Description

Technical Field

[0001] The invention relates to the technical field of vehicle abnormal noise detection, and in particular to a weathering test system for abnormal noise vibration testing. Background Art

[0002] With the rapid development of the automobile industry and new energy, users have higher and higher requirements for vehicle comfort. Vehicle abnormal noise is one of the important factors affecting user driving experience. When developing automobiles, automobile companies need to carry out abnormal noise and vibration tests on components to determine whether there are abnormal noises in the components.

[0003] Conventional abnormal noise and vibration tests of components are carried out at room temperature, but the actual use environment of automobiles has extreme environments of high and low temperatures. Some components that have passed the abnormal noise and vibration tests at room temperature will produce abnormal noises at high and low temperatures, so extreme environment testing of vehicle components is necessary. The abnormal noise test bench for components usually includes a driving mechanism, a transmission mechanism and a movable platform. The driving mechanism is connected to the movable platform through the transmission mechanism to make the movable platform vibrate and simulate the driving condition of the vehicle. For example, the patent document with application number CN202410080685.9 discloses a vehicle abnormal noise detection platform, which includes a static platform, a dynamic platform and four branch motion chains. The four branch motion chains are driven by hydraulic cylinders or hydraulic motors to make the dynamic platform vibrate. It is generally necessary to provide an exciting force during abnormal noise detection. In the abnormal noise test, there are some multi-degree-of-freedom compound motions. At this time, multiple exciting forces are required to be combined, and the stability of the exciting force is required to be high. High and low temperatures will affect the working stability and service life of the power mechanism. In the above technical solution, the driving mechanism is integrated into the branch motion chain. When conducting weathering tests, the equipment as a whole needs to be placed in a high and low temperature environment. The driving mechanism will inevitably be affected by high and low temperatures, which is not conducive to the implementation of weathering tests. Summary of the invention

[0022] The working principle of this embodiment is as follows: the exciter is arranged in the insulating room and is arranged upward, the upper end of the pull rod passes through the through hole in the middle of the top plate and extends into the temperature-controlled room, the transmission mechanism and the bearing mechanism are arranged on the mounting base, and the transmission mechanism is connected to the part of the pull rod extending into the temperature-controlled room; when it is necessary to apply an exciting force in the x direction, the second transmission force arm is connected to the second transmission docking part through a connecting rod, and an exciting force is applied to the driving force arm through the exciter and the pull rod, and the end of the second transmission force arm is driven to vibrate in the x direction by the principle of lever, thereby applying an exciting force in the x direction to the movable table through the connecting rod; when it is necessary to apply an exciting force in the y direction, the first transmission force arm is connected to the third transmission force arm through a connecting rod. Then, the fourth transmission force arm is connected to the third transmission docking part through a connecting rod, and an exciting force is applied to the driving force arm through the exciter and the pull rod, driving the end of the first transmission force arm to vibrate in the z direction, thereby causing the third transmission force arm to vibrate in the z direction. When the third transmission force arm vibrates in the z direction, the fourth transmission force arm will synchronously vibrate in the y direction, thereby applying an exciting force in the y direction to the movable table through the connecting rod; when it is necessary to apply an exciting force in the z direction, the first transmission force arm is connected to the first transmission docking part through a connecting rod, and an exciting force is applied to the driving force arm through the exciter and the pull rod, driving the end of the first transmission force arm to vibrate in the z direction, thereby applying an exciting force in the z direction to the movable table through the connecting rod. When conducting a weathering test, first adjust the connection mode of the transmission mechanism according to the test requirements. After the adjustment is completed, use the temperature regulating equipment to make the temperature in the temperature-controlled chamber reach the preset value, and then start the exciter to conduct the abnormal sound test.

[0023] In the abnormal sound testing equipment of the present invention, only the driving mechanism contains electrical equipment, and the transmission mechanism and the bearing mechanism are both mechanical parts. The transmission mechanism and the bearing mechanism are exposed to the extreme environment of the temperature-controlled chamber and will not cause obvious interference to the test. The exciter that is susceptible to temperature interference is separately arranged in the temperature-controlled chamber and isolated from the temperature-controlled chamber by an insulation board. The temperature-controlled chamber is not easily affected by the temperature change in the temperature-controlled chamber, and the exciter can maintain a relatively stable working state, thereby ensuring the smooth progress of the weather resistance test. The driving mechanism, transmission mechanism and bearing mechanism of the abnormal sound testing equipment of the present invention are integrated inside the box, and the installation is also relatively convenient. In a further embodiment, the temperature-controlled chamber is connected to a first temperature control device, and the temperature-controlled chamber is connected to a second temperature control device. Since the exciter itself will also generate heat during operation, and the temperature-controlled chamber is small and prone to temperature changes, the second temperature control device can ensure the temperature stability of the temperature-controlled chamber. In one embodiment of the present invention, the second temperature control device can be an exhaust fan, and the insulation chamber is provided with an air path connected to the outside. The exhaust fan can form an airflow to discharge the heat accumulated in the insulation chamber, thereby ensuring that the temperature of the insulation chamber is within the normal working range of the exciter. In another embodiment, the second temperature control device can have an active cooling effect to further prevent heat accumulation in the insulation chamber.

[0024] In some embodiments of the present invention, the movable platform has an x-direction side surface, a z-direction side surface and two y-direction side surfaces, the z-direction side surface is provided with two first transmission docking parts, the x-direction side surface is provided with two second transmission docking parts, and each of the y-direction side surfaces is provided with a third transmission docking part; the two second transmission docking parts, the two second transmission docking parts and the two third transmission docking parts are symmetrically arranged based on the same xz plane; the transmission mechanism includes two transmission groups symmetrically distributed based on the xz plane, each transmission group includes a main transmission member and a secondary transmission member, and each main transmission member is connected to an exciter. The two transmission groups can improve the vibration stability of the movable platform, and in some cases, the two exciters corresponding to the two transmission groups can have different vibration modes, so that the movable platform can simulate different vibration conditions of the vehicle. The base can be provided with a larger insulation room, and the two exciters are placed in the insulation room, or two relatively independent smaller insulation rooms can be provided, and an exciter is placed in each insulation room.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
