 is mounted on a foundation, not shown, by second spring elements S.
The internal combustion engine 1 is, for example, a 12 cylinder diesel internal combustion engine of V design having a power of approximately 1300 kW and a weight of about 5000 kilograms or a 16-cylinder diesel internal combustion engine of V design having a power of approximately 1750 kW and a weight of approximately 6500 kilograms. The electric generator 2 is appropriately adapted to the power of the internal combustion engine 1 and has, in the first case, a power of 1800 kW at a weight of 6500 kilograms and, in the second case, a power of approximately 2400 kW at a weight of 7400 kilograms. These diesel engine driven generator units are designed primarily for diesel-electric propulsion of a ship. A plurality of these units can be provided in a ship in order to furnish the requisite propulsive power. Because the diesel engine generator units are the principal noise producers in ships using these units for ship propulsion, this mounting is designed to insulate the solid-borne noise.
Figure 5 is a longitudinal section through the supporting frame of Figure 6;
Figure 6 is a top view of the supporting frame; and Figures 7a to 7c are cross sections through the supporting frame of Figure 6.
In Figure 1, an internal combustion engine 1 drivingly connected to an electric generator 2 by an elastic coupling is mounted on a supporting frame 4 by first spring elements 3 (Figure 3), and the supporting frame 4 is mounted on a foundation, not shown, by second spring elements S.
The internal combustion engine 1 is, for example, a 12 cylinder diesel internal combustion engine of V design having a power of approximately 1300 kW and a weight of about 5000 kilograms or a 16-cylinder diesel internal combustion engine of V design having a power of approximately 1750 kW and a weight of approximately 6500 kilograms. The electric generator 2 is appropriately adapted to the power of the internal combustion engine 1 and has, in the first case, a power of 1800 kW at a weight of 6500 kilograms and, in the second case, a power of approximately 2400 kW at a weight of 7400 kilograms. These diesel engine driven generator units are designed primarily for diesel-electric propulsion of a ship. A plurality of these units can be provided in a ship in order to furnish the requisite propulsive power. Because the diesel engine generator units are the principal noise producers in ships using these units for ship propulsion, this mounting is designed to insulate the solid-borne noise.
Accordingly, the mounting must be carefully designed and, as shown in Figure 2, the internal combustion engine 1 and the generator 2 should be enclosed by a housing 6. In Figure 2, the housing is shown partly open.
Figure 3 shows the supporting frame 4 in a partly assembled condition and Figure 4 shows the sup-porting frame 4 completely assembled. The supporting frame 4 has lateral box girders 8a, 8b, to which inwardly protruding chambers 12a, 12b are attached.
Sheet-metal stacks 7a, 7b lying on the box-girder base plate 10, which are approximately 40mm thick, are inserted into these chambers, the first spring elements 3 being attached to said sheet metal stacks. Between the chambers 12a, 12b, the box girders 8a, 8b are filled with fine-grained dry-calcined sand 18. Between the sheet-metal stacks 7a, 7b on the one hand and, on the other, the box-girder side walls 9a, 9b and the remaining chamber side walls, an intermediate space of approximately 3mm is left, which space can be filled with rubber sheets. As shown in Figure 4, a frame 14 is laid on the spring elements, which, like the trough bottom 13, consists of 10mm thick sound-deadening sheet metal (sandwich sheet) or also only of 10mm thick steel sheet. On the one hand, this frame 14, likewise designed in trough shape, aligns the fastening bolts 15 at the internal-combustion-engine end and at the generator end, and it also contributes, in particular, to further stiffening and reducing the emission of air-borne noise.
Figure 6 is a top view of the supporting frame 4, the frame 14 not yet being assembled in this view. Figures 5 and 7a to 7c show the respectively identified cross sections. In supplement to the fore-going description, it can be inferred from this figure that the chambers 12a, 12b are connected to one another by means of ribs 16a, 16b. These ribs 16a, 16b are connected to the trough bottom 13 and include rein-forcements 17a, 17b on the upper free end. From Figures 7a to 7c, in particular, it can be inferred how the sheet metal stacks 7a, 7b are screwed together with four or, respectively, six tension rods 11 and arranged in the chambers 12a, 12b.
In acoustical terms, this system satisfies the following criteria:
A rigid-body mode lower than 20 hertz is achieved. This criterion, in combination with the spring constants of the first spring elements 5, deter-mines the required mass (mZ) of the intermediate mass plus housing mass (mk). The total mass is thus calcu-lated as m = mZ + mk. For the 12-cylinder engine, mZ is approximately 10,300 kilograms, mk is approximately 2,420 kilograms, and thus m is approximately 12,720 kilograms. For the 16-cylinder engine these valves are mZ = 11,940 kilograms, mk = 2,560 kilograms, and m 14,500 kilograms. The first spring elements 3 are, moreover, designed such that the first characteristic frequency here lies around 500 hertz and the second characteristic frequency around 1000 hertz. The second spring elements 5 are designed such that the first characteristic frequency here lies around 136 hertz.
The number of the first and second spring elements 3, 5 is ten for the 12-cylinder engine and twelve for the 16-cylinder engine. Thus, a fictive matching frequency (dynamic rigidity) of some 8 hertz is achieved between the diesel generator unit and the supporting frame, while in the lower region a characteristic frequency of 3 hertz is achieved between the supporting frame and the foundation.
Figure 3 shows the supporting frame 4 in a partly assembled condition and Figure 4 shows the sup-porting frame 4 completely assembled. The supporting frame 4 has lateral box girders 8a, 8b, to which inwardly protruding chambers 12a, 12b are attached.
Sheet-metal stacks 7a, 7b lying on the box-girder base plate 10, which are approximately 40mm thick, are inserted into these chambers, the first spring elements 3 being attached to said sheet metal stacks. Between the chambers 12a, 12b, the box girders 8a, 8b are filled with fine-grained dry-calcined sand 18. Between the sheet-metal stacks 7a, 7b on the one hand and, on the other, the box-girder side walls 9a, 9b and the remaining chamber side walls, an intermediate space of approximately 3mm is left, which space can be filled with rubber sheets. As shown in Figure 4, a frame 14 is laid on the spring elements, which, like the trough bottom 13, consists of 10mm thick sound-deadening sheet metal (sandwich sheet) or also only of 10mm thick steel sheet. On the one hand, this frame 14, likewise designed in trough shape, aligns the fastening bolts 15 at the internal-combustion-engine end and at the generator end, and it also contributes, in particular, to further stiffening and reducing the emission of air-borne noise.
Figure 6 is a top view of the supporting frame 4, the frame 14 not yet being assembled in this view. Figures 5 and 7a to 7c show the respectively identified cross sections. In supplement to the fore-going description, it can be inferred from this figure that the chambers 12a, 12b are connected to one another by means of ribs 16a, 16b. These ribs 16a, 16b are connected to the trough bottom 13 and include rein-forcements 17a, 17b on the upper free end. From Figures 7a to 7c, in particular, it can be inferred how the sheet metal stacks 7a, 7b are screwed together with four or, respectively, six tension rods 11 and arranged in the chambers 12a, 12b.
In acoustical terms, this system satisfies the following criteria:
A rigid-body mode lower than 20 hertz is achieved. This criterion, in combination with the spring constants of the first spring elements 5, deter-mines the required mass (mZ) of the intermediate mass plus housing mass (mk). The total mass is thus calcu-lated as m = mZ + mk. For the 12-cylinder engine, mZ is approximately 10,300 kilograms, mk is approximately 2,420 kilograms, and thus m is approximately 12,720 kilograms. For the 16-cylinder engine these valves are mZ = 11,940 kilograms, mk = 2,560 kilograms, and m 14,500 kilograms. The first spring elements 3 are, moreover, designed such that the first characteristic frequency here lies around 500 hertz and the second characteristic frequency around 1000 hertz. The second spring elements 5 are designed such that the first characteristic frequency here lies around 136 hertz.
The number of the first and second spring elements 3, 5 is ten for the 12-cylinder engine and twelve for the 16-cylinder engine. Thus, a fictive matching frequency (dynamic rigidity) of some 8 hertz is achieved between the diesel generator unit and the supporting frame, while in the lower region a characteristic frequency of 3 hertz is achieved between the supporting frame and the foundation.
