Design and Modeling of Ladder Chassis Frame for Toyota Pickup

Abstract

Chassis Means, The French Word That Has Double Meanings. It Means That Either Get-Together Of The Structural Part Of The Vehicle Or The Assembly Of Declared Structural Elements Plus The Mechanical Parts, That Provide To Vehicle Motion In Automotive. Chassis Frame Of Pickup Truck Is Frequently Damaged Due Bumping And Riding Problem During Driving. This Problem Resulted In Reducing Vehicle Performance And Durability. In Existing Pick-Up Deflection And Weight Reduction Of Truck Frame Does Not Fit The Length Of Truck Frame. Therefore, Improvement Is Done In This Design. The Main Objective Of This Work Is To Perform The Design And Modeling Of Ladder Chassis Frame For Toyota Pickup. The Methods Used In This Work Are Mainly Included Analytical Analysis, C++ Computer Programing, And Three-D Autocad Software Ansys Result Validation. The Static Characteristics Included, Recognized Place Of High Stress Area And Deflection For Both Hrcs And Hscs. Enhanced Weight, Strength, And Cost Are Obtained. The Total Load Acting On The Chassis Frame Is 27664.42n And The Load Distribution At Front Hang Is 38% Whereas Rear Hang Is 62%. The Maximum Bending Moment Occurred On The Chassis Frame Is 4386121.5nmm And Maximum Shear Force Is -7570.49n. A Model Is Developed After Chassis Frame Is Modeled By Autocad. Computer Method C++ Is Used For Generated Bending Moment And Shear Force Diagrams As Well As The Result Was Effectively Better. The Result Of Reduction In Weight Is 42.6% For Hrcs And 57.5%.For Hscs. The Deflections Was Also 4mm And 2mm Respectively And The Existing One About 50mm Which Is Greater Than Span Ratio Method 50 Mm >16 And It Is Better And Safe When Deflection Is <16. Therefore By Comparing Weight Reduction And Deflection 4mm Or Hrcs Were Selected In This Paper. Result Is Validated By Ansys And The Deflection Is Measured 3.58mm Which Is Almost Similar With Analytical. Important Recommendation Is Use Experimental Test During Preparing The Prototype. Using This Title, Cost Analysis And Material Optimization Is Recommended For Future Researchers.
