3D design and the kinematic simulation of the fixture of the drum brake
Abstract
From the birth of the car, the vehicle brake system plays a vital role in the safety of the vehicle. In recent years, with the progress of the vehicle technology and the improvement of the speed of the car, the importance of this kind of performance is becoming more and more obvious.. The research on improving the braking performance of the automobile has become the hot spot of the research.. Drum brakes it cheap, but also conforms to the traditional design, and easy to combine with emergency braking system. In the research, automotive drum brake assembly assembly test platform of 3D design, and carried on the kinematics simulation, and the design of 3D model of 2D engineering drawings and drawing. Through the kinematics simulation of assembly and testing station, before physical prototype manufacturing conveniently predict assembly assembly test bench work process, modify the key dimensions of the key parts of the, reduce movement of key components of uncertainty, so that the automobile brake assembly assembly testing station locating and clamping reliable, fully meet the automotive brake assembly assembly process requirements.
Through this graduation design, systematically consolidate the students should have the basic theory, familiar with the relevant professional knowledge, understand the development trend of the automobile design theory, cultivate the practical ability of engineering design, master the necessary drawing, calculation, studying and referring to Literature and other basic skills and basic process knowledge and strong computer software application ability.
Key words: automotive drum brake assembly; test platform; 3D model; kinematics simulation
