Problems solved by technology

However, the number of motors that can be redundant in the redundant input simulator of this technology is small, so the maximum power that can be reached is small, each motor requires a large power, and the cost is high; The operating tonnage is relatively low, which cannot meet the needs of heavy machinery and equipment such as ocean wave simulation systems, earthquake simulators, and nuclear power plants

Abstract

The invention relates to a parallel-type six-dimensional-output twenty-eight-input redundant fault-tolerant driving simulator which comprises a working platform, three panels, four four-input single-output redundant driving mechanisms and two six-input single-output redundant driving mechanisms. The three panels are mutually perpendicular pairwise, one end of each four-input single-output redundant driving mechanism is fixed on a panel, the other end of each four-input single-output redundant driving mechanism is fixed on the working platform, one end of either six-input single-output redundant driving mechanism is fixed on the panel, and the other end of either six-input single-output redundant driving mechanism is fixed on the working platform. The invention has simple structure and easy control, can obtain greater power by utilizing parallel input, and each interface has the redundance of 4-6 redundant motors so that each motor has lowered power requirements and can differentially output to reach great power and multiple redundant interfaces. Because of adopting the modularized design, the extendibility is strong.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical engineering, in particular to a parallel six-dimensional output 28-input redundant fault-tolerant drive simulator. Background technique [0002] Multi-degree-of-freedom redundant fault-tolerant driving simulators, especially six-degree-of-freedom parallel simulators are mainly used in the manufacture of large-scale simulation equipment, such as wave simulation systems, earthquake simulators, and nuclear power plants. Parallel redundant input drive technology is a technology that uses multiple drive sources to share a total drive force. Through the parallel connection of input drives, a large drive force can be generated through a purely mechanical electrical system without using a huge hydraulic system. , avoiding the risk of high cost and easy pollution. [0003] In the field of parallel mechanisms, redundant input means that the number of kinematic inputs of the mechanism is grea...
