The first picture shows the preparation for physical evaluation of a window-bar installation configuration by Jackson Enterprises Ltd. This evaluation was conducted in an actual vehicle with actual anchorage points in their required locations. Stipulated loads were applied through hydraulics and suitable connections to the anchorage points and the resulting deformations evaluated and documented along with the associated loads that were sustained by the tested items. These results are ultimately used for vehicle certification on related items installed into vehicles used in New Zealand.   This evaluation was conducted successfully for the customer, considering the vehicle certification requirements appicable. The result was an optimum product and eliminating “over-design” which can often be the result of hand-calculations or even F.E.A. (Finite Element Analysis).   Refer to our “LINKS” page for a link to the web-site of Jackson Enterprises Ltd, proudly supported by THOMAS engineers Ltd.   Testing and engineering evaluation in general provides a valuable tool in consideration of the performance of the vehicle structure in addition to the product itself. This is important since, while the product may be adequately designed, if the anchorage points and surrounding structure are not capable of sustaining the imposed loads then failure will effectively occur.   The second picture shows the result of a purposely conducted physical evaluation with inadequate anchorage point consideration. RESULT OF INADEQUATE ANCHORAGE POINT CONSIDERATION This result and all results gained from physical evaluation (or standards testing where conducted) provides a valuable empirical data source which can be used to enhance manual calculation techniques, further refining and streamlining the design process. If you have any special requirements for stressed seat or seat-belt anchorage frame design please contact THOMAS engineers Ltd to discuss. Applications include: Swivel-bases for stressed seats in motor-homes. Window bars for small coaches, taxis or motor-homes. Pillar and frame design for any motor-home seating arrangement configurations. Child restraint anchorages. Physical Testing in General   Thomas Engineers Ltd has had experience in developing a wide range of test equipment, to recognised international standards of performance, for the automotive and pharmaceutical industries, developing equipment such as the following: Salt-spay corrosion testing facility. Stone-chip testing equipment. Capsule dissolution testing equipment. We at Thomas Engineers Ltd have a unique ability to formulate test procedures also for equipment or products not yet covered by any existing standard, contact us to discuss your product development and testing or physical evaluation requirements.   home | services | engineering nz | case studies | contact us | links | site map | disclaimer                                                                         BACK TO TOP Disclaimer : Every effort has been made to ensure that details on this web-site are correct, no item or detail  on this web-site should be used or implemented for any purpose without first consulting THOMAS Engineers Ltd to discuss the application.
