Reducing Automotive Engine Noise with Multidiscipline Simulation

While companies can solve automotive engine noise problems by using engine mounts to stop vibration and the firewall to stop airborne noise, these solutions are not sustainable if one wishes to maintain quality. Therefore, car manufacturers taking advantage of finite element analysis (FEA) software to better understand noise and vibration. FEA can be used to …

Identifying and addressing vibration issues early in the design process

A universal problem when optimizing noise and vibration is that it often conflicts with durability or cost. Multi-body dynamics helps balance these competing requirements early in the design process by addressing key vibration issues facing engineers, such as “will excitations in one part of the systems interaction with another part of the system?” MBD makes …

Accurately predicting load with MBD

At present, most companies use simple hand calculations or results from previous designs to predict loads. Neither of these methods is very accurate. Even small errors in calculating loads create large errors in stress results and very large errors in fatigue life predictions. Accurate loads can be determined by building and testing physical prototypes, but …

Accurately simulating a four-legged walking robot with Adams

Search and rescue operations are extremely dangerous, where even trained men and women face a high risk of injury or death in their effort to save lives. One solution in the face of disasters caused by fires, earthquakes and the like, is designing robots that can reach areas too dangerous for humans. While there are …

New Trailer Suspension Designs Tested in Hours Compared to Days or Weeks

Overview The primary function of heavy duty trailer suspensions is to link the trailer to its wheels. This provides a compliant connection which protects the trailer cargo from the shock and vibration inputs developed at the road surface. In addition, the suspension must meet the customers’ expectations for usable life, and do so while being …

Adams dramatically reduces time to design child safety latch at Kiekert

Car doors are immensely complex systems that serve an immensely important function – safety. The child latch is an additional safety measure, one of many functions a side door latch performs. The child safety lock temporarily disables the operation of the inside door handle. When it is engaged, the rear doors can only be opened …
