Piston Design Feasibility Study Using ANSYS - An Overview

Deflection Analysis in ANSYS

ANSYS is advanced software that is used in simulating interactions and performance across all disciplines of fluid dynamics, structural, physics, vibration, electromagnetic, and heat transfer, aiding critical decision making and improved operational efficiency.

It facilitates simulating working conditions of a product part, system, or structure, enabling accurate and reliable testing in virtual environment prior to the process of building prototypes of the product. Moreover, it has the capability to develop 3D simulations virtually to identify and improve the weak points, foreseeing the potential problems, and computing the life cycle of the product.

A Piston feasibility study using ANSYS has reported efficient performance and load distribution with improved operational efficiency and minimal development cost and time.

What are the Potential Challenges?

Automobile, aerospace, and other engineering industries face tough challenges in design and development process, which tend to increase reworks and delays while escalating the development costs.

Typically, the design and manufacturing challenges pertaining to engine piston include:
  • Achieving the optimum level of engine performance in addition to cost reduction
  • Need for drastic change in piston design
  • Design changes demand reduction in volume of the existing design
  • Incorporating the changes in the design phase right to actual implementation
  • Determining whether defection and stress produced in the new design are within the set permissible limits
Analysis and Engineering Solutions

Based on the challenges, comprehensive analysis fir effective Piston feasibility study using ANSYS needs to be performed. Typically, increase in deflection and stress can be observed, though the parameters will be within the provided range. It is important to analyse the structure in order to testify feasibility of the proposed design.

Static analysis is to be performed using ANSYS v 14.0 software to conduct a comparison between the existing design of the piston and one that is proposed by calculating the stress and deflection. Analysis with the aid of ANSYS guarantees feasibility of the piston design that is proposed based on stress and deflection.

ANSYS v 14.0 enables developing simulation in virtual environment, providing an opportunity to perform and evaluate the test results. It can also be used to identify any error, loopholes or flaws in the proposed design, providing the opportunity to make necessary changes in the design phase itself. This helps in minimizing the reworks and delays in the project, and also reduces development cost and time.

A comprehensive piston feasibility study using ANSYS enables the engineering and manufacturing industries to make significant design changes and innovation in their product category.
