[0039] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0040] The simulation test device 100 and test system for the engine exhaust pipe 300 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0041] As[[ID=3�]] Figures 1 - 4 shown, the simulation test device 100 for the engine exhaust pipe 300 according to the first aspect embodiment of the present utility model includes: a mounting base 1, a first support member 2 and a second support member 3. The first support member 2 is disposed on the mounting base 1, the second support member 3 is disposed on the first support member 2, the second support member 3 is used for mounting the engine supercharger 200, the first support member 2 is movable relative to the mounting base 1 along the first direction X, the second support member 3 is movable relative to the first support member 2 along the second direction Y, and the engine supercharger 200 is movable relative to the second support member 3 along the third direction Z, so that the engine supercharger 200 can be adjusted to the test position, and when the engine supercharger 200 is in the test position, the engine supercharger 200 is adapted to be cooperatively assembled with the engine exhaust pipe 300, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0042] It should be noted that during the engine development stage, the engine needs to be tested. However, the positions of the engine superchargers 200 corresponding to different engines are different. For example, the heights of different engine superchargers 200 relative to the ground or the positions relative to the installation ports of the engine exhaust pipes 300 can be different. Therefore, during the test process, in order to facilitate the fitting and assembly of the engine supercharger 200 and the engine exhaust pipe 300, it is necessary to adjust the outlet position of the engine supercharger 200 to match the position of the installation port of the engine exhaust pipe 300. However, the adjustment means of the previous test devices were not rich enough, and the assembly and debugging process was complex, resulting in low efficiency. It was also not conducive to the subsequent modification of the engine exhaust pipe 300 and difficult to meet the current development requirements of rapid engine replacement.

[0043] Based on this, the present application proposes a simulation test device 100 for an engine exhaust pipe 300. Among them, the simulation test device 100 includes a mounting base 1, a first support member 2, and a second support member 3. It can be understood that the number of mounting bases 1, the number of first support members 2, and the number of second support members 3 are correspondingly set according to the number of engine superchargers 200. For example, as Figure 1 and Figure 2 shown, two engine superchargers 200 are installed on the simulation test device 100. Among them, each engine supercharger 200 corresponds to a mounting base 1, a first support member 2, and a second support member 3.

[0044] Furthermore, when a simulation test is required, as Figure 3 and Figure 4 shown, first, the mounting base 1 is fixedly installed on the ground, or it can also be fixedly installed on the test bench. There is no specific limitation here. Subsequently, simulation adjustment is carried out according to the actual positions of the engine superchargers 200 corresponding to different types of engines. Specifically, by adjusting the position of the first support member 2 on the mounting base 1 in the first direction X (front-back direction), adjusting the position of the second support member 3 on the first support member 2 in the second direction Y (height direction), and adjusting the position of the engine supercharger 200 on the second support member 3 in the third direction Z (left-right direction), the rapid adjustment of the engine supercharger 200 in the up-down, left-right, and front-back positions can finally be achieved, enabling the engine supercharger 200 to quickly reach the test position required for the simulation test. It can be understood that when the engine supercharger 200 moves to the test position, the outlet position of the engine supercharger 200 matches the position of the installation port of the engine exhaust pipe 300, thereby facilitating the installation and cooperation between the engine supercharger 200 and the engine exhaust pipe 300 and improving the assembly efficiency of the engine supercharger 200 and the engine exhaust pipe 300.

[0045] It should be noted that after the position of the engine supercharger 200 is determined, the position of the dynamometer simulation rack 8 can be determined according to the position of the engine supercharger 200, and then subsequent operations such as the modification of the engine exhaust pipe 300 can be realized based on the dynamometer simulation rack 8, which facilitates the subsequent modification of the engine exhaust pipe 300. For example, the simulation test device 100 can meet the modification requirements of the engine exhaust pipes 300 of the existing 145KW, 250KW, 350KW, and 710KW dynamometers in the test laboratory at the same time.

[0046] According to the simulation test device 100 for an engine exhaust pipe 300 of an embodiment of the present invention, the engine supercharger 200 in the simulation test device 100 can move in a first direction X, a second direction Y, and a third direction Z through the cooperation with the first support member 2 and the second support member 3, so that the engine supercharger 200 can be quickly adjusted to the test position, thereby improving the assembly efficiency of the engine supercharger 200 and the engine exhaust pipe 300, facilitating the subsequent modification of the engine exhaust pipe 300, and also being beneficial to improving the development efficiency of the engine.

[0047] In some examples of the present invention, such as Figure 1 and Figure 2 shown, it further includes: a first fastening device 4. The mounting base 1 has a first guide groove 11 extending along the first direction X. The first fastening device 4 includes a first bolt and a first nut. The first bolt sequentially passes through the first support member 2 and the first guide groove 11. The first support member 2 and the mounting base 1 are fixedly connected by the first bolt and the first nut. When the first nut is loosened from the first bolt, the first bolt is movable relative to the first guide groove 11.

[0048] Specifically, the first fastening device 4 includes a first bolt and a first nut. Among them, the first support member 2 is provided with a threaded hole. It can be understood that the position of the threaded hole of the first support member 2 corresponds to the position of the first guide groove 11, and the length of the first bolt is greater than the sum of the height of the first guide groove 11 and the depth of the threaded hole of the first support member 2. In this way, the first bolt can sequentially pass through the first support member 2 and the first guide groove 11. When it is necessary to adjust the relative position of the first support member 2 and the mounting base 1, the first nut and the first bolt are loosened, so that the first bolt can move in the first guide groove 11 along the first direction X to enable the first support member 2 to move to the position to be adjusted. Subsequently, the first nut and the first bolt are tightened, that is, the fixed connection between the first support member 2 and the mounting base 1 is realized through the tightening cooperation of the first bolt and the first nut. When it is necessary to adjust the position of the first support member 2 again, the first nut and the first bolt are loosened again for adjustment. The adjustment method is simple and convenient, and the cost is low.

[0049] In some examples of the present utility model, it further includes: a first driving member fixedly arranged on the mounting base 1, and the first driving member is adapted to drive the first support member 2 to move relative to the mounting base 1 along the first direction X. That is to say, the relative position between the first support member 2 and the mounting base 1 can be adjusted by the first driving member. For example, the first driving member can be a driving motor or a driving cylinder, and no specific limitation is made here. Driving the movement of the first support member 2 by the first driving member is beneficial to improving the automation level of the simulation test device 100, is beneficial to further improving the test efficiency, and the automatic adjustment can utilize programming software to achieve a recording function. When subsequent tests are carried out on the engine types that have been tested, the first support member 2 can be directly moved to the recorded position, which is convenient for subsequent work.

[0050] In some examples of the present utility model, as Figure 1 and Figure 2 shown, it further includes: a second fastening device 5. The first support member 2 has a second guiding groove 21 extending along the second direction Y. The second fastening device 5 includes a second bolt and a second nut. The second bolt sequentially passes through the second support member 3 and the second guiding groove 21, and the first support member 2 and the second support member 3 are fixedly connected by the second bolt and the second nut. When the second nut is loosened from the second bolt, the second bolt is movable relative to the second guiding groove 21.

[0051] Specifically, the second fastening device 5 includes a second bolt and a second nut. Among them, the second support member 3 is provided with a threaded hole. It can be understood that the position of the threaded hole of the second support member 3 corresponds to the position of the second guiding groove 21, and the length of the second bolt is greater than the sum of the height of the second guiding groove 21 and the depth of the threaded hole of the second support member 3. In this way, the second bolt can sequentially pass through the second support member 3 and the second guiding groove 21. When it is necessary to adjust the relative position between the second support member 3 and the first support member 2, loosen the second bolt and the second nut, so that the second bolt can move along the second direction Y in the second guiding groove 21 to enable the second support member 3 to move to the position to be adjusted. Subsequently, tighten the second nut and the second bolt, that is, realize the fixed connection between the second support member 3 and the first support member 2 through the tightening cooperation of the second bolt and the second nut. When it is necessary to adjust the position of the second support member 3 again, simply loosen the second bolt and the second nut for adjustment. The adjustment method is simple and convenient, and the cost is low.

[0052] In some examples of the present utility model, it further includes: a second driving member, which is fixedly arranged on the first support member 2, and the second driving member is adapted to drive the second support member 3 to move relative to the first support member 2 along the second direction Y. That is to say, the relative position between the first support member 2 and the second support member 3 can be adjusted by the second driving member. For example, the second driving member can be a driving motor or a driving cylinder, and no specific limitation is made here. Driving the movement of the second support member 3 by the second driving member is beneficial to improving the automation level of the simulation test device 100, is beneficial to further improving the test efficiency, and the automatic adjustment can utilize programming software to achieve a recording function. When subsequent work is carried out on the tested engine types, the second support member 3 can be directly moved to the recorded position, which is convenient for subsequent work.

[0053] In some examples of the present utility model, such as Figure 1 and Figure 2 as shown, it further includes: a fixing member 6, which is used for fixedly installing the engine supercharger 200, and the fixing member 6 is arranged on the second support member 3 and is movable relative to the second support member 3 along the third direction Z. That is to say, the engine supercharger 200 is fixedly installed on the fixing member 6, the fixing member 6 is arranged on the second support member 3, and the fixing member 6 is movable relative to the second support member 3 along the third direction Z. In this way, the indirect installation of the engine supercharger 200 and the movement of the engine supercharger 200 relative to the second support member 3 in the third direction Z are realized. Further, the fixing member 6 can be configured as a universal fixing device, that is, the fixing member 6 is suitable for the fixed installation of different engine superchargers 200, which is beneficial to improving the versatility of the simulation test device 100.

[0054] In some examples of the present utility model, such as Figure 1 and Figure 2 as shown, it further includes: a third fastening device 7, the second support member 3 has a third guiding groove 31 extending along the third direction Z, the third fastening device 7 includes a third bolt and a third nut, the third bolt sequentially passes through the fixing member 6 and the third guiding groove 31, and the second support member 3 and the fixing member 6 are fixedly connected by the third bolt and the third nut.

[0055] Specifically, the third fastening device 7 includes a third bolt and a third nut. Among them, the fixing member 6 is provided with a threaded hole. It can be understood that the position of the threaded hole of the fixing member 6 corresponds to the position of the third guiding groove 31, and the length of the third bolt is greater than the sum of the height of the third guiding groove 31 and the depth of the threaded hole of the fixing member 6. In this way, the third bolt can pass through the fixing member 6 and the third guiding groove 31 in sequence. When it is necessary to adjust the relative position between the fixing member 6 and the second supporting member 3, loosen the third nut and the third bolt, so that the third bolt can move in the third guiding groove 31 along the third direction Z to move the engine supercharger 200 on the fixing member 6 to the position that needs to be adjusted. Subsequently, tighten the third nut and the third bolt, that is, realize the fixed connection between the fixing member 6 and the second supporting member 3 through the tightening cooperation of the third bolt and the third nut. When it is necessary to adjust the position of the fixing member 6 again, just loosen the third nut and the third bolt again for adjustment.
