Comprehensive simulation test bench for multi-function ship combined power plant

Abstract

A multifunctional comprehensive ship combined power plant simulated experiment platform is divided into three layers from the bottom up; the bottom layer comprises a supporting base plate, which is mounted on a foundation through elastic blocks and provided with longitudinal slide ways; the middle layer comprises supports and holders; and the upper layer comprises two internal combustion engines,a variable-frequency motor, a parallel operation gearbox, a dynamometer, three resilient couplings, a diaphragm coupling, a universal coupling, a long drive shaft, a short connecting shafts, bearings, three torquemeters and sensors, which are mounted on the supports and the holders. The parallel operation gearbox is provided with four connectors, which are respectively connected with the No.1 internal combustion engine, the No.2 internal combustion engine, the variable-frequency motor and the dynamometer through the couplings and the drive shaft system; the experiment platform is provided with two short substitute shafts, the length of one of the short substitute shafts is equal to the universal coupling, the length of the other short substitute shaft is equal to the diaphragm coupling, and the two short substitute shafts can separately or simultaneously substitute the diaphragm coupling and the universal coupling. The experiment platform not only can simulate a variety of ship power systems, but also can conduct a study on the overall performance of a ship power system and a study on the performance of the parts of the ship power system.

Description

technical field [0001] The invention relates to a simulated practical (test) test device, in particular to a comprehensive simulated practical (test) test platform for simulating a combined power device of a ship with multiple practical (test) functions. Background technique [0002] With the shipbuilding industry's improvement of shipbuilding technology, process and quality requirements and the proposal of "low-carbon economy", higher requirements are put forward for the performance of ship power devices, and various new types of power devices continue to emerge and are widely used. . For example, in order to reduce the installation and centering time of the propulsion shaft system and improve the flexibility of manipulation, a universal coupling is installed in the propulsion shaft system; The rotation speed of the internal combustion engine is reduced to an appropriate range; the internal combustion engine must work under the most fuel-efficient working conditions to mee...

Problems solved by technology

However, according to the information consulted, these test benches have single functions and no shaft transmission, so it is difficult to simulate the power plant of a real ship, and it is also impossible to fully simulate the performance of electric propulsion, electric-diesel combined propulsion, propulsion with PTO / PTI device, etc. It is also impossible to carry out tests such as shafting alignment, vibration, and noise in various propulsion forms
