    Pressurized Hydraulic Reservoir [1<P<5] psig

    I am looking for an economical and reliable method to provide a small mobile hydraulic reservoir with a small amount of positive pressure. Looking for component recommendations for the following ideas. 1. Use air over oil volume as accumulator. Tmin = 32F, Tmax = 150F. System always draws oil...

    12 to 24 vdc onboard battery charging - high current load

    Thanks for the input. Agree with itsmoked about not being most effective method. Pony motor will be a provided option as well as prime mover pump. Unfortunately, many customers want the electric solution mentioned above. Systems of this type have been around in Europe for decades. In fact...

    12 to 24 vdc onboard battery charging - high current load

    I am developing an electromechanical system for a class 8 tractor/trailer rig that requires a large 24 vdc motor to provide hydraulic power to trailer equipment. There is also ancillary equipment such as transducers, valves, and a controller that will consume a small amount of power relative to...

    Recommend Automotive ECU/Motion Control Suppliers?

    Thanks Andy. Do you have experience with any of Parker's associated sensors, particularly the angle sensors? I'm interested in mounting a sensor similar to the RS60 or RS70 to a steer knuckle kingpin, but will need to compensate for radial tolerances during installation and relative axial...

    Recommend Automotive ECU/Motion Control Suppliers?

    Can anyone recommend suppliers that provide automotive rated ECU's capable of closed loop motion control? I am embarking on a large project involving an off-road heavy haul trailer that will include at least 9 axles incorporating closed loop hydraulic steering according to real time ackerman...

    Weld Fatigue Analysis Using BS7608/5400 And FEA

    This question concerns the computation of stresses for use with the set of fatigue curves given in BS7608/5400. Given a complicated steel weldment that does not lend itself to any of the classifications set forth in BS7608/5400, the question is how to compute stress near a weld in question that...
