Virtual assembly system based on marine diesel engine

Abstract

The invention discloses a virtual assembly system based on a marine diesel engine. The virtual assembly system is mainly characterized by establishing a diesel engine model through 3dMax and carrying out setting for realizing disassembly and assembly function on each part of the diesel engine model in Unity 3D. The diesel engine model comprises a general assembly and a plurality of subassembly bodies. The virtual assembly system mainly comprises a structure cognition module, an assembly training module and a navigation module. The structure cognition module is used for displaying exploded views of the general assembly and the plurality of subassembly bodies, and when a mouse clicks a part, displaying text messages of the part. The assembly training module comprises a disassembly and assembly animation module and an animation control module. The disassembly and assembly animation module is used for displaying each assembly drawing disassembly and assembly process; and the animation control module is used for controlling states of the disassembly and assembly animation module. The navigation module is used for navigation jump between the structure cognition module and the assembly training module. The virtual assembly system realizes disassembly and assembly training and teaching of the diesel engine without on-site actual operation, and is low in cost and good in teaching effect.

Description

Technical field [0001] The invention belongs to the teaching field of ship main propulsion devices, and relates to a system that allows students to disassemble, install and train and demonstrate the workflow of each component of the diesel engine without leaving the laboratory, and specifically relates to a virtual ship diesel engine-based system. Assembly system. Background technique [0002] The shipping industry is an important national strategic industry related to the people’s livelihood. The ship power plant is the core part of the ship. Its performance greatly affects the maneuverability and safety performance of the entire ship. Marine diesel engines are currently the most commonly used ship. The disassembly, testing and installation of power plant and common diesel engines are the skills that marine engineering and technical personnel must master, and they are also the core courses for colleges and universities and related majors. However, due to the large volume of ma...

AI Technical Summary

Problems solved by technology

The marine diesel engine is huge in shape and complex in structure. In addition to some small socket tools and plum blossom tools, large tools such as lifting equipment are also needed in the disassembly process, which makes various safety hazards hidden in the process of practical teaching. Hidden dangers, out of consideration for the personal safety of students, the instructor has to take various protective measures to ensure the safety of students when leading the practical course, and due to the particularity of the practical course, the training room will only be opened under the leadership of the teacher. Open to the outside world, which greatly restricts the teacher's teaching

Coupled with the limitations of the training room and training time, aging assembly equipment, low safety, too many people and less equipment, lack of teaching assistants, and uneven teaching quality inspections, it is urgent to study a kind of practical teaching for marine diesel engines at this stage. New teaching methods to solve the above problems

[0005] The traditional teaching teacher leads the students to conduct on-site teaching. The teacher disassembles and decomposes the ordinary diesel engine used on the real ship into various parts for explanation, then reinstalls it, repeats the demonstration operation many times, and finally allows the students to disassemble, Installation training, there is a big safety hazard
