Исследование задней подвески мотоцикла

Abstract

Целью настоящей работы является создание оптимальной модели задней подвески мотоцикла с использованием таких методов, как топологическая оптимизация и генеративный дизайн, с помощью которых будет произведена минимизация массы детали при сохранении прочностных характеристик. Данный процесс проводился на основе анализа кинематики и динамики механизма, в котором отражается принцип работы механизма при наезде колеса на какое-либо препятствие. В качестве прототипа для создания области оптимизации была выбрана модель задней подвески мотоцикла Yamaha R1. Для дальнейшего процесса минимизации массы в рамках данной работы были использованы программы: Fusion 360, использующий метод генеративного дизайна и Discovery Live, использующий топологическую оптимизацию, для изучения кинематики и динамики механизма использовался Altair Inspire. Также в ходе работы производилось сравнение нескольких вариантов оптимизированных деталей, созданных с помощью различных программ, использующих разные подходы к данному процессу. Критериями сравнения являлись массовые и прочностные характеристики. Выявлены достоинства и недостатки для каждого метода оптимизации.

The purpose of this work is to create an optimized model of a rear suspension of a motorcycle using two methods such as a topology optimization and generative design. These methods are used for minimization of mass of part and maintaining strength characteristics. The creation is based on kinematic and dynamic analysis which illustrate the principle of operation of the rear suspension when a wheel rides on a ledge or a barrier. The model of the rear suspension of motorcycle Yamaha R1 is taken as a prototype for creating a space design for optimization. There are several programs which is used for minimizing of mass in this research such as Fusion 360, Discovery Live. First one uses the generative design, second one uses topology optimization. Program named Altair Inspire is used for modelling the kinematics and dynamics of the mechanism. Also, in the process of work, there was a comparison of optimized parts created by different programs and different methods of optimization. Mass and strength characteristics were taken as comparison criteria. There are advantages and disadvantages which is found in each method.
