Schmitz Cargobull is using LMS Virtual.Lab simulation software for system-level studies in the development of commercial transportation products.
Schmitz Cargobull makes trailers, container bodies, hauler beds and other commercial truck products for the European market. The company is implementing the LMS solution to help shorten the development cycle and optimise designs for attributes such as lighter weight, smoother ride, improved handling and longer durability.
The solution being implemented by Schmitz Cargobull includes a simulation software suite integrated on the LMS Virtual.Lab platform. LMS Virtual.Lab Motion for multibody simulation lets engineers study the dynamic behavior of the complete suspension system.
LMS Virtual.Lab Durability allows Schmitz Cargobull engineers to predict the fatigue life of components based on dynamic loads. The tight link to multibody simulation means that the Schmitz Cargobull development team can quickly explore the structural strength and fatigue life of numerous items on component and system assembly levels to make appropriate design changes.
To evaluate ride and cornering behavior and determine the associated loads, engineers can use LMS CD Tire to calculate forces from pneumatic tires in contact with 3D road surfaces. The software tracks tire vibrations up to 80Hz, and a road surface interface readily accommodates large sets of digitised test-track data.
One major reason for selecting the software is the tight integration between the various modules, according to Schmitz Cargobull. The LMS Virtual.Lab software suite lets engineers quickly alternate between vehicle dynamics and durability analysis without leaving one application, logging into another and performing time-consuming manual data translations.
Schmitz Cargobull engineers can also study and optimise multiple attributes at the same time, according to the company, especially the many different and often-conflicting engineering requirements for trailer and other vehicle suspension system development.
Since LMS Virtual.Lab works smoothly across a wide range of applications, engineers can also evaluate designs according to various target parameters and quickly arrive at the best possible design. They can develop suspensions and subassembly parts that have adequate strength for reliable performance, for example, without being over-designed and heavier than necessary. Creating more durable designs with less material lowers manufacturing costs and results in lighter-weight, fuel-saving products with longer lifespans.
