Design and analysis of piston comparing different materials

  • What are the design considerations for a piston?

     It should provide sufficient bearing area to prevent undue wear.  It should have high speed reciprocation without noise.  It should be of sufficient rigid construction to withstand thermal and mechanical distortions.  It should have sufficient support for the piston pin..

  • What are the different types of piston design?

    There are three types of pistons, each named for its shape: flat top, dome, and dish..

  • What is the best material to make pistons?

    Aluminium alloys are the preferred material for pistons both in gasoline and diesel engines due to their specific characteristics: low density, high thermal conductivity, simple net-shape fabrication techniques (casting and forging), easy machinability, high reliability and very good recycling characteristics..

  • Piston Alloy Comparison
    For most “street” applications and engines with light upgrades, 4032 alloy is a good choice.
    For engines that will see track time or with substantial upgrades in power and torque, 2618 may be a better option.
  • Pistons are produced from cast or forged, high-temperature resistant aluminum silicon alloys.
    There are three basic types of aluminium piston alloys.
    The standard piston alloy is a eutectic Al-12%Si alloy containing in addition approx. 1% each of Cu, Ni and Mg.

What alloys can be used to make a piston?

In Addition to this, some minor alloying elements such as copper and magnesium are used to improve the mechanical properties which in turn results in an increase in the response of alloy towards the heat process

A wide variety of magnesium alloys can be used to manufacture a piston

What is a 3D model of a FEA piston?

A 3D model of the piston is made in CAD Software named SOLIDWORKS

The use of ANSYS Software is made for static structural and thermal stress analyses

Results of the present work foresee the critical area of the FEA pistons and maximum stress

On the basis of results, the optimum or better material is chosen for the piston

Which software is used to model a piston?

In the present paper modelling and analysis of piston is carried out bysolidworks and Ansys software

Designing of the piston is done and calculations are carried out as per the dimensions obtained for the piston

3D-Modelling of the piston is done in solidworks software
