Simulation Based Design Study of the Smart Cart ME 6105: Modeling & Simulation Dr. Chris Paredis Harjot Hayer Daniel Lai Laura Raibeck
What is the Smart Cart? Motivation: Harjot’s Senior Design Project Brief Description: Modeled after a Hydraulic Scissor Lift Main Objective was to Lift 150 lbs, and to Load onto a Vehicle through a 4-Step Process 12 34 Smart Cart Video
Project Overview Goals of the Design Study: Maximize Usability Minimize Energy Consumption Maximize Performance Design Variables for Study: Size of hydraulic cylinder Input Voltage Hydraulic configuration Measures of Effectiveness: Time to reach height of 1m Energy Consumption (W)
Interesting Results Uncertain Variables were Analyzed in ModelCenter = BAD 2. 1.
Problems Encountered Original Design Study Geometry as a Design Variable Goals Related to Payload Scope of study too large Planar Loops/Singularities! Knowledge of Hydraulics Changing one variable in many places Geometries for all links Friction in joints
What We Learned How to Use Dymola – Steep Learning Curve Organized models are easier to use ModelCenter Modeling preferences is difficult Dealing with uncertainty Don’t leave hydraulics for last
