abstract

initially, the first aim of the present study is to model 3-axle rigid truck by developing a code inmatlab. secondly, each equation should be drived by acquisition of lagrange approach. afterderiving equations successfully, validation is performed by some result which was mentioned inbohao li's master thesis. although the present approach is totally different from the approachthat boahao li used in his analysis but the deviation of the present results from that thesis onaverage is 7 percent which shows an acceptable accuracy in our current numerical approach. inthe present study 19 degree of freedoms is used for determining natural frequency and dominantmotions. by having dominant motion, it is possible to clarify which region is in endangering ofresonance. this paper presents a portion of the results that have been gathered and for watchingnew result in this field, it is recommended to read our future papers. solidworks cad softwareis also used to calculate mass properties of several components that used in our present study.

Study of Vibration Specifications of a Three-axle Truck Using Lagrange Method

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
