The Establishment And Application Of Online Platform For Theoretical Mechanics Dynamics

In recent years,the online homework system has become more and more widely used in higher education teaching.The survey statistics show that most of the current theoretical mechanics courses in the online homework system are based on multiple choice questions and fill-in-the-blank questions,involving theory.There are few homework systems for mechanics calculation problems.In order to effectively save the teacher's time spent on homework correction and score statistics,and in order to comprehensively assess the students' mastery of the dynamic part of theoretical mechanics,this article uses Python's powerful on the basis of referring to the current mainstream online homework system design model The editing library has established an online platform for theoretical mechanics and dynamics operations.This article mainly does the following three aspects of research work:(1)Compile the theoretical mechanics dynamics graphics library and title library,and store the element information,node information,constraint information,load information,and acceleration information involved in the theoretical mechanics dynamics problem in the specified vectors respectively.Way to reorganize the elements in each vector into a new matrix.Each row vector in the matrix represents a type of question type.According to the classification of the question type in the matrix,a general drawing program is written to draw the schematic diagram of the load,structure and constraints corresponding to the question.By introducing random commands,the randomness within the controllable range of graphics and questions can be achieved to achieve the randomness of the questions.(2)Write a theoretical mechanics dynamic solver,which can solve common dynamic problems.The unit information,node information,constraint information,load information,and acceleration information in the question are input into the program,and the answer information matrix is obtained through the calculation program.According to the needs of the question,the corresponding answer can be retrieved from the answer information matrix.(3)Established an online operation platform to upload the questions to the front-end interface of the network platform.The educational management system designed based on the Django framework is used for the management of teaching activities with homework as the main content,and can also be used to manage the mechanics question bank and assign the school indicators;the teacher management system is designed for teachers to complete according to the teaching tasks.Assignment of assignments;designed student assignment system for students to answer on the front page of the network platform.The establishment of an online platform for theoretical mechanics and dynamic homework is of great significance for improving teaching quality and promoting the development of online education.
