Description

Technical Field

[0001] This invention belongs to the field of slip ring technology for podded propulsion motor steering, and specifically relates to a slip ring simulation test platform. Background Technology

[0002] The podded thruster can achieve 360° rotation and thrust output during operation. All its internal oil, electrical, and air lines are connected to the external system through slip rings at the nacelle. During operation, the slip rings not only generate heat due to mechanical friction, but the slip rings connecting to the main cable of the podded propulsion motor also generate Joule heating due to resistance. To ensure timely heat dissipation, a heat dissipation path is typically constructed relying on the podded propulsion motor cooling system: the cooling airflow passes through the pod's nacelle, rotor, and stator, then turns back through the slip ring area, and finally flows back to the cooling system to complete the cooling cycle.

[0003] Due to the complex design of the slip ring structure, it not only significantly affects the flow resistance characteristics of the cooling airflow, but also has densely distributed heat-generating components, making it difficult to achieve accurate modeling and analysis using fluid simulation software. Therefore, it is necessary to conduct simulation tests under actual working conditions on the pod steering slip ring.

[0004] Currently, most slip ring tests in the industry are performance verification tests led by manufacturers, and there is a general lack of professional simulation test platforms that can reproduce actual operating conditions, making it difficult to comprehensively evaluate the heat dissipation efficiency and operational reliability of slip rings in real working environments. Summary of the Invention

[0005] The purpose of this invention is to provide a slip ring simulation test platform to solve the problem of slip ring simulation test for pod motor steering.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a slip ring simulation test platform, including a rudder fixing platform for supporting and fixing the rudder assembly, and an air inlet pipe and an air outlet pipe fixedly installed on the rudder fixing platform. A cooling fan located between the air inlet pipe and the air outlet pipe, as well as a motor control box and a current and voltage control box connected to the cooling fan are also fixedly installed on the rudder fixing platform. A sealing component is provided at the outlet of the air outlet pipe, and an intermediate connecting cylinder for docking the slip ring on the rudder assembly is connected to the sealing component.

[0007] The slip ring simulation test platform has wind speed, wind pressure and temperature sensors fixedly installed in its air inlet and air outlet pipes, respectively.

[0008] The slip ring simulation test platform has an upper end connected to the rotating part of the slip ring, a lower end connected to the rotary gear on the rudder assembly, and a middle part in contact with the sealing assembly to form a sealed air passage.

[0009] The slip ring simulation test platform has an air inlet pipe connected to the air inlet of the rudder assembly, and an air outlet pipe in contact with the intermediate connecting cylinder.

[0010] The slip ring simulation test platform has a motor control box that can control the speed of the cooling fan and the steering motor to simulate different steering conditions; the current and voltage control box is connected to the main cable junction box via a cable to simulate the current and voltage passing through the slip ring under different conditions.

[0011] The beneficial effects of this invention are: This invention can simulate the voltage and current passing through the slip ring of the pod propulsion motor under different operating conditions, realistically simulating heat generation. This invention can simulate the steering speed and airflow under different operating conditions, realistically simulating the heat generated by friction during slip ring rotation. This invention uses the steering motor of the steering assembly to drive the slip ring rotation, reducing the need for an additional slip ring drive motor. Attached Figure Description
