Abstract

A passive loading system for the steering engine of a variable load torque relates to a steering engine loading system. The invention solves the problems that current steering engine loading systems fail to simulate real force condition of steering engines and fail to adjust loading torque at real time, and the problem that the loading system is big in volume. The output shaft of an oil pump motor(3) is connected with an oil pump(2); oil outlets(22-2) of four oil cylinders are respectively communicated with an oil tank(1); the oil inlet of the low-pressure overflow valve(6)of the oil pump is communicated with the oil pump(2), and the oil return port of the low-pressure overflow valve(6)of the oil pump is communicated with the oil tank(1); the oil inlet of a loading proportional overflow valve(7) is communicated with a one-way valve(8), and the oil return port of the loading proportional overflow valve(7) is communicated with the oil tank(1); all the four loading oil cylinders(22)are connected with a tiller(21) and are installed inside a support bracket(25). The passive loading system simulates the real force condition of the steering engine by changing the loading torque at real time.

Description

technical field [0001] The invention relates to a steering gear loading system, in particular to a loading system for a ship steering gear with variable load moment, and belongs to the technical field of ship simulation and testing. Background technique [0002] In the improvement design of the ship's steering gear, it is necessary to carry out the loading test simulating the actual working conditions, which puts forward the development of the steering gear loading system. The ship steering gear loading system requires a loading device that can simulate the water pressure on the rudder surface of the ship during navigation. Its function is to reproduce various loads on the rudder surface in water under laboratory conditions, and change the classic self-destructive full-body test into predictive research under laboratory conditions, so as to shorten the development cycle and save Scientific research funds to improve the reliability of steering gear. The People's Republic of...
