1、哈尔滨工业大学电算说明书Harbin Institute of Technology课程设计说明书（论文）课程设计说明书（论文）课程名称： 机械设计电算大作业 设计题目： V 带传动电子计算器 院 系： 机电工程学院 班 级： 1508502 设 计 者： 于豪 学 号： 1150850206 指导教师： 曲建俊 设计时间： 2017.10,11 哈尔滨工业大学哈尔滨工业大学电算说明书一、 电算流程图哈尔滨工业大学电算说明书二、 用户界面三、 操作说明（一） 求设计功率和带轮转速：在左侧输入框中依次输入电机功率、电机转速、第一级传动比，并选择工作载荷情况、原动机类型、工作时间，最后勾选特殊工作

2、需求，就可以按“计算设计功率 Pd、带轮转速 n1”键进行一次计算。（二） 确定 V 带类型：根据所求的设计功率和转速，在中央的表中找到对应的 V 带类型，并勾选对应类型的带轮。这时会出现对应的带轮系列直径。（三） 确定小带轮和大带轮直径：在带轮系列中选择一个小带轮直径填入右侧输入框。若 V 带速度合理，则在下方结果处输出大轮小轮直径；若 V 带速度大于最大 V 带速度，则在提示栏提示“choose dd1 again”。（四） 确定中心距和实际基准长度：利用上一步中得出的中心距范围，在输入框中填入初步中心间距，求出初步基准长度。查书上实际基准长度表，获得实际基准长度和对应的带长修正系数，填入

3、右下的输入框中。（五） 输出剩余结果：按下输出结果按钮，计算器自动输出 V 带设计中需要的所有参数到下方的结果显示表中，完成一次计算。哈尔滨工业大学电算说明书四、 电子计算器代码function varargout = trymechanicaldesign(varargin)gui_Singleton = 1;gui_State = struct(gui_Name, mfilename, .gui_Singleton, gui_Singleton, .gui_OpeningFcn, trymechanicaldesign_OpeningFcn, .gui_OutputFcn, trymech
